00:00Today's Gatchiriman Day is the heavy industry of the Reiwa era!
00:09In the height of the Showa era, the main industries of Japan were heavy, thick, long, and large.
00:16These industries were called the heavy industry.
00:19These industries were called the heavy industry.
00:23These industries were called the heavy industry.
00:26Light and small, such as電卓 or Walkman,
00:30Light and small, such as 電卓 or Walkman,
00:34Light and smart!
00:36This was the home game of Japan for a long time.
00:39However, it seems that the heavy industry of the Reiwa era has revived again.
00:46How much is the sales?
00:48About 1.9 billion yen.
00:49About 1.9 billion yen.
00:50About 1.9 billion yen.
00:51About 1.4 billion yen.
00:52About 1.4 billion yen.
00:54If the scale is big, the sales are also big!
00:58So today, we will cover the heavy industry of the Reiwa era in detail!
01:03A super-huge ship that is indispensable for the bridge construction of Japan, which has a strong reputation!
01:08Most of the big bridges in Japan are on this ship.
01:12The huge ship that supports the construction of the Japanese sea was amazing!
01:18Last year, KABUKA entered the best-selling company in Japan!
01:23It has increased by more than 100 times in a year.
01:26Really?
01:27It's like Reiwa, and it's selling like crazy!
01:31Today's Gacchiri Monday is the heavy industry of Reiwa!
01:35We will reveal the secrets of the heavy industry of the Reiwa era!
01:41Good morning!
01:43Today is the heavy industry of the Reiwa era!
01:45I heard this word for the first time.
01:47Me too.
01:49When I think about it, Japan was like that.
01:51It was a country that was trying to make money by exporting it.
01:54It was changing more and more, but now the heavy industry is making money and going to a new stage.
02:00I want to live my life as a heavy industry.
02:02Certainly.
02:03Let's take a look!
02:05Good morning!
02:07The heavy industry of the Reiwa era has begun!
02:10Let's go!
02:23It's probably a little scary size as a living thing.
02:26That's right.
02:30This is amazing technology.
02:34That's amazing.
02:37Gacchiri!
02:38Let me introduce today's guests.
02:40Economic analyst Kohei Morinaga and Hikaru Ijougi.
02:44Good morning!
02:48It's the heavy industry of the Reiwa era.
02:50There are four of them.
02:51You got them all.
02:54It's probably a little scary size as a living thing.
02:57That's right.
02:59It's interesting.
03:00The heavy industry is the theme of today's Gacchiri Monday.
03:04Business is like a pendulum.
03:07Originally, Japan was good at heavy industry.
03:09For example, we were good at iron and wire.
03:13Since the 1980s, small and delicate things, such as semiconductors and home appliances, have become popular.
03:20The pendulum is back here.
03:22What's added here is that it's delicate and heavy industry.
03:26Oh, I see.
03:27That's where the technology comes in.
03:29In that sense, it's the time when Japan is the best at both sides.
03:34I see.
03:35The heavy industry of the Reiwa era.
03:37First of all, 15,000 tons and 1.5 billion yen.
03:40A super-huge thing will appear.
03:43The first one to come was the Yorigami Construction Company in Kobe.
03:49Yorigami Construction.
03:50How much is the sales?
03:52Last year, it was about 1.9 billion yen.
03:551.9 billion yen?
03:57Gacchiri!
03:59Yorigami Construction is making a lot of money.
04:03It's the largest in Japan.
04:06The largest in Japan.
04:08It's making a lot of money.
04:11So we came to Higashiharimako in Hyogo Prefecture.
04:16What kind of big thing is there?
04:21Wow, it's huge.
04:24What appeared was a huge piece of iron that I don't know what it is.
04:30That's the Kijikusen Kaisho.
04:32Is that a ship?
04:34It's a crane ship.
04:35A crane ship?
04:36Yes.
04:37This is the huge crane ship Kaisho, which Yorigami Construction is proud of.
04:42It's amazing.
04:43The size is 120 meters long and 55 meters wide.
04:48It has a capacity of 15,000 tons.
04:50It's the largest in Japan.
04:52It has to be heavy.
04:53The price of one ship is about 1.5 billion yen.
04:58What are they going to do with this huge crane ship?
05:03It's a ship that carries huge things.
05:06The easiest way to understand it is to catch a horse.
05:09You can also pull up a ship that sank into the sea.
05:13This Kaisho can carry up to 4,100 tons of things with two 150-meter-long cranes.
05:24But why does it have to be so big?
05:28If you want to build a bridge, it's better to bring a finished one.
05:32That way, you can reduce the time and cost.
05:36It's quite difficult to build a bridge on site.
05:42So, they made a bridge in another place and carried it.
05:50Until now, Akashi Kaikyo Bridge, Rainbow Bridge, etc.
05:55Yorigami Construction has built many big bridges and one-way streets in Japan.
06:03But if you lift such a heavy thing from the sea, won't it sink or tilt?
06:10Normally, that's what happens, but Kaisho is fine.
06:13Why?
06:14The secret is in the inside of the crane ship.
06:18Let's go to Kaisho.
06:20It's amazing. It's one block from the edge of the ship.
06:22We were guided to this room.
06:25What is this for?
06:27This is called a ballast device.
06:30It's a device to put seawater in and tilt the ship.
06:35Inside Kaisho, there are 11 huge empty tanks.
06:40This is a mechanism that won't sink even if you lift a heavy thing.
06:46However, if you lift a very heavy thing like a bridge, the ship will tilt.
06:53So, in order for the ship to be horizontal when you lift it,
06:59you put seawater in the tank on the other side of the crane and tilt the ship in advance.
07:06So, Kaisho, which is about to depart, is tilted about 5 degrees.
07:12Everyone lives here.
07:14If you tilt your head down, blood will come up.
07:19All the rooms are designed so that blood won't come up.
07:25By the way, this is the inside of the tank where seawater is put in.
07:30There is seawater in it.
07:33But how to put this water in is really delicate and difficult.
07:38Because...
07:39If you put seawater in the shallow part, it will stick to the bottom and the ship won't move.
07:44That's right. When you work on a crane in the shallow part,
07:48if the ship tilts even a little, it will get stuck.
07:52Therefore, it seems really difficult to keep the ship horizontal at first,
07:56and to put seawater in the tank at the same time while lifting the thing,
08:02and to keep the ship horizontal until the end.
08:07The next stop is the operation room at the heart of the ship at the base of the crane.
08:14Excuse me.
08:16I'm the captain of this ship.
08:18Oh, captain.
08:19Yes.
08:20This is Kaisho's captain Matsubara.
08:22What is his number one job?
08:25It's mainly crane operation.
08:27The captain's job is crane operation.
08:30So, the cockpit is completely different from the ship.
08:34There are a lot of levers here.
08:36What kind of levers are these?
08:37These are the levers that move the winch.
08:39Winch?
08:40What is a winch?
08:41A winch is a winch.
08:44If you don't know what a winch is, you'll be in trouble.
08:46No one in this industry knows what a winch is.
08:48What is a winch, which is too obvious for Captain Matsubara?
08:52It's a device that rolls up and down the wires at various points of the crane line.
08:59It's controlled by a 19-inch lever in the operation room.
09:04But it's huge, so it's very difficult to lift it up.
09:10Onagawa-cho, Miyagi Prefecture.
09:14Kaisho was dispatched to hang this 240-meter bridge.
09:20How did he carry such a huge bridge?
09:26First of all, it takes a few people to connect the bridge and the crane with wires.
09:32It takes three days to connect 32 wires to the bridge.
09:39When the bridge is finally lifted,
09:42it takes a few more days to move to the place where the bridge is installed.
09:48When the bridge arrives at the site,
09:50it is fixed with wires to prevent the crane line from moving.
09:56It's finally time to install the bridge.
10:00It's the most difficult part.
10:04This is the biggest challenge.
10:07The bridge is 240 meters long.
10:09If the bridge shakes, the left and right senses will be different.
10:13If you don't adjust it properly, you can't install it.
10:17So, how do you fix the bridge?
10:23He used the wires to move the ship to the left and right.
10:30And he moved the bridge to the rest position.
10:34However,
10:36Captain Matsubara can't see this work well, so it's very difficult.
10:41He moved the ship by radio signal.
10:45It's 2 centimeters.
10:53It's like a team play.
10:59It took two hours to install the bridge.
11:05The bridge is installed.
11:08It takes two days to install the bridge.
11:12It's very fast.
11:13The bridge is installed.
11:15The bridge is installed.
11:17The bridge is installed.
11:19It's very difficult to move the bridge in two centimeters.
11:23But it can reduce the cost of the bridge and save time.
11:29The bridge was originally used to pull up the sunken ships.
11:36You may have seen the video of the sunken ships in the Great East Japan Earthquake.
11:41The bridge was originally used to pull up the sunken ships.
11:48Next, we visited a company in Kasaoka City, Okayama Prefecture.
11:52It's called JFE Engineering.
11:55I'm Kokuryu.
11:57Kokuryu, how much does it cost?
12:00It costs 5,400 million yen.
12:05This is the difference.
12:07What is this heavy object?
12:11This is it.
12:13It's a huge pipe.
12:18It's called a monopile.
12:21It's the root of a wind turbine.
12:24This is the root of a huge wind turbine.
12:32The pipe is 60 meters long, 10 meters in diameter, and weighs 2,500 tons.
12:38It's a huge pipe.
12:41Kokuryu, isn't the top wing more important than the wind turbine?
12:47The root is important.
12:49A wind turbine is the root of a wind turbine.
12:53It stands on the sea.
12:55If the root is not solid, it will be difficult.
12:59JFE is building this part of the wind turbine that stands on the sea.
13:04The wind turbine is getting bigger and bigger.
13:08There are more wind turbines than Tokyo Tocho.
13:13The bigger the wind turbine, the more efficiently it can generate electricity.
13:16The wind turbine is getting bigger and bigger.
13:20The root of the wind turbine must be big, too.
13:24Kokuryu, how much is this?
13:29I can't buy it even if I win the Masters.
13:35Why the Masters?
13:37Because I love it.
13:40If you look up the prize money of the Masters, it's more than 5.5 million yen.
13:45That's a lot of money.
13:48Let's go inside the factory to see how they make it.
13:53It's so big.
13:57This is the iron plate used for the root of the wind turbine.
14:01Iron plate 30m x 4m.
14:05How do you make it?
14:07Roll it up and make a ring.
14:10It seems that this iron plate can be rolled up and made into a ring and connected several times.
14:16But how do you roll it up?
14:19This is called a bending roll.
14:23This is a machine that rolls the iron plate up and down.
14:29We've introduced similar machines on the show before.
14:34But the size is a little different.
14:38First, set a huge iron plate.
14:43The four of them roll the iron plate up and down carefully and slowly.
14:54And the difficulty of bending is...
15:00The iron plate is big and heavy, so it bends while bending.
15:06That's right. It's huge, so it bends.
15:11It's very difficult to support it with support and bend it while balancing it.
15:17In the end, you have to make a beautiful circle without distortion.
15:23But if you bend it too much, you can't get it back.
15:28It's a very delicate job.
15:30The thickness is slightly different.
15:32It's a very difficult process because it depends on the habits of each iron plate and the skills of the workers.
15:41And...
15:46It's finally done!
15:49A giant ring with a diameter of 10 meters and a surface area of twice the size of sumo.
15:56Next, we'll weld and attach the joints of the rings.
16:01Bring the joint to the top.
16:05It goes up to a height of 10 meters.
16:09Start welding!
16:12Wait a minute!
16:14The sparks aren't coming out much.
16:17Are you already welding?
16:20Yes, I'm welding now.
16:23I'm doing it in a completely different way from welding you see at ironworks.
16:28This is a special welding method called submerged arc welding.
16:35In order to quickly and firmly attach a thick iron plate,
16:40make a groove in the iron plate and pour iron into it to weld.
16:47This welding requires skilled skills because the material and temperature of the day differ in how to weld.
16:55If you can make a ring,
16:58you can attach as many as you want and make it longer.
17:02How long will it be?
17:04There are four pipes here.
17:06If you connect them, you can make a giant windmill with a diameter of 100 meters.
17:09So we connect them at the site, right?
17:11We'll connect this ring and make it as long as 100 meters.
17:17Will the giant windmill be able to sell in the future?
17:20Will it be sold?
17:22The government is trying to increase wind power,
17:26so we plan to build more than 100 windmills a year.
17:31100 windmills a year!
17:33It looks like it's going to make a lot of money!
17:36JFE Engineering is the root of windmills,
17:39and it's going to make a lot of money in Japan!
17:43It's a little unusual for it to be that big.
17:47But when welding,
17:50the basic feeling is like this,
17:53so it's a human delicacy.
17:56Will you be able to carry all the welding?
18:00Even if it's about 100 meters,
18:03there will be a dedicated ship to carry it,
18:06and we will soon be able to carry it to the wind power site.
18:10So you're going to build a factory near the sea and be able to carry it right away?
18:13Yes, that's right.
18:15The next factory we visited is in Sakura City, Chiba Prefecture.
18:19It's a company called Fujikura.
18:22This is the president, Mr. Yamanaka.
18:25Please get in.
18:27The factory is 10 times the size of the Tokyo Dome,
18:31so there will be a dedicated bus to carry it to the wind power site.
18:34I have a very good feeling about this.
18:38How old is the factory?
18:40It was built in 1923.
18:43And...
18:45This is the company that has the highest stock price in the past year.
18:49That's amazing.
18:51This company, Fujikura,
18:54has been stable for 140 years,
18:58but last year it suddenly exploded.
19:01It rose to 60,000 yen in a year.
19:0460,000 yen?
19:06That's amazing.
19:08That's because Fujikura's heavy-duty products are very popular right now.
19:15Why is that?
19:17Let's follow Mr. Yamanaka.
19:19What appeared was...
19:22Oh, it's a huge thing that looks like a string.
19:26What is this?
19:28It's this.
19:30What is this?
19:32It's a light fiber cable.
19:33What is this?
19:35It's a light fiber cable.
19:37Light fiber is a string that sends a lot of data, not electricity.
19:43Because this cable is now being used in the power lines and underground,
19:48the internet in Japan is getting faster and faster,
19:51so you can watch videos on your smartphone or computer.
19:56Fujikura's light fiber cable can send a lot of data,
20:01and now that it's in the AI boom, it's in the digital industry,
20:05and now it's six times more expensive.
20:09And Fujikura can make this for a long time.
20:13It can be made several thousand kilometers at once.
20:16Several thousand kilometers?
20:20It's as long as Hawaii from Tokyo.
20:23We asked him to show us how to make the long light fiber.
20:28And...
20:29I've never seen anyone make light fiber.
20:32This is the process of making a lump of glass.
20:35Light fiber is made of glass?
20:38Yes, it's made of transparent glass.
20:41Yes, light fiber is made of glass.
20:44And it's made of super-transparent glass with no impurities.
20:48So the way glass is made is also unique.
20:52Normal glass is formed by dissolving raw materials,
20:56but what about light fiber glass?
20:59The raw material of the glass is in the flame,
21:02and the glass is made artificially by chemical reaction.
21:05I don't know what you're talking about.
21:07The glass itself is turned into a flame, and is blown to harden it.
21:11That's why no impurities get in.
21:14This is the lump of glass that took a few days to make.
21:20Wow, it's so transparent.
21:23Yes.
21:25Let's take a look at the cross-section.
21:28There's a core in the middle, right?
21:31Yes, that's right. The light goes through this core.
21:35The light goes through the core?
21:38Let's explain the principle of light fiber in this experiment set.
21:44If you make a hole in a transparent container and shine light from the back,
21:48the light will go through the hole and hit the wall straight.
21:54But if you put water in the container,
21:58the light will also fall along the water flowing from the hole.
22:04The light hits the edge of the water and reflects in the water.
22:11The principle of light fiber is the same as this.
22:14The same principle.
22:16The light goes through the core of the two types of glass,
22:20and it reflects and flies far away.
22:24By the way, how long can you make light fiber from one piece of glass?
22:31About 2,000 to 3,000 kilometers of light fiber can be made.
22:35That's amazing.
22:37With this one piece of glass, you can make it long enough to reach Tokyo to Manila, the Philippines.
22:41Then, how can you make such a long piece of light fiber?
22:50How can you make 3,000 kilometers of light fiber from this piece of glass?
22:56We came to the top of this slightly tall building.
23:02This is the device to make light fiber from the piece of glass.
23:07It's made by this machine.
23:10Then...
23:16Something is falling from the machine.
23:21It's falling down. What is this?
23:25It stretches a piece of glass like this.
23:28It's gravity.
23:30Actually, this is a piece of glass.
23:33It melts by heat and stretches by gravity.
23:37I think it's quite primitive.
23:49I can't tell you in detail,
23:52but it melts a piece of glass from a high place in the building and shrinks it.
23:59In the end, it becomes 0.1 mm thick.
24:03If you cool it at the bottom and wrap it, it becomes 3,000 kilometers long.
24:11Why do you have to make it so long?
24:14By making it so long, you can put a lot of light fiber in a thinner cable.
24:20If you put a lot of thin light fiber than one thick light fiber, you can send a lot of data.
24:27That's why they are working hard to make it thinner.
24:30In addition, there is such a great technique to load the light fiber.
24:35In the past, it was in the form of a ribbon.
24:40In the past, the light fiber was put in the cable in the form of an obi.
24:47Fujikura...
24:49Do I pull it like this?
24:51It's completely different.
24:53That's the structure.
24:55When you load the light fiber, you can change the shape and load it.
25:01Because you can change the shape?
25:03It can be loaded without gaps, so it contains more than 13,000 times more than usual.
25:09I see.
25:11Finally, I would like to ask Mr. Kouhei.
25:14Mr. Kouhei, please tell us the recommended heavy industry.
25:17That's after CM2.
25:19Please tell us the recommended heavy industry.
25:22That's the Super Resin Industry.
25:25What kind of company is it?
25:27FRP.
25:29FRP?
25:31It's a fiberglass plastic company.
25:34There was a tower of the sun.
25:37There was a face of the sun.
25:39That's exactly what fiberglass plastic is made of.
25:43It's a company that made it.
25:45First of all, it's light and durable.
25:47It's light, durable, and fiberglass, so it's not rusty like metal.
25:53It's a company that will be the cornerstone of the heavy industry in the future.
25:58It's a company that can make light and big things.
26:01That's right. And it's strong.
26:03It's a business where you can try too much.
26:05The toys of the toy shop are all free to try.
26:08No wonder it's so popular in the car shop.
26:10If you sell all the stores that are free to try,
26:13It's four times the sales.
26:15I didn't know there was such a thing.
