Reading time: about 6 minutes
Hi, I'm Hiroshi from "Ramen, Beer, and Sometimes Blogging."
I went back again to Mouko Tanmen Nakamoto in Hashimoto. And of course I ordered the same thing: Hokkyoku Ramen with stir-fried vegetables, spice level 10x. Two visits ago it was this same bowl, last time it was the standard Hokkyoku Ramen at 10x, and now here I am again.
At this point, I think I'm addicted.
This post is for you if:
- You want the hours and access details for the Hashimoto branch
- You can't decide between the standard Hokkyoku and the stir-fried veggie version
- You're wondering just how hot "10x" really is
The short answers
- The Hashimoto branch is about a 10-minute walk from Hashimoto Station (JR Yokohama Line / Keio Sagamihara Line). Hours are 11:00–15:00 and 17:00–21:00, closed Mondays (open if Monday is a public holiday, closed the following Tuesday instead). It's a small shop with 13 counter seats. Hours do change, so check the official site before you go.
- Standard Hokkyoku is the spice served straight, with minimal toppings. The veggie version is the same fiery broth with a mountain of stir-fried vegetables on top. Both go up to 10x, and both come with 1.5 portions of noodles as standard.
- "10x" is not the same as spice level 10. Hokkyoku already sits at the top of the shop's spice scale, and 10x adds the maximum extra heat on top of that. Longtime fans often say 2x to 3x is the sweet spot for actually tasting the bowl — so 10x is firmly hobby territory.

Hours and access for the Hashimoto branch
The Hashimoto branch is roughly a 10-minute walk from Hashimoto Station. That's a bit of a hike, but I ride there on my motorcycle, so it doesn't bother me.
It's open 11:00–15:00 and 17:00–21:00, closed on Mondays (if Monday is a holiday they open and close the Tuesday instead). Inside there are 13 counter seats plus one table for two — compact, and always clean.
As for crowds, combining my own experience with recent reviews: you may find a few groups waiting right before the lunch opening, but late afternoon and the hour before closing are often easy to walk into. It's not the constant queue you'd see at a famous Tokyo shop.
One thing worth knowing: limited-time menu items rotate monthly. If there's a specific seasonal bowl you're after, check the official site first.
Hokkyoku vs the stir-fried veggie version
Here's how I'd sum up the difference, having eaten both.
| Hokkyoku Ramen | Veggie Hokkyoku | |
|---|---|---|
| Broth | Fiery miso Hokkyoku broth | The same broth |
| Toppings | Minimal — bean sprouts and pork | A mountain of stir-fried vegetables |
| What you notice | Noodles and raw chili heat | Crunch and wok aroma |
| Max spice | Up to 10x | Up to 10x |
| Noodles | 1.5 portions standard | 1.5 portions standard |
| In a phrase | Heat in a straight line | Heat with peaks and valleys |
The standard Hokkyoku is the spice laid bare. Everything unnecessary has been stripped away so the heat hits you directly. When I had it at 10x last time, the only thing that really stayed with me was the sheer outline of "that was hot."
The veggie version pours that same broth over a pile of freshly stir-fried vegetables. The backbone of the heat is identical, but the crunch, the sweetness and the toasted wok aroma turn it into a completely different experience at the same 10x.
Why did I come back to the veggie one? Probably this: I'd rather have heat I can taste than heat that just hurts. Something about turning 50 has changed how I want to meet spice.
How hot is the veggie Hokkyoku at 10x?
First, an important note: "10x" doesn't mean spice level 10. Hokkyoku already sits at the top end of the shop's scale. 10x means adding the maximum extra heat on top of that.
Longtime fans often say 2x to 3x is where the bowl actually tastes its best. So 10x isn't about the optimal flavour — it's about visiting the edge. I honestly wouldn't recommend it for a first visit.
When it arrives, all you see is red. But there's a mountain of stir-fried vegetables sitting on top, and the yellow of the boiled egg reads like a small mercy. It looks dangerous and delicious at once, and that contradiction is exactly what Nakamoto is.
It's hot from the first mouthful. But the crunch of the cabbage and bean sprouts gives the heat something to land on, so it eats quite differently from the noodles-only version. The heat stacks up as you go, and by the second half the 10x shows its real face. Even then, the miso depth and the wok aroma stay with you — so you reach for water, and then immediately for the next mouthful.
I'll admit it: I still feel a little embarrassed saying "10x, please" at my age. But if I'm going to ask for it, I'm finishing the broth. That's the deal I make with myself every time. Thank you, chef.
Finishing the bowl, and the ride home
Finished it again, broth included.
To be honest, I didn't come because I was hungry. I came for the stress relief — the way some people go to a theme park. The same feeling I had when I took on the full-topping challenge at Ramen Jiro. Even in your 50s, it's worth keeping something you can throw yourself at.
The craving hits every so often. All right — more often than "every so often." I like spicy food to a degree that probably isn't entirely healthy.
Walking out afterwards, I got on the bike feeling completely cleared out. It was a brutal midsummer headwind, and yet it felt like a cool breeze across my face. Something close to floating.
I'll be back. Even if my backside pays for the ride.

Final thoughts
Veggie, then standard, then veggie again. Lining up those three visits, I finally understood what I'm actually chasing. It isn't the extreme heat itself — it's finding out how much flavour survives at the extreme.
It hurts, and I want it again. I finish drenched in sweat, and the ride home feels wonderful. That contradiction is hard to explain to anyone who hasn't sat at that counter.
You really don't need to go to 10x. Start with the regular Mouko Tanmen. That's more than enough to stand at the entrance to all that red.
