Beautifully packed in various containers...

00:08

These bento abundantly incorporate local ingredients and are a delight for the palate as well as the eyes...

00:18

Yes, it's the uniquely Japanese culinary culture of ekiben.

00:26

Ekiben are typically purchased at train stations and enjoyed during train journeys.

00:32

Join us on a Japan's culinary journey exploring ekiben.

00:40

EKIBEN JAPAN!

00:45

Today, we're taking a look at a comfort food from the northern seas.

00:55

On the large island of Hokkaido, located in the northern part of Japan, the Muroran Line runs along the southwestern coastline.

01:12

The cozy Bokoi Station, nestled in the city of Muroran, is where the ekiben called Bokoi-Meshi is sold.

01:24

Made by three family members, they're limited to just 40 per day.

01:29

Because of their limited availability, they're known as a rare ekiben.

01:41

These customers traveled 800km for this ekiben.

01:47

My wife learned about the surf clam bento
sold here from television.

01:52

She was eager to try it
but never had the opportunity.

01:58

We're excited to try it now.

02:01

We'll enjoy it together.

02:09

Let's take a look at what's inside this rare ekiben.

02:14

The first thing that you'll notice when you open the box is a large clam of about 10cm in length.

02:24

Inside the shell is a beautifully arranged onigiri with ample clam meat.

02:36

As you take a bite...

02:38

the clam's sweetness fills your mouth.

02:47

With its soft texture and delicate flavor, it transports you to the sea.

02:57

This surf clam is called hokkigai.

03:08

The place name Bokoi is said to originate from a phrase meaning "a place with many hokkigai"

03:15

in the language of the Ainu, the indigenous people.

03:24

It's said that nearly 90% of hokkigai in Japan comes from Hokkaido.

03:38

Harvesting them is not an easy task.

03:48

The cold is tough in winter.

03:52

There's also waves, and wind too.

03:55

Sometimes there's snow, like today.
The weather is a factor.

03:59

I think it's -1℃ or -2℃ today,

04:04

but we still work even in -15℃.

04:08

In that temperature,

04:11

my legs sometimes hurt so much
that I want to cry, but I manage.

04:19

I really like hokkigai.

04:24

I could eat it every day.

04:27

When I'm at an izakaya with friends,
I'll order hokkigai, and they'll scold me.

04:36

"You harvest those yourself!"
That's how much l love them.

04:40

I'm lucky that I'm able to harvest
something that I'm fond of.

04:48

At a seafood market near the port, freshly caught hokkigai are put out for sale.

04:59

It's a long-living clam.

05:00

I don't know of any other clam
that takes this long to grow big.

05:08

These are about seven to eight years old.
These small ones.

05:14

These big ones are probably
about 35 years old.

05:19

35 years! Who knew clams could live that long!

05:26

Hokkigai are probably the most
versatile clams for cooking.

05:31

They're good in salads,
butter-grilled, fried...

05:35

My favorite is frying them.

05:37

I would say they can be
used in almost anything.

05:44

Hokkigai is something of a comfort food in this area.

05:51

Our restaurant has over 25 hokkigai
dishes on the menu now,

05:57

so you can probably experience
most hokkigai dishes in Japan.

06:06

Raw hokkigai sliced with skillful knifework...

06:11

is topped on rice to make a hokkigai rice bowl.

06:23

For those who prefer it cooked...

06:25

there's butter-grilled hokkigai, a dish with a fragrant aroma.

06:38

Hokkigai coated in batter and deep fried is a favorite of Yamamoto from the market.

06:48

And there's the restaurant's most popular dish.

06:52

Curry rice with briefly cooked hokkigai.

07:05

Three freshly-caught hokkigai are
used for our curry.

07:10

The sweetness from the hokkigai blends
really well with the curry. It's very delicious.

07:28

Let's gaze out towards Hokkaido's sea...

07:31

as we return to enjoying our ekiben.

07:39

These ekiben are made by three family members.

07:49

Equally as important as the hokkigai is the seasoned rice used for the onigiri.

08:07

The unsung hero that supports its flavor is kombu.

08:17

This kombu is called yayan kombu.

08:20

It's a kombu species only found in Muroran.

08:24

It's a valuable kombu species
as a specialty of Muroran.

08:31

Kombu, or kelp, is a type of seaweed essential for Japanese cuisine.

08:39

Yayan kombu, used in Bokoi-Meshi, thrive near the steep cliffs at Muroran's sea.

08:49

They're roughed up,
being battered by the waves.

08:55

"Yayan" means useless or just normal.

09:02

With that sort of name, this kombu species
has been overlooked for a long time.

09:09

Not many fishermen bother to collect yayan kombu since they look unattractive and are unprofitable.

09:19

However, having fallen in love with its flavor, Sekine Katsuji commissions fishermen to harvest yayan kombu for him.

09:31

I'm thankful.

09:33

Without this kombu, there would be no Bokoi-Meshi.

09:40

It's precious.

09:47

The important role of yayan kombu is in making dashi, or broth.

09:56

With a soup infused with the strong umami of kombu, rice is cooked like paella.

10:07

The dashi is made by Issei, Katsuji's son.

10:13

I'm careful not to let it boil
so the kombu's umami is preserved.

10:20

At 80℃ the thickening components
start to break down.

10:28

The kombu is simmered, with close attention paid to the heat.

10:36

It's not just dashi from kombu.

10:39

There's also dried, smoked mackerel, and shiitake mushrooms.

10:44

Dashi is made from each of these ingredients,

10:55

and the three dashi are then combined.

10:59

This is crucial.

11:05

We make the dashi separately.

11:07

If you combine them when the ingredients
are still inside, the flavors will be absorbed.

11:14

The kombu absorbs the fish flavor
and the fish absorbs the kombu flavor.

11:21

It tastes good even without salt
because the umami stimulates your taste buds.

11:29

Even without salt,

11:33

it's delicious.

11:37

The carefully prepared dashi gives the onigiri a rich taste.

11:57

Together with the main ingredient, hokkigai, and the supporting yayan kombu,

12:02

there's one more ingredient in Bokoi-Meshi that ties the flavors together.

12:13

On this sunny day, Katsuji sets out for that ingredient.

12:22

He's heading out to sea together with Issei to collect seawater.

12:36

I realized that salt is the essence of flavor,
so I searched for the best salt.

12:41

But I couldn't find the right one.

12:47

Since Muroran is surrounded by the ocean,
I realized I had to make salt with seawater for the bento.

13:01

Using a pump, he fills ten 20-liter containers with seawater.

13:29

The seawater is boiled for an entire day.

13:41

It's then left to dry for another day to produce salt.

13:50

It's literally the salt of Muroran.

13:52

It comes back to the idea of offering
local produce to those who visit.

14:04

I don't think there's anybody
who makes salt just for bento.

14:11

That's unheard of, indeed.

14:20

The best thing is when people
express their appreciation.

14:24

We decided to be fully dedicated,
and this is how it's turned out,

14:29

so it's wonderful when our customers say
they enjoyed the bento.

14:42

Savoring the deep sentiments of this heartfelt bento, let's carry on with our journey.
