Hello, and welcome to Japanology Plus.
I'm Peter Barakan.

00:20

Our theme for today is washing machines.

00:23

Laundromats and dry cleaners
are ubiquitous in Japan,

00:27

but almost every household
has a washing machine,

00:30

and many people make use of
theirs on a practically daily basis.

00:34

This has led to the development of
really high-tech washing machines,

00:38

with a multitude of functions.

00:41

And some five million of them
are sold just in Japan every year.

00:45

You can see some of the latest
models behind me here,

00:48

and on today's program

00:49

we'll take a look at the evolution
of Japanese washing machines,

00:53

from the very early days,
all the way up to the state of the art.

00:58

Washing Machines

01:04

Washing machines seem to have evolved

01:07

in different ways
in different parts of the world,

01:10

depending on history, customs,
and household conditions.

01:19

In Europe, front-load washing
machines are common.

01:23

A spinning drum repeatedly lifts
and drops the laundry with a thump.

01:33

And it seems that a striking action

01:35

has been part of laundry culture
in Europe since Roman times.

01:42

Front-load washers are a modern
take on that tradition.

01:47

A different technique was
widely adopted in the USA:

01:51

a tub of water was heated over a fire,

01:54

and laundry was swirled
around with a stick.

01:58

The modern equivalent of that
is the agitator washing machine,

02:03

with a rod in the middle.

02:06

In Japan, meanwhile,
impeller washing machines are common.

02:11

A rotating device at the bottom of
the drum creates a strong flow of water.

02:19

This echoes the old practice
in Japan of washing clothes in a river.

02:25

Japanese washing machines
recreate that tradition.

02:31

Japanese washing machines
are now among the most

02:34

technologically advanced in the world.

02:41

Hello.

02:43

Something tells me you
must be Fujiyama-san.

02:45

Yes, I'm Fujiyama. Hello!

02:48

- Nice to meet you.
- Nice to meet you.

02:50

Our guest is Fujiyama Tetsuhito,
a household appliance expert.

02:57

He professionally reviews them,

02:59

describing their functionality,
ease of use, and even shortcomings.

03:08

First, he takes us to
a major electronics store.

03:14

Not all that long ago,
we bought a new washing machine.

03:17

And you come to these big shops,

03:18

and there is so many different types.

03:20

Just navigating your way through
this jungle of machines takes forever.

03:26

Don't worry, I'll be your guide.

03:29

In Japan, we have top-loaders.

03:31

Yep.

03:32

Nationwide, they account for
70 percent of all washing machines.

03:37

- That many?
- Yes.

03:38

So let's say you've made up your mind.
You're going to go for a top-loader.

03:42

There are all these different types,
so how are you going to choose?

03:46

There are lots of functions.

03:49

You should look for
the ones that suit you.

03:52

OK.

03:53

Shall we look at some examples?

03:54

Yep.

03:55

First...this one.

03:58

Ultrafine bubbles.

03:59

What's that?

04:00

Let me explain.

04:01

Detergents produce foam
that gets the laundry clean.

04:06

But this machine produces
exceptionally small bubbles.

04:11

These tiny nano-bubbles
can get rid of dirt or oil

04:14

lurking deep in the fibers.

04:17

You know how a white shirt
will go yellow-ish

04:19

if you don't use it for a while?

04:22

I don't wear very many white shirts,

04:24

but I know what you're
talking about, yeah.

04:26

This function helps to keep shirts white.

04:30

Ultrafine bubbles get right between
fibers to remove dirt and grease.

04:36

So a white shirt will not turn yellow,
even if it's set aside for a year.

04:45

This technique was developed in Japan.

04:49

And Japanese machines have
various other unique functions.

04:53

Like?

04:54

A “bathwater” feature, for example.

04:58

You probably won't see this anywhere else.

05:01

In Japan, a bather gets clean
outside the bathtub,

05:04

then simply soaks in the bathwater,
which stays clean.

05:09

The bathwater feature lets
you re-use that water.

05:13

Top-loading machines use
70 to 80 liters of water.

05:18

Quite a lot!

05:20

But that's roughly how much
you need to fill a Japanese bathtub.

05:25

This feature echoes when
people used to conserve water

05:29

by pouring bathwater into
early washing machines.

05:35

OK.

05:37

So these new machines
inherit that tradition.

05:42

Front-loaders are
a popular choice worldwide.

05:46

They too feature various
Japanese innovations.

05:51

These ones incorporate AI technology.

05:55

They weigh the laundry you put inside.

05:58

Right.

05:59

They automatically add detergent.

06:03

Then they detect how dirty the laundry is,

06:06

and adjust the washing time.

06:09

How do they sense how dirty
or not the clothes are?

06:13

They measure the water's transparency.

06:17

And then...let's say the dirt is stubborn.

06:21

It isn't washing away,
and the water isn't turning clear.

06:26

The machines will add more time,
and keep washing.

06:31

They're really smart.

06:34

The machines can be
connected to your phone.

06:38

That way you can check on progress
and see when the laundry will be done.

06:45

Japanese front-loaders take care of
everything from washing to drying.

06:51

The highlights include a special feature
that makes the laundry itself look great.

06:57

With a regular front-loader,
shirts end up with lots of wrinkles.

07:04

Yeah, of course.

07:06

With these machines, they look ironed.

07:09

And how do they do that?

07:11

By applying a large volume of air.

07:14

That's how they do it.

07:16

Imagine pulling your wet clothes
taut with your bare hands.

07:22

That's what the machine can do.

07:24

Moving on... some clothes are waterproof.

07:29

Skiwear, and so on.

07:31

Oh, yes.

07:32

Eventually, they stop repelling water.

07:36

It starts to soak in.

07:38

Right.

07:39

The ability to repel water
is called “the lotus effect.”

07:44

A lotus leaf is covered
in countless protrusions.

07:48

Water cannot seep in.

07:50

Droplets just roll off the surface.

07:53

With water-repellent clothing,
tiny hairs function in the same way,

07:58

but their condition
deteriorates over time.

08:01

This washing machine restores
the water-repellent qualities

08:05

of the clothing's surface.

08:06

Do you know how it does that?

08:08

Well, it heats the clothes
at a certain temperature.

08:14

The hairs are restored
to their former position,

08:17

and once again they can repel water.

08:21

That's how it works.

08:26

We asked a salesperson which
features are in demand in Japan.

08:32

This automatic input
system is quite popular.

08:37

You fill the containers with
detergent and fabric softener.

08:41

Then the machine itself decides
how much to use,

08:45

depending on the amount of laundry.

08:51

Around the world,

08:52

the history of laundry is as long
as the history of clothing itself.

09:00

In Japan, in the centuries
before detergent,

09:03

clothes were mainly washed
by hand, in a river.

09:09

In the 8th century,

09:12

people began using bean pods
and berries as a rudimentary detergent.

09:18

These ingredients generated foam
that had a cleaning effect.

09:25

In the 16th century,
soap arrived on ships from Portugal.

09:31

It was a luxury commodity, though,
available only to the ruling elite.

09:41

Most people back then were washing
their clothes using plant extracts, lye,

09:46

and the water left over from washing rice.

09:55

In modern times, washing machines
evolved quickly in the West.

10:00

They made a significant impact
on everyday routines.

10:05

In 1908, the world's first electric
washing machine was launched in the USA.

10:12

Here it is.

10:13

Fourteen years later,
it was imported to Japan.

10:19

Its advantages were noted
and research began.

10:24

In 1930, Japan's first electric
washing machine went on sale.

10:30

But it cost the equivalent of six
months' wages for an office worker.

10:36

It was far too expensive for most people.

10:41

In the West, laundry habits
were changing rapidly.

10:45

But in Japan, most people still
washed clothes by hand,

10:49

using a washboard and a tub of water.

10:53

That was hard work.

11:00

It wasn't until the 1950s

11:02

that Japanese companies began
focusing in earnest on electric models.

11:09

They tried to outdo each other,
and competition was fierce.

11:15

Prices dropped dramatically and more
people could now afford a washing machine.

11:22

The hard work of washing clothes by hand

11:25

finally started to become
a thing of the past.

11:31

Rectangular machines were
both effective and compact,

11:35

perfect for Japan's relatively
small homes.

11:39

They were a huge hit.

11:43

The washing machine joined
the television and the refrigerator

11:47

in a trio of must-have household
items for the whole nation.

11:54

To find out how modern Japanese
washing machines are made,

11:58

we're off to a state-of-the-art factory.

12:03

Let's dive into the drum!

12:10

These factory assembly lines are really
fascinating to watch, aren't they?

12:14

Yeah.

12:15

So this is the drum from the front-loading
washing machine, yeah?

12:19

Right. It's the drum.

12:21

They're actually made over there.

12:24

Shall we have a look?

12:25

Sure.

12:33

Here comes a drum.

12:34

The surface is flat, right?

12:39

It's then pressed to generate
a diamond pattern.

12:42

Yeah!

12:44

You see it?

12:46

That strengthens the drum,

12:47

and makes the washing
process much more effective.

12:52

Why does the diamond pattern
make the washing more effective?

12:57

It rubs against the laundry.

12:59

Oh, OK.

13:02

Many people living in Japanese
apartments and condominiums

13:05

strive to be good neighbors.

13:09

And noise can be a source of complaints.

13:14

This is the base of the machine.

13:17

Oh right, OK.

13:19

In Japan, many washing machines
are used in apartment blocks.

13:24

They need to operate quietly.

13:26

And so they're equipped
with a suspension system.

13:29

Like in a car.

13:31

Oh that's what these things are?

13:33

So when it's doing the spin
drying and it shakes a lot,

13:35

that's where these things kick in?

13:37

The drum we saw earlier is attached here.

13:40

It hangs down on two springs.

13:43

It's just like a car's suspension.

13:45

It's the same idea as a shock absorber.

13:48

Wow.

13:50

The factory showroom

13:51

traces the evolution of Japanese
washing machines over the years.

13:57

Let's start with this one.

13:59

Wow. A real antique.

14:02

It really is!

14:04

Oh wow.

14:06

It's a washing machine from 1951.

14:12

You put in your laundry,
and a liquid detergent.

14:16

Then the central agitator turns
back and forth to wash your clothes.

14:22

OK.

14:23

At the time, it cost 53,000 yen.

14:27

In today's terms, that would
be around a million yen.

14:31

Whoa.

14:33

OK, so you'd have to work several months

14:34

in order to be able to buy
one of these back in 1951.

14:38

Which was when I was born.

14:39

OK.

14:41

Here's the next phase.

14:44

The first washing machine I can remember

14:47

having in our family
was one pretty much like this.

14:51

You can turn this handle to squeeze
the laundry through these rollers.

14:57

Oh, they come out the side?

14:58

Oh OK, so that's actually more
advanced than the one we had.

15:02

Next, a more developed model.

15:05

This is 1970s.

15:07

There's a part for washing,
and a part for spinning.

15:11

Oh, the spin dryers! OK.

15:14

It's a twin-tub washer.

15:16

So you can be washing on this side and
spinning on this side at the same time.

15:21

So if you need to do multiple
washes during the day...

15:25

Now, let's move on to
a later washing machine.

15:30

This one is from the 1980s.

15:33

The two functions have been combined.

15:36

You can wash and spin-dry your
clothes in the same compartment.

15:43

You adjust it using this dial.

15:47

You can select what you're washing.

15:49

Oh, I see. Blouses and sweaters.

15:52

Gloves and socks.

15:54

Wow, it's almost like working
a radio, in fact. Wow.

15:58

So this is the 1980s, and ten years on,
we're getting...ah, this is looking...

16:04

When we get to this stage,

16:05

we start to see digital displays,
with lights for different settings.

16:10

OK.

16:11

At that time, the “fuzzy”
setting was quite popular.

16:16

Yeah. I never understood “fuzzy.”

16:20

It's kind of a “whatever” setting.

16:22

Sensors would identify different
stains and adjust accordingly.

16:26

AI, if you like.

16:29

OK.

16:30

I don't think people were talking about AI
yet in the 1990s perhaps, but OK. Yup.

16:36

Next...this one.

16:39

It's from the 2000s.

16:42

A washing machine,
combined with a dryer that generates heat.

16:48

This was the world's
first top-loading washer-dryer.

16:52

Ah, yeah.

16:53

In the 2000s we finally get to this. OK.

16:58

When you look back,
starting from the 1950s,

17:01

the evolution of these machines
is really quite remarkable, isn’t it?

17:07

And these days,

17:09

most Japanese people do their washing
almost every day, I would say.

17:14

Japan can be hot and humid. Very sweaty.

17:18

Ah, in the summer, yes, definitely.

17:20

Clothing can feel very uncomfortable.

17:23

And it doesn't smell nice.

17:26

So we do a lot of laundry.

17:30

Also, a lot of people suffer
from pollen allergies.

17:36

In the 1950s, huge numbers
of Japanese cedars were planted.

17:41

It's said that in Japan, around 30 million
people are allergic to the pollen.

17:47

It's a serious problem.

17:50

Pollen gets into your clothes and it can
disperse through the rooms of your home.

17:56

So soon after they get home,
many people wash their clothes.

18:01

It's interesting. I mean, there's nobody
in our family has pollen allergies,

18:04

so that's something
I just hadn't thought of.

18:06

Of course, if you have that problem,
and millions of people in Japan do,

18:11

then it's a serious thing
you have to deal with.

18:15

Here's one more factor.

18:18

There's a cultural aspect
to washing in Japan.

18:22

Bad behavior is seen
as something that sticks to you.

18:27

It's like dirt.

18:30

An unclean body is regarded as

18:32

inappropriate if you intend to pray
at a shrine and so on.

18:39

There's a long tradition in Japan
of spiritual and physical cleansing,

18:45

in many forms.

18:48

I think that custom led to the tendency
in Japan to wash clothes frequently.

18:54

Oh, right, OK.

18:58

Plus One

19:03

Hello everyone, and welcome to Plus One.

19:06

I'm Kyle Card.

19:07

When one thinks of washing machines,
clothing often comes to mind.

19:11

But here in Japan,

19:12

they've invented a very special
washing machine that washes...people?!

19:17

Let's go check it out.

19:25

- Hello.
- Hello.

19:26

How do you do?

19:27

I'm great, and yourself? I'm Kyle.

19:30

I've heard that you have
a washing machine for people here.

19:33

- Is that correct?
- Yes.

19:35

Please, take a look.

19:36

All right. Thank you.

19:40

The human washing machine.

19:42

This is the human washing machine?

19:43

Yes.

19:44

Wow. Looks like something out
of a science fiction movie.

19:48

This is actually a mock-up
for display purposes.

19:53

Development is still under way.

19:57

The completed device will be showcased
in 2025 at the World Expo in Osaka.

20:04

I can have a seat? OK.

20:08

It's like a spaceship.

20:09

You get inside,

20:12

shut the door,

20:13

and it fills with fine bubbles.

20:15

- Fine bubbles?
- Yes.

20:17

From head to toe, it cleans you.

20:20

It's entirely automatic.

20:23

Really?

20:24

At the same time,
it assesses your condition using AI.

20:30

It can do all of that by just
sitting in this washing machine?

20:34

Wow.

20:35

And images will be displayed
on the screens around you.

20:40

You don't simply get clean,
it's also mentally refreshing.

20:45

So just by sitting in this machine I can
cleanse my body, heart, and mind?

20:49

Yes.

20:53

The device has many eco-friendly,
high-tech features.

21:00

Think of this as a bath.

21:03

OK.

21:05

It looks like you're blowing in a mist.

21:08

These are actually microbubbles.

21:10

Microbubbles. OK.

21:13

Microbubbles have a diameter
of no more than 0.1 millimeters.

21:20

They can remove dirt
from pores in the skin.

21:25

No soap is required.

21:29

A permanent marker.

21:31

Oh, permanent marker? OK.

21:33

Put out your hand.

21:35

No! Oh!

21:38

Keep your fist closed.

21:40

OK, this worries me.

21:41

Let's begin.

21:45

Kyle's hand is washed with
microbubbles for 20 seconds.

21:51

Without soap, yeah. Wow.

21:55

Done.

21:56

Well, I have to say,
with just a little bit of a water rinse,

21:58

it...the majority has gone away.

22:00

That's very impressive. Wow.

22:05

So I have to ask, why did you decide
to create a washing machine for people?

22:09

Well, in 1970,
a World Expo was held in Osaka.

22:16

And one of the exhibits was
in fact a human washing machine.

22:22

I was in my fourth year
at elementary school.

22:25

I thought, “The future is amazing!
A human washing machine!”

22:32

That thought has stayed with
me ever since. My whole life.

22:37

And now, 55 years later,

22:40

another World Expo
is scheduled to take place in Osaka.

22:45

So I decided to mark the occasion with
a futuristic human washing machine.

22:51

That's the story.

22:52

Ah, that's wonderful to hear.

22:54

Something you experienced
when you were young,

22:56

and you wanted to update it
for the future, right?

22:58

OK

23:01

The psychological aspect of the machine
is being studied at Osaka University.

23:09

Kyle is going to experience it first-hand.

23:15

Just this way.

23:17

All right.

23:21

Is the water warm enough?

23:23

Yeah. Nice temp.

23:28

OK, let's turn it on.

23:30

OK.

23:38

Microbubbles begin filling the tub.

23:42

I've turned into nice white soup here.

23:46

It's hard to believe these are all
microbubbles turning the water white.

23:49

This is amazing.

23:51

It feels a bit tingly too.

23:54

So what is this video I'm watching here?

23:57

In this video,
you're moving through a forest.

24:01

Our software is keeping track of
your autonomic nervous system.

24:06

In the future,

24:08

AI will use that data to select
different visuals, sounds, and vibrations.

24:16

All tailored to the individual user.

24:18

Ah, so it just takes all
of your personal data,

24:21

and it just kind of like creates you
own personalized experience, essentially.

24:25

So where are you getting
all of this data from?

24:28

It's collected through
the seat you're sitting on.

24:32

So what is my data showing right now?

24:35

Your heart rate is currently
about 70 to 80 beats per minute,

24:39

so you're very relaxed.

24:44

The system uses your pulse
to assess stress and fatigue,

24:48

then presents an appropriate video.

And this video here is like
going through a forest.

24:58

I can only imagine, like,
what this going to grow into with AI.

25:02

And just have that personalized
relaxation experience.

25:04

Like, I have so much hope and excitement
for the future of this technology.

25:09

This is just...if this is this relaxing
now, I can't wait for the future.

25:17

Plus One

25:21

As we've seen with these washing machines,

25:24

Japanese products tend to come
with all kinds of different features.

25:27

And I think most Japanese consumers
just take them for granted,

25:31

which consumers in other countries
perhaps wouldn't to a great extent.

25:35

I wonder how much demand there is
for these products outside Japan.

25:40

In China, the Philippines,
the Middle East, and so on,

25:46

models exported from Japan are available.

25:50

But so are other Japanese
models made locally.

25:54

Oh so they're...the models are
different from the domestic ones?

25:58

They're different
from those sold in Japan.

26:01

For example, in India,
they eat a lot of curry.

26:06

Turmeric stains are really
difficult to remove.

26:11

So Indian washing machines
have a function just for that.

26:16

They put these features in just for India?

26:18

They do.

26:20

Whoa.

26:21

Also, in the Middle East, many women
wear a garment called an abaya.

26:29

It's made from very thin fabric, and often
features a stylish, decorative hem.

26:36

In a washing machine,
abayas are very easily damaged.

26:42

So there's a special mode
that emulates a gentle handwash.

26:48

Wow. I had no idea that

26:50

they're thinking up all
these features for different countries.

26:53

Interesting.

26:55

Looking at all these models
through the years,

26:58

every time a new one comes out,

27:00

it's kind of state-of-the-art
for its time.

27:04

Today, we've seen washing machines
with all sorts of different features.

27:10

They can make clothing
water repellent again.

27:14

Stylish garments that you'd previously
take to the dry cleaner's

27:19

can now be washed at home.

27:22

That's true, yes.

27:24

One characteristic of Japanese
washing machines is attention to detail.

27:30

I think the devices produced here can
compete with anything made anywhere else.

27:38

I'm sure that, eventually,

27:41

we'll reach the point where
the laundry comes out folded!

27:46

Well I'm sure if it did that there would
be plenty of people that would welcome it.

27:49

Thank you very much.

27:51

It was my pleasure.
