One company that has successfully raised pay is a major maker of industrial robots.

03:18

It did this on the back of solid business performance and improved productivity.

03:23

The firm recently unveiled its most advanced machine yet, utilizing artificial intelligence.

03:29

With Japan in the grip of a labor crunch, the firm sees growing demand for such products.

03:36

At its own factory, robots have been sharing the workload with humans for three years.

03:42

The company says that has enabled productivity of workers' to rise by about 40 percent.

03:48

The efficiency upgrade coupled with strong earnings led the company to hike base pay this year by the most ever.

03:57

"The workers are what drive the company."

03:59

"So we aim to increase profits and give back to our employees."

04:06

Behind the push for better pay is inflation.

04:09

Real wages are in fact, still falling, as they are not keeping up with prices.

04:19

That's led the country's biggest labor union organization to demand a pay raise of at least 5 percent in next year's negotiations.

04:28

That's above the 30-year high of over 3.5 percent this year.

04:37

Workers on temporary and part-time contracts are also standing up.

04:41

The so-called non-regular employees account for more than a third of the workforce.

04:48

For the first time this year, they joined hands to request coordinated pay raises.

04:53

Next year, they plan to call for an even bigger increase of at least 10 percent.

04:58

"We urgently need to tackle the issue of how to increase wages for non-regular workers

05:04

and those who do not belong to an organization."

05:07

The momentum is spreading to smaller businesses as well.

05:11

The company that runs this seafood restaurant in south-western Japan streamlined operations by digitalizing its customer information.

05:20

The firm says it has minimized food losses, as data make it possible to purchase materials in just the right amounts.

05:28

That's created an opportunity to open a specialty take-out store.

05:32

Higher profits have allowed it to raise pay by an average of 5 percent.

05:38

"Even with a small company like ours, if you try seriously, your efforts will have positive results."

05:45

A leading economic researcher says raising pay is the way to go in times of labor shortage.

05:53

"We need well-equipped factories, but also great human resources to produce high-quality products."

06:00

"In these times, businesses need to increase wages to be able to hire such people."

06:07

Japan has long been trying to kick-start a self-sustaining cycle of higher wages and robust spending.

06:13

It may be now at a critical juncture for doing just that.

09:00

In November, a hotel in the western Japanese city of Osaka introduced a unique service.

09:07

"This is a special room where our customers can sleep in supreme comfort."

09:13

The hotel provides an ergonomic pillow and a room aroma of forest scents.

09:22

Books are a key ingredient for getting a good slumber.

09:27

"We choose books that don't have dramatic plots, and which create a feeling of warmth after reading them."

09:35

The point is not to choose books to make you fall asleep instantly, but those that put readers into a good state of mind.

09:45

The project was started by a major book distributor.

09:48

It chooses a selection of comics and short stories for hotels.

09:55

"I hope we can help people build the habit of reading a book for 10 minutes before going to sleep."

10:03

Meanwhile, a company that sells wood and interior fittings has developed a unique nap capsule

10:09

in which a person can sleep in an upright position.

10:17

The interior provides support to the shins and buttocks.

10:24

It is said that people do not fall into a deep sleep while upright, and can get back to work immediately after waking up.

10:32

The company has been working with a university to study the capsule's benefits.

10:39

"My brain didn't shut down."

10:41

"But I felt like I was able to rest my body."

10:45

The company expects the product to appeal to airlines, hospitals, and other places where employees work at night.

10:56

"The norm is to resist the urge to sleep while working."

10:59

"But it would be good if society could accept the idea of people napping during work

11:03

because workers' productivity would improve after resting."

11:08

The average sleep time for people around the world is 8 hours and 28 minutes.

11:14

That is over an hour more than for Japanese people.

11:21

A major chemical firm decided to make use of a program to improve sleep.

11:28

Employees volunteered to wear a device attached to a wristband.

11:33

It measured the amount of time they were asleep and awake, as well as the quality of their sleep.

11:40

Using a service to analyze the data,

11:42

the company gave tips to employees on their habits during the day and before going to bed to optimize sleep quality.

11:51

"I felt the need to improve the quality of my sleep, and decided to follow their advice."

11:56

"I'm now able to wake up refreshed in the morning."

12:01

"I hope to increase the number of people who say they are sleeping sufficiently

12:05

so they can enjoy their jobs and work with a sense of accomplishment."

12:10

Getting enough quality sleep may be essential to surviving in today's hectic world.

12:15

And it's no longer just bedding companies trying to fill this need.

12:20

All kinds of others, from hotels to manufacturers, are waking up as well.

14:01

By making a few more deifications, standard diesel engines, can now run on hydrogen.

14:09

And aluminum waste can now be used to produce hydrogen through a chemical reaction that results in zero CO2 emissions!

14:17

Today's On-Site Report shows how some companies are overcoming the main issues

14:21

that have prevented hydrogen from catching on as a clean source of energy!

16:35

Clean hydrogen is now becoming a leading option in the current push toward decarbonization.

16:43

This vehicle produces zero CO2 emissions, the only thing that is coming out the exhaust, is water vapor.

16:52

This delivery truck is powered by an engine that runs on 100% hydrogen.

16:58

Almost all hydrogen powered vehicles in use today are fuel cell electric vehicles

17:03

that use hydrogen to generate electricity which is then used to power an electric motor.

17:12

This truck however, is powered by a combustion engine that was modified to run on hydrogen instead of diesel.

17:22

This is research facility belongs to a company that specializes in hydrogen fuel applications.

17:29

The company thought that if hydrogen could be used to power delivery trucks, it would help drastically reduce CO2 emissions.

17:41

Since carbon emissions are clearly the enemy,

17:45

we felt the quickest and most effective way to eliminate them

17:49

would be by converting diesel engines so they can run on hydrogen.

17:55

The biggest advantage of engine conversion is it requires only replacing a small number of components.

18:01

The pistons need to be replaced in order to withstand the increased explosive force of hydrogen.

18:07

A new cylinder head which can accommodate spark plugs, which aren't used in diesel engines, must also be added.

18:13

A hydrogen fuel injection system and a new intake manifold are also needed.

18:21

Lastly, fuel injection levels are adjusted to prevent combustion damage from the hydrogen,

18:26

which has a higher energy output than diesel.

18:32

Equipped with four hydrogen tanks, which are also used in FCEVs, the truck can travel 200 km before needing a quick fill up.

18:48

Only requiring new fuel tanks and modifications to about 30% of the engine,

18:53

allows for a quick and affordable conversion process.

18:57

It's not limited to big trucks with diesel engines,

19:01

we can convert anything with a combustion engine so it can run on hydrogen.

19:06

In November of 2023, the research and development team began working with a logistics company to test out its modified engines.

19:14

Many logistics companies are looking at engine conversion as one of the most viable options for decarbonization.

19:23

The pressure to cut CO2 emissions is also coming from the client side,

19:27

so if we can switch to engines that run on hydrogen, that will help us to stand out from the competition.

19:33

Once testing is complete, the developer plans to partner with auto parts manufacturers

19:37

to mass produce the conversion components in 2024.

19:43

It hopes to convert more than 20,000 trucks to using hydrogen fuel by 2050.

19:51

We want to create a society where hydrogen use is the norm, rather than the exception.

19:56

Once we get this truck engine done right, demand will expand and our business will grow.

20:02

I think the key to our success will be in modifying hydrogen engines for medium-size and large-size trucks, generators, and trains.

21:37

The open-air hot spring baths at this inn located in Toyama prefecture are proving to be popular with guests.

21:44

Hydrogen is used to ensure the water stays at comfortable bathing temperatures.

21:49

Outside the inn, you'll find a hydrogen production system and a water heater.

21:57

What really makes the system standout, is the fact that it's powered by "clean hydrogen"

22:01

made through a unique process that produces no CO2 emissions.

22:08

The key material used to produce the hydrogen is aluminum that is sourced from waste products.

22:18

Producing hydrogen on-site, provides access to an eco-friendly energy source

22:22

without requiring additional transportation or storage costs.

22:28

Mizuki Nobuaki developed the special equipment used to produce hydrogen from waste aluminum.

22:35

He first became interested in the aluminum that is attached to many types of plastic and paper waste about 17 years ago,

22:42

when he was in charge of recycling at a logistics company.

22:48

For example, the aluminum foil used in food packaging is difficult to separate and collect, so it's not recycled.

22:55

The amount of waste containing aluminum accounts for 10% of household garbage.

23:02

Like much of the world, most of this kind of garbage is disposed of in landfills or is incinerated.

23:08

I thought this was such a waste and thought it would be amazing if we could find a way use it as a source of energy.

23:16

To turn his dream into a reality, Mizuki teamed with researchers at a nearby university and began to do research.

23:23

The first step was figuring out how to best separate aluminum from the waste products.

23:28

Next, he came up with a process that uses high temperatures to burn away other contaminants, resulting in highly pure aluminum.

23:37

The final step was to develop a method to efficiently produce hydrogen from aluminum.

23:41

He decided to base his process off of techniques developed by a team of researchers from a Spanish university.

23:48

After 10 years of research and development, Mizuki finally perfected a special formula.

23:54

The unique formula allows for a continuous reaction between water and aluminum that results in the production of hydrogen.

24:06

Once the process is finished, the remaining chemical liquid can be filtered and used again.

24:18

Just 50g of aluminum waste can produce enough hydrogen to power an FCEV for 1km.

24:27

So far, Mizuki‘s company has received inquiries for his aluminum-based hydrogen production systems

24:32

from more than 10 hotels and inns that want a more eco-friendly way to provide their guests with hot water.

24:38

He currently plans to begin sales sometime in 2024.

24:44

The current trend is toward decarbonization and reaching zero emissions,

24:49

so I think it would be great if we could use this type of technology

24:52

to create eco-friendly hydrogen and do our part in this great time of transition.

25:00

We can produce green hydrogen from aluminum which is in abundant supply almost everywhere,

25:05

and that would otherwise just end up in a landfill.

25:08

This type of energy is just the sort of option we need in order to get away from oil and other types of fossil fuel.
