FRONTRUNNERS

00:08

Japanese food can be limiting for visitors,

00:10

as there are so few vegan-friendly places.

00:14

Delicious. This vegan food is very nice.

00:18

- How did he capture the flavor so well?
- It is very authentic.

00:22

Wow!

00:23

The aim is to inspire diners to try, and to make sure they enjoy it.

00:30

Vegan washoku chef
Kusumoto Katsumi

00:37

Tokyo's upmarket Jiyugaoka district.

00:40

This ivy strewn building is home to

00:42

one of the world's top-rated vegan restaurants.

00:48

- One "eel," one mushroom, one miso ramen.
- Got it.

00:54

Chef Kusumoto Katsumi's unique approach to traditional Japanese cuisine

00:59

adapts orthodox dishes to suit the needs of diverse diners.

01:07

What did these customers order?

01:11

An all plant-based fried "pork" cutlet.

01:18

Meat-free yakitori "chicken" skewers.

01:27

And plant-based ramen.

01:33

All much-loved Japanese favorites,

01:36

recreated entirely without the use of animal products.

01:47

And it's not just the presentation.

01:49

Everything from flavor to texture to aroma is just like the originals.

01:57

In 2020, this restaurant reached the top spot on a popular online guide

02:02

with user ratings for over 100 thousand vegan restaurants worldwide.

02:09

- Which order's this?
- "Eel."

02:14

Globally, vegetarians, vegans,

02:16

and those with religious dietary restrictions

02:19

make up around one third of the entire human population.

02:26

And with vegan, halal, and other options

02:29

still limited in Japan compared with many other countries,

02:32

international tourists make up a large portion of Kusumoto's diners.

02:39

One of his most popular dishes is this plant-based recreation of "unaju."

02:50

Traditionally, this dish is made with eel.

02:56

Grilled in a rich "tare" sauce and served over rice,

03:00

it's an enduringly popular Japanese favorite.

03:06

Kusumoto's vegan version subs in tubers like burdock,

03:10

"nagaimo" yams, and lotus root.

03:16

I can't let you film the ratios.

03:21

- Are they secret?
- They are.

03:25

The resulting blend is spread onto sheets of dried nori seaweed.

03:32

And scored to approximate the appearance of the real thing.

03:42

So, now I'm going to grill these. But I can't let you film that either.

03:49

- Should we stop filming?
- Yes, please.

03:55

Kusumoto's techniques are full of closely guarded secrets.

04:04

Finally, a bed of combined brown and sticky rice...

04:10

is topped with the faux eel fillets grilled in a smoky aromatic marinade.

04:17

It's a plant-based unaju worthy of world number one status.

04:24

So what do the diners think?

04:33

After the initial surprise, how does the flavor stack up?

04:41

Delicious. This is the first time I came. This vegan food is very nice.

04:48

Everything, finished.

04:52

For a non-vegan... I could eat this. It's like I'm eating normal food.

05:00

They've been in Japan for ten days, and say this is their best meal so far.

05:07

Thank you!

05:08

Kusumoto's ultimate aim is to create dishes

05:11

tasty enough to satisfy vegans and non-vegans alike.

05:18

Say you have a couple where she's vegan and he's an omnivore,

05:24

and they come to us on a date to celebrate her birthday.

05:31

If we can't serve a meal that he can enjoy too,

05:36

then that can potentially wind up spoiling the occasion for both of them.

05:44

We ought to provide meals that can satisfy omnivores too.

05:48

So that's my goal as a chef.

05:54

Everyday Japanese dishes like ramen,

05:57

"karaage," yakitori, "okonomiyaki,"

06:02

I strongly believe that, moving forward,

06:05

it will be very important

06:07

to adapt those items to suit the needs of vegans, too.

06:15

A key focus for Kusumoto is the dashi stock

06:18

that forms the basis for most Japanese dishes.

06:22

For his vegan menu, he uses a mushroom base,

06:25

dried and then rehydrated to intensify the flavor.

06:33

I air them until they're bone dry.

06:36

How long depends on the weather, and the season.

06:40

So not just a day, then?

06:42

Days upon days.

06:47

Conventionally, Japanese stock is made from

06:50

dried, smoked skipjack tuna shavings, or "katsuobushi."

06:57

But Kusumoto blends various kinds of mushrooms

07:01

to recreate the flavor of fish and animal-based stocks.

07:12

These are just rehydrated mushrooms,

07:15

but how you heat them alters the flavor.

07:18

It's all based on careful research and comparison.

07:23

The possibilities for these stock blends are endless,

07:27

with even factors like region of origin and water quantity coming into play.

07:33

For Kusumoto, it's an ongoing process, further refined on a daily basis.

07:40

Each stock has a different color.

07:45

And of course, different flavors and aromas, too.

07:50

I keep careful track of data on which ones taste stronger,

07:54

or sweeter, and so on.

07:59

And these mushroom stocks are a big part of what sets Kusumoto apart.

08:10

Here's your order.

08:13

With a baby on the way, this Japan-based Swiss-American vegan couple

08:18

have finally managed to get a reservation

08:20

for their first visit to Kusumoto's restaurant in two years.

08:28

After enjoying their starter...

08:32

The next course is plant-based yakitori skewers.

08:36

- Here's your vegan yakitori.
- Great!

08:42

The texture is so realistic, it's hard to believe it isn't chicken.

08:47

And there's an extra surprise in store.

08:51

You can eat the "charcoal" too. Yes, it's a new addition.

08:58

- All made from vegetables.
- What kind of vegetables?

09:02

Try it and see!

09:07

Details like this fried yam "charcoal"

09:11

all add to the enjoyable dining experience.

09:16

Aren't customers surprised?

09:17

At first, but that soon turns to delight.

09:22

People enjoy those little gimmicks.

09:28

After the yakitori comes the much-anticipated vegan eel unaju.

09:42

Yeah! This pose, yeah.

09:46

This is from two years ago.

09:50

Taken here?

09:51

That's right. We were here two years ago.

09:56

This "eel" is what brought us back here today.

10:00

I couldn't wait to try it again.

10:07

And is the taste as good as they remembered?

10:14

Have you tried real eel?

10:17

I have. Before I went vegan.

10:21

The real thing is good, too, but this holds its own.

10:26

Don't know what it's made from, but it's great.

10:31

The meal is rounded off with a raspberry-flavored soymilk mousse.

10:40

I don't use any egg white or dairy.

10:43

And Kusumoto's sense of fun is once again on display

10:47

with a "tree" made from vegan green tea sponge cake.

10:51

Here's your raspberry mousse.

11:04

A fitting end to this multi-course vegan dinner.

11:14

And Kusumoto makes sure to personally see off these two satisfied customers.

11:22

Good night.

11:40

On his day off, we join Kusumoto on a trip to Nagano Prefecture,

11:44

to visit mushroom grower, Kaneko Keisuke.

11:49

(Iiyama, Nagano Pref.)

11:54

Together, they head deep into the local mountains.

12:12

Wow.

12:15

Kaneko's enoki mushrooms are grown using locally felled sugi cedar.

12:26

Most commercially available enoki are cultured on a substrate

12:30

made from dried, ground corn cobs, imported from overseas.

12:39

But Kaneko employs a more traditional approach,

12:42

using domestic cedar chippings,

12:44

for an altogether more flavorful, aromatic end product.

12:57

Kaneko-san's enoki are totally different,

13:00

even down to the stock they produce.

13:04

I use them because they taste so good.

13:07

- There's a big mushroom over here.
- Wow.

13:12

This passion for mushroom growing makes Kaneko a key partner for Kusumoto.

13:23

And that same dedication is currently aiding

13:26

the development of another new product.

13:32

Kusumoto is in Hiroshima for a meeting with a major food manufacturer.

13:40

Together they're working on a vegan-friendly "tonkotsu" soup.

13:47

Tonkotsu is a cloudy broth,

13:49

typically made by boiling pork and chicken bones.

13:55

And tonkotsu ramen has recently been enjoying a global boom in popularity.

14:02

In January 2023,

14:04

Kusumoto even opened a tonkotsu ramen pop-up restaurant in Los Angeles.

14:12

The 1,000 advance reservation tickets quickly sold out,

14:17

with a further 2,000 hopefuls

14:19

adding their names to the cancellation waiting list.

14:23

And the success of this venture

14:25

was a sign of Kusumoto's growing reputation overseas.

14:32

Like the dishes in his restaurant,

14:34

his plant-based take on tonkotsu ramen also relies on mushrooms.

14:41

Give it a try.

14:51

- How is it?
- It's tonkotsu!

14:55

- That unmistakable richness.
- It's just like the real thing.

14:59

It captures the pork fat perfectly, even though I know it's plant-based.

15:07

There must be some animal in here!

15:11

Passing for tonkotsu with Japanese diners

15:13

means it'll definitely convince foreigners.

15:16

What's Kusumoto like as a person?

15:19

What's he like?

15:21

Kind of a rulebreaker, in a good way.

15:26

He never concerns himself with any sort of obstacles.

15:30

And he's always on the hunt for the next exciting challenge.

15:43

Straight out of high school,

15:44

Kusumoto Katsumi went into the world of French cuisine.

15:49

Then, in his early 30s,

15:51

he was made head chef of an exclusive, members-only Japanese restaurant.

15:57

And there too, his novel, refreshing approach brought considerable success.

16:06

But after years of steady progress,

16:09

he reached a turning point in his career as a chef.

16:16

One customer told me they wanted to bring along some Muslim guests.

16:23

And they told me they couldn't eat pork or drink alcohol,

16:27

and that even dishes that used cooking alcohol were out.

16:32

Back then, I had no idea about dietary restrictions like that,

16:37

so I decided to learn more.

16:41

He poured all of his expertise into creating

16:44

a halal-friendly Japanese course menu for his scheduled visitors.

16:50

However...

16:55

I messed up.

16:56

They left most of the dishes I prepared, weren't into them at all.

17:02

They'd take one mouthful and leave the rest.

17:05

As a chef, that must have been a shock.

17:08

A major shock.

17:09

It felt like as soon as I couldn't use fish, or meat, or alcohol,

17:13

my dishes weren't even worth finishing.

17:17

It was very upsetting.

17:24

And it was after that,

17:25

that Kusumoto shifted his focus to plant-based "washoku."

17:31

Sinking himself into day after day of painstaking trial and error.

17:39

Finally, one day, someone said how tasty my dishes were,

17:44

and after the meal,

17:45

the plates came back with not a scrap of food left on them.

17:50

And the joy of that moment truly motivated me.

17:54

It's what's kept me going as a chef ever since.

18:00

(Himeji, Hyogo Pref.)

18:05

- Hello.
- Hi there.

18:12

Here, Kusumoto is engaged in yet another initiative.

18:20

Once a month, he comes to help out with the meals at this nursery.

18:25

It's attended by 240 children aged zero to five.

18:37

The challenge here, is food allergies.

18:43

- Many allergies this year?
- Some kids with egg or nut allergies.

18:48

- No milk allergies?
- Not this year.

18:51

- And how many egg allergies?
- Three children.

18:55

In fact, the last few decades have seen an increase in infant food allergies,

19:00

creating headaches for nurseries like this one.

19:05

For kids with allergies,

19:06

we use different colored utensils and separate trays,

19:10

and seat them separately.

19:12

For some, just one nibble from the classmate next to them

19:15

and they could go into anaphylaxis and even die.

19:19

That makes mealtimes stressful for staff

19:22

but the kids don't understand the dangers,

19:24

so being isolated can make them feel lonely.

19:31

But the risks posed by serious allergies

19:34

are so great that there is usually no option

19:36

but to isolate these children with their own dedicated menu.

19:43

In response, with the aim of giving all children the chance

19:47

to enjoy a shared menu together,

19:50

principal Uetsuki Kaoru reached out to Kusumoto.

19:55

I don't think there's anything wrong with their existing approach.

20:00

The key thing is to prevent catastrophe.

20:03

But of course,

20:04

I'm a pro when it comes to making tasty meals for my restaurant

20:08

without the use of certain ingredients.

20:11

That's my area of expertise.

20:15

That knowhow can help in the struggle against allergies.

20:18

And also make lunch even more delicious.

20:23

According to research, around 70% of food allergies in Japan

20:28

can be accommodated simply by switching to a vegan menu.

20:36

Today's main dish is okonomiyaki savory pancakes

20:40

without the traditional egg to bind them.

20:45

And in place of meat,

20:46

Kusumoto uses enoki mushrooms from his trusted supplier in Nagano.

20:53

Together, under Kusumoto's guidance,

20:55

the kitchen staff efficiently prepare vegan okonomiyaki for all 240 children.

21:08

Even the sauce is plant-based.

21:12

As is the egg-free mayonnaise.

21:22

Yum, very good.

21:26

On today's special menu,

21:28

everything from the okonomiyaki to the soup and dessert

21:32

is entirely free of animal products.

21:36

Something smells good!

21:38

And today, all the children,

21:41

both those with allergies and those without,

21:43

can sit together and enjoy their lunch around the same table.

21:48

Another challenge is providing food the kids will enjoy.

21:52

Even for dishes that adults might love,

21:55

children don't always respond the same way.

21:58

They'll say "yuck!" right to your face, even to a world-leading chef.

22:07

But in Japan, as elsewhere, not all children are fond of vegetables.

22:12

How will they respond today?

22:15

Let's eat!

22:30

Yum!

22:36

Yummy!

22:39

How is it?

22:41

- Really good.
- Thank you!

22:44

- This has meat in it.
- Definitely.

22:51

Tastes like meat, but it's mushroom!

22:59

Good news everyone! We have seconds!

23:04

The plant-based okonomiyaki have turned out to be a major hit.

23:13

They're loving it.

23:20

In Japan there's a saying about "eating from the same pot."

23:25

But in my opinion, there's still some work to do

23:28

before everyone can enjoy the same food around the same table.

23:33

And I want to work towards achieving that.

23:37

That's my goal.

23:40

As part of his work to promote these ideals,

23:43

Kusumoto visits Fukushima Prefecture.

23:52

- Isn't it T-shirt weather today?
- It is a bit chilly.

23:59

I chose the wrong outfit.

24:03

He's here to showcase vegan washoku

24:06

to the chefs of the future at this culinary college.

24:10

Despite the growing momentum for veganism worldwide,

24:13

awareness in Japan remains comparatively low.

24:17

But Kusumoto hopes to convey the potential of this new dietary lifestyle.

24:23

Put the scallions on top, like so.

24:28

And the best way to help students relate

24:30

is by letting them taste the dishes for themselves,

24:34

starting with Kusumoto's famous tonkotsu ramen.

24:43

Yum!

24:46

Have you finished already?

24:49

It's really good! So good you can't tell the difference.

24:54

The UK has a lot of vegetarians and vegans.

24:58

So this is a tonkotsu-style ramen that even they can enjoy.

25:03

And I have no time for purist takes like "this isn't real tonkotsu."

25:07

Because making meat-inspired dishes that everyone can enjoy

25:11

is a really valuable market.

25:18

And some students are so inspired

25:21

that they corner him after the session.

25:26

So I tried the soup, and I felt like it had this bamboo-like acidity.

25:33

Did you use bamboo shoots in it?

25:36

That's a great question.

25:38

I use the broth from boiling bamboo shoots,

25:42

and it helps to add to the ramen-like flavor.

25:46

So there were no actual bamboo shoots in the soup,

25:50

but I did use a bamboo-infused broth.

25:55

Overturning convention is key.

25:59

What were those pork-like notes?

26:01

I thought that might be garlic and shiitake...

26:06

Is that a trade secret?

26:08

It sure is.

26:10

Makes sense.

26:14

A student like this will go far.

26:18

Thank you so much. I really enjoyed today.

26:27

It's all about sowing the seeds.

26:31

If these young people take an interest in veganism,

26:35

with the technical grounding available in Japan,

26:38

I think they can definitely put themselves up there

26:41

among the world's top chefs.

26:45

I want to keep sowing those seeds

26:48

and I do feel a big responsibility

26:50

to try and keep on inspiring the next generation.

26:54

Today really reinforced that.

26:59

Kusumoto Katsumi's mission to bring Japanese washoku

27:02

up to speed with the global vegan movement continues.

27:07

And that journey is also helping to expand

27:09

the potential of Japan's age-old culinary traditions.

27:15

So, what is it that motivates him as a "frontrunner" in his field?

27:23

My diners are from different cultures

27:26

and have a variety of dietary restrictions.

27:29

I spend time thinking and innovating.

27:32

And I prepare new dishes

27:33

that I hope will satisfy and delight all of these individuals.

27:38

The moments when they tell me they enjoyed the meal,

27:40

that this is the flavor that they were looking for,

27:43

are unforgettable for me as a chef.

27:46

When they say "that was delicious"

27:49

or "I didn't know Japanese food could be this good,"

27:52

that's a great feeling.

27:55

And that's what motivates me.
