00:00Yes, TVS.
00:0330 years ago, a car parts manufacturer in Aichi
00:07invented a technology that would make the world a new normal.
00:12QR Code
00:14QR Codes are essential to our lives, such as tickets and war tickets.
00:22In the 2024 Paris Olympics,
00:24QR Codes were used in traffic control systems,
00:27and they are now spreading all over the world.
00:31The Japanese car parts manufacturer was born.
00:35There were only two members at the beginning of the project.
00:41How did it become a standard project of the time?
00:47Tonight's event is a rally of QR Codes.
00:51Now, the door to space opens.
00:58The backstage of the movement revealed by the QR Codes.
01:06The first is Masahiro Hara, the creator of QR Codes.
01:12Masahiro Hara, the creator of QR Codes
01:16These three people also participated in the development and distribution of QR Codes.
01:26I think many people don't know that Japan is the first country to make QR Codes.
01:32What is the most common use of QR Codes?
01:37The most common use of QR Codes is to access websites,
01:42to use QR Codes to exchange LINE,
01:45and to use them to communicate with various people.
01:52There are no days when you don't see QR Codes.
01:55That's right.
01:56I don't think there's a day when you can't find a QR Code in a room.
02:02I think there is.
02:04How many QR Codes are used per day?
02:08About 5 years ago, the number of QR Codes used per day in China
02:13was about 1 billion per day.
02:17It's definitely more than that.
02:19That's right. We use a variety of QR Codes.
02:22Even at this scale, the number of users is increasing.
02:25It may be an astronomical number.
02:29QR Codes have changed our lives.
02:35What kind of mechanism are they?
02:40QR Codes tell us whether the bar is thick or thin.
02:43The bar is 1.
02:45There is a white space in the space.
02:47That's 0, and it's 1, 0.
02:49It's digital.
02:51QR Codes are arranged in black and white like this.
02:55The bar is 1, and the white space is 0.
02:59The computer handles the 1, 0 numbers.
03:02So QR Codes are made to make it easier to handle.
03:06Bar Codes and QR Codes don't directly convert information into codes.
03:12First, the letters are converted into numbers 0 and 1, which are handled by the computer.
03:17Then, the white space, which is white, is 0.
03:20The black space is 1, and it's converted into a code.
03:24QR Codes are a combination of dots 1 and 0.
03:29But the number of squares is...
03:3264 × 64.
03:34I think it's something like that.
03:36It's 128.
03:37No, no, no.
03:38The smallest QR Code is the one next to it.
03:41It's 21.
03:43So even if you buy a lot of 0 and 1, you can't decide the width like a bar.
03:49That's right.
03:50The bar is the height of the bar.
03:53There's no information here, so it doesn't make much sense.
03:56In the case of QR Codes, if you add more and more squares, you get vertical information.
04:01That's why it's called a two-dimensional code.
04:04In the case of bar codes, which can only provide information in the horizontal direction,
04:08QR Codes are also called two-dimensional codes because they can provide information in the vertical, horizontal, and both directions.
04:16What kind of company is DENSO, which invented such a revolutionary code?
04:23DENSO is a car parts manufacturer.
04:26It's the largest company in the world.
04:32When we were making products, we started using bar codes to manage production.
04:38We started using them to manage production.
04:41Speaking of DENSO, it's a company that has a strong connection with Toyota.
04:45The signage system is famous for Toyota's system.
04:48Did you use bar codes to manage that?
04:50That's right.
04:51The reason why Toyota's signage system was born until then was that
04:55it was just-in-time.
04:57When we needed something, we only made the required amount.
05:00When we needed something, we only made the required amount.
05:05We should have imported it once a week.
05:09But we had to import it many times a day.
05:12At that time, the biggest problem was the bar code processing.
05:16At that time, there was a person who was a professional key puncher on the computer.
05:22He tried his best to hit the keyboard and input information.
05:25There were many mistakes.
05:28He wanted to automate it somehow, so he put a bar code on the sign.
05:32He wanted to automate it somehow, so he put a bar code on the sign.
05:37That's how the bar code came into being.
05:40That's how the bar code came into being.
05:45Yes.
05:46He had the bar code on the sign for 90 degrees.
05:51He just put the bar code in a row.
05:54So, there are a lot of bar codes.
05:56Yes.
05:57So, there are a lot of bar codes.
05:59Yes.
06:00As a reading device,
06:02we call it a paper-sending system at the station's ticket office.
06:06We call it a paper-sending system at the station's ticket office.
06:10A reading device was as big as a 50-centimeter cube.
06:15What kind of information is written on this sign?
06:20First of all, there is information such as the number of parts of the product,
06:25the number of input units,
06:27where the product is made,
06:31and where it is brought to the factory.
06:35All the necessary information is included in this.
06:37And if there is a defect,
06:39you can calculate which line has which problem.
06:42I think this is a very convenient system.
06:45But it's not enough to move on to the QR code from here.
06:50Yes.
06:51The reading device is so big that it's hard to read.
06:54Now, you can hold it in your hand at the convenience store.
06:58You can't handle it unless you're a leader who holds it by hand.
07:03I see.
07:04As for the product delivery site,
07:07I lined up about 10 barcodes and read them one by one.
07:11Then, it takes 10 seconds to read one by one.
07:18And if you read thousands of barcodes a day,
07:21the workers get tired.
07:23If you don't read them in the same order,
07:25the data will change again if they are misaligned.
07:27That's right.
07:28And just as the bubble collapsed,
07:30mass production turned into mass production.
07:33And since things are no longer sold,
07:36especially in the automobile industry,
07:38various cars have been added to meet the needs of users.
07:42Yes, the number of options has increased.
07:44And the number of parts has increased a lot.
07:47So, in order to manage the production in detail,
07:50we had to print several barcodes.
07:52I see.
07:53At that time, when we were at Densou Wave,
07:56we were told to come and see the barcodes
07:59because it was difficult to read them.
08:02When we went to see the barcodes,
08:04the workers were reading them one by one,
08:06and it looked like a lot of work.
08:08So, I thought that the number of barcodes
08:10would be limited in the future information age.
08:12I see.
08:13And one more thing.
08:15Automobile factories use oil.
08:18If the barcodes are dirty with oil,
08:20the bar will tell you the information in terms of width.
08:24So, if there is oil on a thin bar,
08:26it will get thicker, and if you can't read it,
08:28it will be read as different data.
08:30So, what we did was that
08:32if we made a mistake,
08:34we read the same barcode about 10 times
08:37and decided the data by multiple choices.
08:39I see.
08:40Which one is more reliable?
08:42If you think about it like that,
08:44it's very difficult to work with.
08:46I see.
08:47The workers were having a hard time,
08:49so we wanted to solve it several times,
08:51so we developed QR codes.
08:53With the diversification of needs,
08:55we needed to manage production in more detail,
08:59but the quality of the data was poor
09:01because of the oil stains.
09:03The site was in a state of crisis.
09:05Mr. Hara decided to develop a completely new code
09:09to solve the problems of the past
09:11with a sincere voice saying,
09:13I want you to do something about it.
09:16As a company,
09:17instead of having it made from scratch,
09:19if there is an existing one,
09:21what do you mean by saying
09:23it's better to change it a little
09:25and it won't cost much?
09:26Yes, there was.
09:27I see.
09:28But when we were looking at our own know-how,
09:33it was difficult to read this code,
09:35so we thought it would be better
09:37to believe in our own know-how
09:39and do it ourselves.
09:41I think we were a little self-satisfied.
09:47But I don't think the company
09:49will be able to do it that well,
09:51so I told them to do it by themselves
09:53so that they could do it.
09:55I told them to do it by themselves
09:57so that they could do it.
09:58So you had already decided on the resource and the type?
10:00Yes, I decided on it myself.
10:01I told them that if they went any further,
10:03I wouldn't let them do it.
10:04Especially after the bubble collapsed,
10:06we didn't have a budget.
10:07So I told them to do it
10:09if they were determined to do it.
10:12I see.
10:13I told them that it would be a pity
10:15to do it by themselves,
10:17so I told them to do it with Watabe.
10:19So we decided to do it together.
10:21When you were told that there was
10:23such a project,
10:24how did you feel?
10:26At that time,
10:28I was working with Hara,
10:30and it was just the right time
10:32to finish my work,
10:34so I felt like
10:36the next job was about to start.
10:38I thought it was interesting,
10:40but at that time,
10:42I didn't have that much enthusiasm
10:44like Hara did.
10:46But as I was doing it,
10:48I thought that I should
10:50make something good.
10:52I think that passion
10:54led me to do it.
10:56I see.
10:57The world-changing invention,
10:59QR code.
11:01However,
11:03it wasn't a big project
11:05that started with a company,
11:07and the time and budget were minimal.
11:09From there,
11:11the days of endless trial and error began.
11:13At that time,
11:15was there no other 2D code?
11:17I think barcode itself
11:19was born in the United States.
11:21Yes,
11:22when I was developing it,
11:24it was a bit ahead of its time
11:26in the United States.
11:28At that time,
11:30I was going to use
11:32what was being developed
11:34in the United States
11:36as a reading device,
11:38but at that time,
11:40the performance was bad
11:42and the reading was weak,
11:44so I thought it would be better
11:46to make it myself
11:48because it couldn't be used
11:50in the United States.
11:52In this case,
11:54which part is not easy to use?
11:56Well,
11:58the data matrix is
12:00an L shape on the left side
12:02and the bottom side.
12:04It's a hard line.
12:06It's designed to determine
12:08the outline or boundary of the code
12:10and take out only the code.
12:12It's a standard landmark.
12:14However,
12:16because it is printed on such a print,
12:18it can be mistaken for an L shape.
12:20I see.
12:22It was very difficult to extract
12:24only the code from there.
12:26Because the shape is too common.
12:28Yes.
12:30The data matrix,
12:32which had already been operated
12:34in the United States,
12:36was designed to mark
12:38the outline of the L shape
12:40and identify the code,
12:42but by using the L shape
12:44as a landmark,
12:46Mr. Hara had trouble
12:48finding the code
12:50and had a problem
12:52that it took a long time
12:54to read and write.
12:56Therefore,
12:58Mr. Hara decided
13:00to create the world's first code
13:02that solves all the problems
13:04of conventional barcodes
13:06and leading manufacturers.
13:08First, he set three goals
13:10and started development.
13:12What did he do
13:14when he was a kid?
13:16The first thing he did
13:18was to make a cutie code.
13:20The company's image is different,
13:22so he did the opposite.
13:24He imitated a cutie code.
13:26The son of a single man
13:28suddenly came back
13:30again.
13:32I suddenly feel hungry.
13:34What is that?
13:36Why is the air in my family
13:38strangely relaxing?
13:40Isn't it because you've been eating
13:42for a long time?
13:44My body is made of the air
13:46in my family.
13:48I keep looking at the air
13:50in my daily life.
13:52A new common sense
13:54created from awareness.
13:56Nocturia.
13:58Drinking too much,
14:00stress,
14:02and irregular eating habits
14:04cause liver failure.
14:06Please listen to
14:08Harasawa Pharmaceutical's
14:10PAPINARIN,
14:12which can be applied
14:14directly to the ears.
14:16It has a double effect
14:18on both acne and bacteria.
14:20PAPINARIN,
14:22Harasawa Pharmaceutical.
14:24Every time we meet beautiful Japan,
14:26Wednesday at 9 p.m.
14:28He set three goals
14:30in order to solve
14:32the challenges
14:34of conventional barcodes
14:36and flash manufacturers.
14:38What should we do
14:40to make it happen?
14:44As I explained earlier,
14:46barcodes are information
14:48about the width of the bar,
14:50so only horizontal information
14:52can be entered.
14:54But QR codes can be entered
14:56vertically and horizontally,
14:58so a lot of information
15:00can be entered.
15:02Another thing is that
15:04it can be read quickly.
15:06The reason why it can be read
15:08quickly is that
15:10there are three QR symbols
15:12and a mark.
15:14This mark is composed
15:16of black and white ratios
15:18where letters are composed.
15:20This square shape
15:22has a shape,
15:24but this width
15:26can't be seen elsewhere?
15:28Yes.
15:30I see.
15:32Is it like
15:34one-to-one ratio?
15:36Yes, it is.
15:38In the case of Gothic,
15:40it is one-to-four ratio.
15:42The width is thick,
15:44so there is almost
15:46no ratio of letters.
15:48It's amazing that
15:50there is no other
15:52simple shape.
15:54Yes.
15:56I had a hard time
15:58finding it.
16:00How do you find it?
16:02When you choose a complex shape,
16:04it takes a long time
16:06to recognize the shape
16:08on a computer.
16:10The reason why
16:12a computer can process
16:14letters quickly is
16:16the ratio of bars.
16:18I don't know if there is
16:20a pattern that
16:22doesn't have a ratio
16:24in such letters,
16:26but I did a lot of things
16:28and couldn't come up with
16:30a ratio of letters.
16:32I took all the images
16:34and made a software
16:36to measure the width.
16:38As a result,
16:40I found that
16:42black is 1,
16:44white is 3,
16:46black is 1,
16:48black is 1,
16:50black is 1,
16:52black is 1,
16:54black is 1,
16:56black is 1,
16:58black is 1.
17:00Yes.
17:02It takes about 5 seconds
17:04to recognize the shape
17:06on the screen,
17:08and there is a difference
17:10between letters.
17:14With the invention of
17:16figure symbols,
17:18the quickness of reading
17:20has succeeded
17:22in growing significantly.
17:24Here is video
17:26This is how much I can read in one second, about 30 times.
17:36For example, with a barcode that doesn't have much information, can you read this much?
17:46Yes, I can read this much with a barcode.
17:50The speed of reading a QR code is about 5 times the speed of reading a barcode.
17:58So you can read more information at the same speed as before?
18:01Yes, I can read more information.
18:03Are all the data in the QR code 0x01?
18:07Or is it divided like this in this space?
18:12No, I just make a list of numbers and put the data in order.
18:23The real data is this much.
18:27In addition to that, there are a lot of other data that can be used to make assumptions.
18:38To put it simply, it's like reading a number.
18:45You can read a number from 1 to 9.
18:48Depending on the rule, you can read a number from 1 to 9.
18:53I see.
18:54So if you can read 3 numbers in this space, you can only read this number in the QR code, right?
19:00Yes, that's the idea.
19:02That's where you can make assumptions.
19:07So you can reproduce 30% of the code area.
19:12At that time, the data for the assumption is about 70%.
19:19So it's mostly data for making assumptions.
19:22So it's designed to be dirty, right?
19:24That's right.
19:25This is what we were able to do because we were in the automobile parts manufacturer.
19:28If I were in an IT company, I wouldn't have thought about such a dirty thing.
19:33It would have been more rational.
19:36On the contrary, it would have been harder to read.
19:39I see.
19:40People often ask me why an automobile parts manufacturer was able to make such a thing.
19:45I think that's where the necessity of being able to make it is.
19:50The QR code, which is made up of various ingenuities, was completed in two years as promised.
19:57The development is in the next step.
20:00We made a prototype for the demo machine and exhibited it at exhibitions.
20:07It was read very quickly, so people asked,
20:10Are you really reading this?
20:15What kind of demo is that?
20:16Do you read the data you're given in two dimensions?
20:19It's done, right?
20:21Yes.
20:22You can read what's moving at high speed in the demo machine.
20:27If you show that you can read even if it's dirty or read quickly,
20:31people around you will say,
20:33Wow, that's a great code.
20:36But the company said,
20:38I don't know if this code will really work in business.
20:44For about half a year, I went to PR for customers and business associations.
20:51I was told that it was a great code and could be used in many ways.
20:56So the company decided to start a business with it.
21:02So you wanted it to be used in factories, right?
21:06The factory was using barcodes at first,
21:09so I thought it would be the fastest development.
21:13Of course, the idea was to make a QR code,
21:18but you also had to make a part that could be read.
21:23You can't make a QR code even if you can read it, right?
21:27How do you divide the time to make it?
21:30At first, the company didn't know if it would sell in business.
21:35Especially in hardware development, it takes a lot of money.
21:39So, as I said earlier,
21:41we did a market survey and decided to develop it if it could be used in business.
21:46So after half a year, we started developing the reading device.
21:51After about a year and a half, we were able to develop a mass production machine.
21:57He developed a variety of reading devices that could be used in various situations.
22:02He was particular about other than technical aspects.
22:07When people use it,
22:09it is necessary to develop a reading device that people can read quickly and comfortably.
22:20At that time, I was working on a product plan,
22:25but I was also particular about sound.
22:28When I read the word, I felt that people's ears felt very comfortable when the sound was good.
22:37So I went to various members, such as Mahara,
22:40and asked them to make various sounds.
22:43I also asked them to make a sound that would bring out the characteristics of this QR code.
22:49It's better to have a sense of reading.
22:52It feels good, doesn't it?
22:54How comfortable is the sound?
22:58Well, there are quite a few.
23:02At that time, Mahara and I discussed it,
23:06but I thought it would be better to have an ear-catching sound,
23:09like a crackling sound.
23:11But recently, I've been thinking about a higher and shorter sound.
23:15I felt that it was a little different at that time.
23:18When I heard that sound, I thought it was a pretty old model.
23:22When did the name QR code come up?
23:26Did it have a project name from the beginning?
23:30At that time, the company was based in Nippon Denso,
23:35so they called it ND code.
23:38When it was completed and announced in the newspaper,
23:44I thought there was no name.
23:46There was only a development code.
23:48So I decided to give it a name.
23:51At first, I named it QUICK TAG.
23:55TAG is an acronym.
23:58It's a tag that reacts quickly with the acronym.
24:01I named it QT code.
24:03After all, speed is the best selling point.
24:05At that time, there was a revival of the QT version of the manga.
24:13I thought the image of the company was a little different, so I was opposed to it.
24:18Did you think of QT Honey?
24:20Yes.
24:21I see.
24:23The top salesperson of the company said,
24:25I think QUICK REST is good, too.
24:28But in the end, I decided to name it with a plural.
24:32If you add QT and QR, it's 3 to 4, and it's QR.
24:38Unfortunately, my QT wasn't adopted.
24:42At that time, QT Honey wasn't revived.
24:45If Harenchi Gakuen was revived,
24:47would it have spread with the QT code?
24:50Yes.
24:51I miss Harenchi Gakuen.
24:56Despite the hard work,
25:00it was decided to make it a public domain that did not take up space.
25:05Why the great invention of the century?
25:09Today, we recommend a drink with collagen from Morinaga Seika.
25:15Please try it first.
25:18Oh, it's delicious.
25:20Collagen is good for your skin, right?
25:23That's not all.
25:26Everyone, please take a closer look at the package.
25:29Oh, it's not just skin.
25:32It says skin, knee joints, and bones.
25:35Does that mean it's good for your skin, knees, and bones?
25:41That's right.
25:43Skin, knee joints, and bones that have been a concern since the 1950s.
25:48Morinaga Seika's delicious collagen drink, Premium.
25:53Sitting, walking, and other daily movements are important.
25:57The joint cartilage in the knee joint.
26:01More than half of the joint cartilage that acts as a cushion is collagen.
26:08However, collagen in the body decreases,
26:12so there is a sense of discomfort in the movement of the knee.
26:16Morinaga Seika's delicious collagen drink, Premium.
26:21Collagen peptide that is easy to absorb.
26:25It contains 10,000 mg.
26:29In fact, the test results show that it is good for knee joint discomfort.
26:36In addition to collagen, it also contains ceramide, hyaluronic acid, elastin, and vitamin C.
26:45It means that you can get the ingredients that make women happy with this one.
26:52Morinaga Seika, who has been passionate about making sweets for more than 100 years,
26:58is a product that I am confident in its deliciousness.
27:03It's delicious. As expected of Morinaga.
27:06I love this blueberry flavor. It's easy to drink.
27:10If it tastes like this, I can keep drinking it every day.
27:14Skin, knee joints, and bones that have been a concern since the 1950s.
27:19Morinaga Seika's delicious collagen drink, Premium.
27:24Normally, it costs 4,980 yen including tax.
27:29However, as long as you call within 30 minutes after the end of the broadcast,
27:33it will cost 2,000 yen including tax.
27:37In addition, for the first 50 people,
27:42we will add 6 more people and the total will be 18 people.
27:45The price will remain the same. It will cost 2,000 yen including tax.
27:50In addition, Morinaga Seika will pay for shipping.
27:55Please call 0120-010-952 or 010-952.
28:07Morinaga
28:09I love this collagen drink. I will eat it all.
28:14The QR code has gone through a lot of trouble to obtain it.
28:19However, it was decided to make it a public domain that does not take up space.
28:24What kind of implications are there?
28:28Anyone can use the QR code now.
28:31Anyone can print it if they want to make it.
28:33Anyone can read it.
28:35Why is it a system that does not cost money?
28:38Our idea is that a B2B company,
28:44such as Toyota or Honda,
28:47can get development support and make what they want.
28:53At that time, there was no department called marketing or product planning.
28:57At that time, we thought it would be difficult to spread the QR code.
29:03So, we decided to make it a public domain.
29:06Everyone can use it freely and spread the QR code.
29:10On the other hand, the more QR codes there are, the more reading devices are required.
29:14We are good at making things, especially the quality of cars.
29:19So, we decided to open the QR code freely and make it available with a reading device.
29:24It is easy to understand that you can make it available with a QR code,
29:28but if you do that, people will know about it.
29:31If it spreads quickly, people will definitely need to read it.
29:35Another important thing is that it spreads quickly.
29:38In the United States, there is a data market.
29:40If it enters the market, the QR code and data marketing will be divided into two.
29:45I think the profit will also decrease.
29:48So, we decided to make it public by making it full of QR codes as soon as possible.
29:52It is better to make it a de facto standard.
29:55The purpose of spreading the QR code as soon as possible is to make it available for free.
30:02In order not to be devoured by the advanced two-dimensional code,
30:06the transfer was aimed at the registration of the standard of the world, the international standard.
30:13How did they proceed?
30:16In order to make it a standard, it is necessary to make it a standard in the industry.
30:23So, we tried to make it a standard in the industry.
30:28At that time, we were a car parts manufacturer,
30:31so we aimed to adopt it for the car industry.
30:36We adopted it, and from there, the car industry...
30:42Cars are exported to various countries,
30:44such as the U.S.A. and Europe,
30:47and we got the approval of the QR code as the structure of the car industry standard.
30:53From there, we made it a national standard.
30:58In order to be recognized as a standard, it must be necessary in the world.
31:03So, first of all, it was a business for the industry, but it didn't go smoothly.
31:11I was in charge of the distribution of the QR code,
31:14how it was used by customers,
31:16and how it was used in the world.
31:19I joined the company in 1995.
31:22The QR code was released the following year.
31:26At that time, no one knew about the QR code,
31:31and we didn't know how to use it.
31:34We didn't know how to make the code work.
31:36What's more, there was a suspicious pattern of white clothes,
31:40and we started to wonder what it was.
31:43At that time, computers weren't very popular,
31:47so we couldn't show it in the video.
31:51So, we put a bigger one in the suitcase.
31:58Did you bring it one by one?
32:00Yes, I did.
32:01If I wanted to show it in the video, I brought a video deck.
32:05You had to make it work quickly.
32:07Yes, I did.
32:08So, I went around Japan,
32:10and showed them the QR code first.
32:12Then, I asked them how to use it.
32:16I printed a lot of paper documents,
32:19and I showed them all over Japan.
32:22I did it because I was young.
32:24It's hard to get people interested in it at first.
32:26That's right.
32:27However, it was a little different when I showed it in the video.
32:34Did you feel the possibility?
32:36We were the first to know that Kurobe had a hard time.
32:40As I said before, America is advancing,
32:43so there is no way Japan, especially the car parts manufacturer,
32:46can make a code that can be used all over the world.
32:49There was a sense of intrusion,
32:51and I was able to show it to many people and convince them.
32:56I'm grateful that you worked so hard on it.
33:02I feel like my birthday is the same as mine.
33:04I feel like it's my destiny.
33:06Everyone has a connection with their parents.
33:09Their enthusiasm and so on.
33:11In 1997, he was rewarded for his hard-working business,
33:16and he won the Osumitsuki of the International Autonomous Industry Association.
33:21He was building up his achievements,
33:24but the last barrier before registration.
33:27The IOSO is decided by voting in each country.
33:31However, as I said earlier,
33:33the U.S. made one of its own codes,
33:36so it was a countermeasure.
33:39For example, GM adopted a matrix code.
33:43So the IOSO ended up being two.
33:46However, the U.S. only needed one data mouse code,
33:50so they started a negative campaign
33:53to see what the Japanese code was like.
33:56There is such a countermeasure.
33:58At that time, even in a strong country like the U.S.,
34:01for example, even in a small country like Southeast Asia,
34:04one vote is one vote.
34:06So we put Southeast Asia and Asia on our side,
34:09and we got them to agree with us in Asia.
34:12In other words, we got them to start the IOSO process.
34:16As a result, there were more people who agreed with the opposition,
34:20and as a result, it became IOSO.
34:23Democracy has been established properly.
34:26If you adopt one of those codes,
34:29you get a lot of money.
34:32I don't know if it's in the U.S. or somewhere else,
34:35but you might get a lot of money to buy one.
34:38Even so, if you get a lot of votes...
34:41Yes, yes.
34:43You can't say,
34:45I'm a big country, so give me as many votes as you want.
34:48No, you can't.
34:50The QR code has become the world standard
34:53thanks to the efforts of the United Nations.
34:56This project has begun as the development of a new two-dimensional code
35:00for industrial applications,
35:02and has achieved greater success than those involved imagined.
35:06How did it jump out of the factory
35:09and penetrate into our lives?
35:12There are three events that the program has focused on.
35:16The first one is...
35:18The very first event was the mobile phone QR code.
35:23At first, there was no QR code,
35:26but the camera's performance...
35:29That's right.
35:31I've heard the most about the camera's performance,
35:34and it's the lens.
35:36Until then, the cameras on mobile phones
35:39were used to capture scenery and landscapes,
35:42but now they're used to capture distance.
35:45It was difficult to make a small lens that could do both.
35:50So we were able to develop it,
35:53install it, read the QR code,
35:56and take pictures and landscapes.
35:59But...
36:01The QR code is now available on mobile phones,
36:04but if the mobile phone becomes the leader,
36:07it's not very good for telecommunications, is it?
36:10The speed of reading and capturing mobile phones
36:13is completely different from the speed of industrial computers.
36:16I see.
36:18If you do it 10 or 20 times a day for fun,
36:21you can read it on your smartphone or cell phone.
36:24But if you try to read thousands of copies a day,
36:27it's hard on your smartphone.
36:30I see. For B2B, you definitely need a computer.
36:34In the early 2000s,
36:36a mobile phone manufacturer wanted to make it possible
36:39to read QR codes on mobile phones,
36:42so they asked us to provide software.
36:45It was about 20 years ago,
36:48and we were concerned about the loss of technology
36:51and know-how,
36:54and the decline in brand value.
36:57As a result,
37:00we couldn't provide software.
37:03Since we released the QR code specifications,
37:06it was difficult for other manufacturers
37:09to develop software for reading and capturing mobile phones.
37:12However,
37:15the technology developed by Hara and Watabe
37:18was amazing.
37:21The speed of reading and capturing mobile phones
37:24and the ease of reading and capturing mobile phones
37:27were the best in the world.
37:30Of course, the specifications of the QR code are freely available.
37:33But how do you read and capture mobile phones?
37:36Even if you try to read and capture mobile phones,
37:39it's not as good as what DENSO makes.
37:42How do you read and capture mobile phones?
37:45Of course, we know the specifications and technology of the QR code,
37:48so we know that it's easy to read
37:51and capture mobile phones.
37:54That's the strength of DENSO.
37:57You don't say that as a know-how, right?
38:00You can read and capture mobile phones,
38:03but what was the first thing you used to read and capture mobile phones?
38:06There were two things.
38:09One is that
38:12everyone was able to read and capture mobile phones,
38:15so it was popular.
38:18The other is that you can display the QR code on the LCD screen.
38:21I see.
38:24So you don't just read and capture mobile phones.
38:27It's easy to do that, right?
38:30That's right.
38:33Even now, it's easy to display the QR code.
38:36Everyone can read and capture mobile phones.
38:39At first,
38:42I thought about what I could do with NTT DOCOMO
38:45to display the QR code.
38:48I thought about what I could do with NTT DOCOMO
38:51to display the QR code.
38:54I thought about what I could do with NTT DOCOMO
38:57to display the QR code.
39:00But that's the way it is now.
39:03But that's the way it is now.
39:06It's difficult to use other tools
39:09other than the QR code.
39:12It's difficult to use other tools
39:15other than the QR code.
39:18In 2000,
39:21I actually borrowed the QR code from a mobile phone
39:24and bought it.
39:27It took a lot of time.
39:30The phone's display speed is faster now.
39:33The phone's display speed is faster now.
39:36I had to pay in cash.
39:39I had to pay in cash.
39:42I regret it now.
39:45I regret it now.
39:48I regret it now.
39:51If we could realize the potential of this technology at that time,
39:55and if we could display the QR code more clearly,
39:59we could have a service that could change the world later on.
40:04If we could realize that,
40:06we could have gained a lot of share in the electronic payment.
40:10I thought that everyone could use the QR code
40:14because of the airplane I mentioned earlier.
40:17From that moment on, everyone was like,
40:20it's not safe, but it's okay to pay.
40:24At first, it was an unfamiliar technology,
40:27so it was even thought to be suspicious.
40:32But now, it's a big hit in various scenes.
40:37We were able to gain trust from the AMA electronic ticket.
40:42This service, which displays a QR code at the gate,
40:45and allows people to enter without checking in,
40:49was said to be technically difficult.
40:53The most difficult part was that there were various types of machines,
40:57and we had to display the QR code on them.
41:01The brightness of the screen, the brightness of the screen,
41:04and the brightness of the screen, the brightness of the screen,
41:07and the brightness of the screen, the brightness of the screen,
41:10the brightness of the screen, the brightness of the screen,
41:13and the brightness of the screen, the brightness of the screen,
41:16the brightness of the screen, and the brightness of the screen.
41:19It's said that you have to go through 82 gates in one minute.
41:22It was hard to keep up with that speed.
41:26There were also various cell phones,
41:29and more new models were released each year.
41:32Of course, now it's all in the hands of large manufacturers,
41:36but the giant manufacturers released the models from the beginning.
41:39The colors were completely different.
41:41We went to the cell phone manufacturer to buy a cell phone that we didn't even use at the auction,
41:49and we did all the reading and copying experiments.
41:53With the explosive spread of mobile phones,
41:56the QR code has spread to our daily lives,
41:59and has further developed with the establishment of electronic tickets.
42:04The reason why the QR code has spread to the world is because of its popularity.
42:11The origin of the QR code is actually China.
42:16The usage rate of the QR code is more than 80%.
42:19It has recorded explosive hits in Japan, Germany, and France.
42:25Now, the QR code is so widespread that it can be said to be a must-have in the world.
42:31The QR code is so widespread.
42:35How profitable is it for you, Mr. Densho?
42:41First of all, the QR code used there is actually the same as the QR code used in the industrial area and the production area,
42:51and it hasn't been used.
42:54It can be used, so anyone can display it.
42:56Yes.
42:57On the other hand, we develop and provide the reading and copying devices.
43:02For example, if the QR code spread and the number of devices that can be used increases,
43:07I think there will be more opportunities to use our reading and copying devices.
43:12Of course, you are doing a great job, Mr. Densho,
43:15but in a situation where you don't need that much performance,
43:19you can make it if you want to because the specifications are collapsed.
43:22That's right.
43:23For example, in China,
43:25the QR code is so widespread that it can be said to be a must-have.
43:29Unfortunately, our reading and copying devices are almost non-existent,
43:33so there is almost no profit at all.
43:38If you make it a public domain,
43:41isn't there a moment when you think,
43:43if you had done better, you might have made a lot of money?
43:47I'm an engineer, so I'd be happier if they used it all over the world rather than make a lot of money.
43:55In that sense, I think the public domain was the right choice.
43:58If it wasn't for the public domain,
44:01I personally think it would have ended with the Toyota Code that was used in the Toyota Group.
44:07I see.
44:08I'm a salesman, so I make a lot of money once a year.
44:14I wonder if I could have sold more.
44:17But as Mr. Hara said earlier,
44:19if the QR code expands,
44:22I think we'll have more business opportunities.
44:27If the QR code expands in various places,
44:29there will be various use cases that can be used.
44:32For example, hardware, systems, solutions, etc.
44:37I think that kind of thing can be provided.
44:40That's what I'm working on right now.
44:44The QR code, which has been in development for 30 years,
44:49What are the latest use cases?
44:52The air in your room.
44:54Do you know that there are a lot of harmful substances in your room?
44:59For example, bed makeup.
45:01Dust such as dandruff scatters like this.
45:06There are more than 100,000 dandruff in one futon.
45:13These substances will eventually fall to the floor over time.
45:19But every time you walk, you'll end up in the middle again.
45:23Dandruff allergens are found in places about 1 meter or 1.5 meters above the floor.
45:29I think the height of a small child's mouth is about 30 to 50 centimeters above the floor.
45:35There are a lot of allergens there.
45:39I think you should be careful about the air environment.
45:42So, AirDog.
45:45AirDog sucks in clean air from below and emits clean air from above.
45:50So, before it falls to the floor, it is sucked in.
45:54You can clean the air in your room more efficiently.
46:01As a result of the test, you can remove more than 99% of floating dandruff, mold, pollen, and pet allergens.
46:13In addition, you can remove 99.9% of pollen, bacteria, and viruses smaller than PM2.5.
46:24Therefore, more than 12,000 medical facilities around the country have introduced AirDog.
46:32The world's strongest level of air purifier, AirDog, can be purchased from the free trial or official website.
46:40First, search for AirDog.
46:44QRCode
46:52QRCode has been active for 30 years since its development.
46:57What is the latest use case?
47:00I think you can see a train with a QR code on the train door.
47:08It is a QR code used to automatically open and close the train door.
47:16It is a newly developed code.
47:19When the train arrives at the platform, the QR code on the train door is read by the camera on the platform.
47:26Depending on the number and position of the door, the platform door will automatically open and close.
47:34The reason why we started this is because
47:38we used to communicate by train and radio.
47:43But it seems that it costs a lot of money.
47:46It seems to cost tens of millions of yen to remodel a car.
47:50It can be done just by putting a QR code on it.
47:54Also, if it takes a week to remodel a car,
48:00it will take 100 weeks to remodel a car.
48:03It will take two years to remodel a car.
48:06So, we can't do it right away.
48:08We can do it just by putting a QR code on it.
48:11We have been working with the Tokyo Transportation Bureau.
48:15Now, we are working with various railway companies.
48:19Is this different from a normal QR code?
48:22Yes, it is.
48:24One is that it is used at the station.
48:27The other is that it is used at the subway.
48:30It can also be used at stations outside Japan.
48:33For example, if there is a 50% shadow,
48:37you can't read it because it says 30% in a normal QR code.
48:43This QR code is called TQR.
48:46With TQR, you can read up to 50% of Kondo Misaki.
48:51So, no matter what kind of shadow you have,
48:55you can read it scientifically.
48:5850%?
49:00So, if it's a shadow rather than 50%,
49:03it doesn't matter if it's dark?
49:05That's right.
49:06I see.
49:07Also, according to Tokyo Transportation Bureau's request,
49:11if it's a normal QR code,
49:13it's likely to be misled.
49:16So, we want a normal QR code that's famous on smartphones.
49:21You can do a lot of things.
49:22There are still a lot of things you can do.
49:24Yes, there are still a lot.
49:26We can't talk about it, but it's about time.
49:30Thank you for your valuable talk today.
49:33Thank you very much.
49:34Thank you very much.
49:35QR code
49:36QR code didn't have a network at first,
49:41QR code didn't have a network at first,
49:47Lastly, the seeds of the future.
49:50Lastly, the seeds of the future.
49:55Today, we recommend a drink with collagen from Morinaga Seika.
50:00Please try it first.
50:03It's delicious!
50:05Collagen is good for your skin, right?
50:08It's not just that.
50:10Everyone, please take a closer look at the package.
50:14It's not just skin.
50:16It says skin, knee joints, and bones.
50:20Does that mean it's good for your skin, knees, and bones?

52:54It's faster than we thought.
52:56It's like a network.
52:59In January, there was an earthquake in Noto Peninsula.
