Okonomiyaki is one of the dishes gluten-free travelers cross off before they even land. The batter is wheat flour. The sauce is thick, sweet and usually built on things that contain wheat. And all of it cooks on one big communal griddle that has been running since lunch.
So a shop that has rebuilt the whole thing on rice flour is worth the trip across town.
Hiro is the Tokyo branch of a restaurant from Ashiya, Hyogo Prefecture, in the Kansai region where okonomiyaki and negiyaki are everyday food rather than a novelty. The Nakameguro store has been open since 2021, and the okonomiyaki here is described as being made with domestic rice flour rather than wheat.

The setting: a counter, a griddle, and someone cooking in front of you
The shop is a short walk from Nakameguro Station, on the ground floor of a building in the Higashiyama neighborhood. It is a griddle restaurant in the Kansai style, which means the cooking happens right in front of you and the room smells like it from the moment you open the door.
That visibility turns out to matter. When your food is being cooked a meter away, an allergy conversation stops being an abstract request to a kitchen you cannot see, and becomes something you can watch being handled.

What we ate
Pork okonomiyaki. Cabbage-heavy, properly thick, and the surprise was the texture: crisp fried bits worked through the batter that gave every bite a crackle against the soft interior. It is the sort of detail you do not expect to get back once you are eating gluten-free. The sauce is the shop's own and it is one of the gluten-free ones, so you get the full sweet-savory finish rather than a plain pancake. There is a garlic sauce as well, and it is worth asking for.

Beef sinew yakisoba. Chewy, bouncy noodles with a generous pile of ingredients through them. It arrives lighter and cleaner than the sauce-drenched yakisoba most people picture, which we liked, and you can add sauce yourself if you want it heavier.

All okonomiyaki and yakisoba sauces are confirmed gluten-free (as of our visit).

While this is a rice-flour okonomiyaki restaurant, it is not a dedicated gluten-free establishment. Detailed allergy information is not listed on the menu, so you will need to check directly with the staff when ordering. At the time of our visit, we were told that aside from dishes using soy sauce (such as negiyaki, beef sinew, and new onion salad) and the baguette for the French toast, the rest of the menu was gluten-free. Please note this was the situation at the time of our visit; be sure to confirm with the staff based on the severity of your allergy.
The Staff's Response When we mentioned the wheat allergy, the staff thoroughly wiped down the griddle before cooking and went through the menu with us to point out what to avoid. The owner is incredibly kind, assuring us that we could ask as many questions as we needed and actively encouraging us to speak up about our allergies without hesitation.
The Honest Summary Because the griddle is shared and soy sauce is used in the kitchen, those with celiac-level sensitivity need to have a clear conversation with the restaurant before sitting down to see if they can be accommodated. The printable Japanese allergy cards in our Tokyo guide are made exactly for this purpose. Since Komemaru has a mild wheat allergy rather than celiac disease, they were able to enjoy a very satisfying meal here.

What we loved
- The texture is the whole point. Crisp edges, soft middle, and fried bits running through it. This does not eat like a substitute
- Watch out for soy sauce, not just flour. As long as you avoid the few dishes that use it, you can safely enjoy most of the menu!
- Staff who invite the question. Being told to say it as many times as we needed is a small thing that changes the whole meal
Good to know
- Say it at the start. The griddle wipe-down has to happen before your food goes on, not after
- Watch for soy sauce, not just flour. It is the ingredient that quietly rules out dishes here
- Location: Higashiyama 1-3-3, on the ground floor of the Ars Nakameguro building, a walk from Nakameguro Station
- We have not visited the original Ashiya restaurant, so we cannot say whether the gluten-free handling there is the same
Nearby: how to fit it into your day
- The Meguro River path starts a few minutes away, and the walk between Nakameguro and Ikejiri-ohashi is one of the nicest in the city outside cherry blossom season
- Nakameguro's back streets are full of small shops and coffee, which makes this an easy dinner after an afternoon of wandering
- Shibuya is just a short train ride away, making Nakameguro the perfect place to escape for a quiet dinner after a busy day in the city.
The bottom line
Okonomiyaki is a dish gluten-free travelers usually watch other people eat. At Hiro the batter has been rebuilt in rice flour, the sauce is safe, and the person cooking it will wipe the griddle for you if you ask. Order the pork or seafood (shrimp, squid, octopus) okonomiyaki, skip anything with soy sauce in it, and enjoy a dish most of us had written off.
