In Part 1, we explored the signature menu and limited-edition ramen at Ramen Daikinboshi. In Part 2, we dig into the life of Yamamoto himself — from studying mechanical engineering to working at an Italian restaurant and then a factory, before finding his way to ramen. Diagnosed with an incurable disease at 23, and facing a property deal collapse during COVID, this is the story of a man who always knew he'd open a shop in Chichibu.

01 From engineering to Italian food to ramen

AsamiAsami

We've been hearing a lot about your training and your approach to ramen. Now I'd like to ask about your life story up to this point -- the path that brought you here.

YamamotoYamamoto

Sure.

AsamiAsami

You're originally from the former Otaki Village in Chichibu. Did you go to high school around here?

YamamotoYamamoto

I went to Chichibu Noko (Chichibu Agriculture & Engineering High School).

AsamiAsami

Oh, Chichibu Noko. That's the school with all the specialized departments -- food science, forestry, and so on, right?

YamamotoYamamoto

That's right. Though I was in the mechanical engineering department.

AsamiAsami

Mechanical engineering! (laughs)

YamamotoYamamoto

After graduating from mechanical engineering, I went to culinary school.

AsamiAsami

Wow. Why that path? Mechanical engineering to culinary school -- how did that happen?

YamamotoYamamoto

I just really loved eating.

AsamiAsami

Were you on the heavier side?

YamamotoYamamoto

Yeah, I was (laughs).

AsamiAsami

I love the reasoning (laughs).

YamamotoYamamoto

When I was entering high school, I actually considered the food science department, but I ended up going with the easier one to get into. Still, I thought, I should pursue what I really want to do. So I went to culinary school, got my cooking license in a year, and my first job was at an Italian restaurant.

AsamiAsami

Which restaurant was it?

YamamotoYamamoto

A place called Mizzet in Urawa.

AsamiAsami

Huh. But you left after six months, right?

YamamotoYamamoto

I did.

AsamiAsami

First of all, why Italian?

YamamotoYamamoto

Because I loved pasta.

AsamiAsami

Your reasons are wonderfully simple (laughs). You love eating, you love pasta, and you just built a career on that.

YamamotoYamamoto

I think doing what you love is a good thing.

AsamiAsami

So how was the Italian restaurant?

YamamotoYamamoto

I lost about 20 kilograms in six months.

AsamiAsami

That's intense.

YamamotoYamamoto

It was rough. Monday was our day off, but if there was a holiday, we'd end up working two straight weeks without a break. I'd be at the restaurant from 6 or 7 in the morning until late at night.

AsamiAsami

No wonder you lost weight... Did you decide to quit because it was just too much?

YamamotoYamamoto

That was part of it. But there was also a senior coworker, one year older than me, who told me, "Yamamoto, you should really quit." That had a big impact.

AsamiAsami

Was that senior also working through the same grueling schedule?

YamamotoYamamoto

Yeah. He was there every single day. But one day out of the blue he said, "I'm quitting first, but Yamamoto, you should quit too." So I went back to Chichibu.

AsamiAsami

After coming back to Chichibu, what did you do?

YamamotoYamamoto

I got a factory job.

AsamiAsami

So that's where the mechanical engineering background came in handy. What a plot twist.

YamamotoYamamoto

Right. It was a factory that made molds for car parts.

AsamiAsami

I see. How long were you there?

YamamotoYamamoto

From about age 20 to 25. But during that time, I started thinking, I don't want to spend my life in a factory.

YamamotoYamamoto

I had my cooking license, and I figured I could make a go of it in the food business in Chichibu. But after the tough experience at the Italian restaurant, I'd become a bit turned off by the food industry altogether.

AsamiAsami

I can understand that. If you lose 20 kilos from overwork, anyone would feel that way.

YamamotoYamamoto

At that point, I was even thinking, I'm done with pasta too (laughs).

AsamiAsami

And from there you went to ramen. Why ramen?

YamamotoYamamoto

Because I thought it would be the most practical thing to do in Chichibu. I didn't have my heart set on any one type of food. I even considered offal cuisine. But when I weighed all the options, ramen seemed like the best fit for me.

AsamiAsami

So even at that point, you already had a sense that you wanted to make a living in food, in Chichibu.

YamamotoYamamoto

Absolutely. Even when I left for training, I always planned to come back and do it in Chichibu. That was there from the very beginning.

02 What training taught him — and what it exposed

AsamiAsami

Where did you do your first ramen training?

YamamotoYamamoto

At Joshouken in Honjo. At the time, the guy who now runs Golden Tiger was the manager there.

AsamiAsami

Ah, Golden Tiger in Kumagaya. The famous shop known for their TKM, right?

YamamotoYamamoto

That's right. I'd been going there as a customer before I even decided to become a ramen chef. The owner was really easy to talk to, and I loved the tsukemen there. So I asked to join, and once I started, I realized that ramen was the right career for me. It didn't feel like a burden.

AsamiAsami

What did you find interesting about it?

YamamotoYamamoto

Making soup. The flavor completely changes depending on how you make the soup. That's what fascinated me.

YamamotoYamamoto

Also, Kanazawa-san (the manager at the time, now owner of Golden Tiger) really set me straight. I was there for two and a half years, and I think he fixed a lot of what was rotten in me.

AsamiAsami

"Rotten"?

YamamotoYamamoto

Less aggressive, more like... I was always making excuses.

YamamotoYamamoto

I got scolded a lot. He'd pull me aside and chew me out every time. "Stop making excuses." Whenever a senior told me something, I'd immediately say "but" or "why" -- I couldn't help it. But I needed someone to tell me. I wouldn't have realized it on my own.

AsamiAsami

Do you feel like you were able to overcome that?

YamamotoYamamoto

I do. When he stopped saying it, I thought to myself, "Huh, maybe I've changed."

AsamiAsami

What happened after that?

YamamotoYamamoto

After Joshouken, I went to an affiliate shop in Gunma. They asked me to try running a small shop on my own.

YamamotoYamamoto

It was a tiny place, about 6 to 8 counter seats, and I ran it almost by myself. It was good experience, but I got stressed out again. The reason was the fear of not hitting sales targets.

AsamiAsami

But you were an employee, right? Even as an employee, you were that invested in the numbers?

YamamotoYamamoto

I was. I knew I wanted to open my own place someday, so I was always crunching the numbers. I was in Isesaki, making about 30,000 yen a day in sales. I kept thinking, "If this is what it's like in Isesaki, what would it be like back in Chichibu?"

03 Diagnosed at 23. He still chose Chichibu

YamamotoYamamoto

Actually, I was diagnosed with an incurable disease at 23. It's called ulcerative colitis.

AsamiAsami

A disease where ulcers form in the colon, right?

YamamotoYamamoto

That's right. The doctor at the hospital in Chichibu told me, "This doesn't go away." With medication, you can often live normally, but the symptoms come and go unpredictably. I believe it flares up when I'm under heavy stress.

AsamiAsami

What kind of symptoms?

YamamotoYamamoto

Bloody stool and intense abdominal pain. It feels like someone is squeezing your organs. In severe cases, people need a colostomy bag, but I haven't gotten to that point.

YamamotoYamamoto

Lately, it hasn't completely disappeared, but the symptoms are mostly gone. Now I just try to keep things as stress-free as possible.

AsamiAsami

That must have been really tough.

YamamotoYamamoto

When I left the shop in Isesaki, the symptoms flared up again. I needed to see specialists at a university hospital in the Tokorozawa area, so I looked for my next job somewhere closer. That's when I started working at Yoshikawa in Kawagoe.

AsamiAsami

How were those two years of training?

YamamotoYamamoto

It was probably the most intense period of all. If I hadn't met Kanazawa-san, I wouldn't have a ramen career at all. But after him, the next biggest influence was Yoshikawa.

YamamotoYamamoto

Up until then, I'd mostly been making tsukemen and rich, heavy soup ramen. But Yoshikawa was all about clear chicken chintan broth and fish-focused ramen -- completely different from anything I'd done before.

I got to fillet a lot of fish there too. They had a seafood rice bowl on the menu, so the first thing I'd do every morning was break down a whole fish. A ramen shop where you start the day filleting fish -- that was something else.

AsamiAsami

So would you say the limited-edition style came from Joshouken, and the regular menu foundation came from Yoshikawa?

YamamotoYamamoto

Exactly. The limited-edition specials lean more toward the Joshouken style, and the regular menu is built on the Yoshikawa foundation.

AsamiAsami

And from there, you finally made your way back to Chichibu.

YamamotoYamamoto

Even back in high school, my part-time job was at a ramen shop, so in the end, it's always been ramen for me.

AsamiAsami

What made you finally come back?

YamamotoYamamoto

I heard that the ramen shop where I worked part-time in high school was closing, and they asked if I wanted to take it over. So I called my boss and said, "I'm sorry, but I have a chance to open a shop in Chichibu. I need to leave."

04 The property fell through, then COVID hit — he opened anyway

YamamotoYamamoto

But that deal fell through. The old couple living upstairs didn't want the noise. They said "We don't want it to be noisy," and the property was off the table.

AsamiAsami

Oh no... So you quit your job and came back, only to find out the whole thing had fallen apart.

YamamotoYamamoto

That's right. And then, two or three months later, COVID hit.

YamamotoYamamoto

I came back around the end of 2019, planning to start looking for a property in the new year. But then the pandemic happened. I started wondering, "Can I really do this?"

But during that time, I went to the Chamber of Commerce, talked to mentors, and prepared my financing. I was searching for properties the whole time.

YamamotoYamamoto

I wasn't dead set on this exact location from the start. I was looking at other places too, but nothing came up. Eventually, this was the one.

AsamiAsami

This place used to be a hair salon, right?

YamamotoYamamoto

That's right. The counter you see now didn't exist at first -- it was nothing but empty walls. So the initial investment was significant, and I had my doubts.

But because it was during COVID, I had time to think. In the end, I made my peace with it and decided, "I'm doing it here."

AsamiAsami

By the way, the name "Daikinboshi" has an interesting origin too, doesn't it?

YamamotoYamamoto

The "Dai" comes from Taishouken. The "Kin" comes from Golden Tiger -- the "gold."

But "Daikin" alone sounded weird (laughs). Plus, every shop I trained at was an incredible place, and I wanted to beat them. In sumo, "daikinboshi" means pulling off a major upset -- a lower-ranked wrestler defeating a yokozuna. That's why I named it Daikinboshi.

The incurable disease, the training, the detours — everything led to this shop.

05 What's next for Daikinboshi

AsamiAsami

You've trained at multiple shops, dealt with an incurable disease, and kept pushing through. All of that experience and wisdom has come together in Daikinboshi as it stands today.

YamamotoYamamoto

That's right. I'm truly glad I was able to open this place.

AsamiAsami

To wrap up, what do you want to do going forward with Ramen Daikinboshi, or in your life in general?

YamamotoYamamoto

First, I want to hire employees and expand to more locations. Not a huge number -- but I'd like one or two more shops.

Right now, I'm kind of maxed out on my own. Both in terms of growing the business and learning to manage people, I want to take things to the next level.

AsamiAsami

What kind of person are you looking for?

YamamotoYamamoto

Someone I'd want to work with. But the one thing I've been told from the very beginning is that an honest, sincere person is best.

I wasn't always like that myself, so I feel it even more strongly. For better or worse, someone who can just say "yes" and "I understand." Right now, I think sincerity is the most important quality.

AsamiAsami

Do they need cooking experience?

YamamotoYamamoto

Not at all.

AsamiAsami

There you have it. Sincere people, please apply (laughs).

YamamotoYamamoto

Please do (laughs).

AsamiAsami

A second location, a third -- I'm looking forward to it.

YamamotoYamamoto

Personally, I'd love to open a tsukemen specialty shop.

AsamiAsami

Oh, a tsukemen specialty shop. Going all in.

YamamotoYamamoto

Who knows, I might call it "brothless tsukemen" and actually serve pasta (laughs). Vongole tsukemen, anyone?

AsamiAsami

By the way, do you still like pasta?

YamamotoYamamoto

I do.

AsamiAsami

Still a pasta lover after all (laughs).

AsamiAsami

But really, life throws a lot at you. I think experiencing the bad times is important too.

Someone who used to make excuses for everything has come this far, and now says, "What I need most is an honest person." I think that says something really significant.

YamamotoYamamoto

It really does.

AsamiAsami

The ramen's delicious, your story is fascinating, and you mentioned you want to strengthen the branding -- so I'd love for us to keep working together through Asami Seisakusho as well.

YamamotoYamamoto

Absolutely. Thank you so much.

AsamiAsami

That was Yamamoto-san from Ramen Daikinboshi. Thank you for your time today.

YamamotoYamamoto

Thank you very much.
