How to Book a Vegetarian or Vegan Restaurant in Tokyo, Kyoto, or Osaka

Match the listing to the booking channel

Different listings lead to different booking paths. Some are only on a platform with no online booking, some have a Japanese-only form, and some only answer a phone call. The right next step depends on the listing you opened, not on a default that works for every restaurant.

What "vegetarian" in Japan can mean (dashi, katsuobushi, gokun)

A useful booking question is shaped by knowing what the kitchen is actually cooking with. The Japan National Tourism Organization (JNTO) and the Japan Tourism Agency's guidance for restaurants both flag the same traps, and the labels on a menu do not always surface them.

• Dashi: the foundational stock of Japanese cooking. It usually starts with kombu (kelp) and is finished with katsuobushi (bonito flakes) or niboshi (dried sardines), so it contains fish even when the dish looks plant-based. JNTO tells travelers to "say no meats, seafoods, or animal products including dashi or stocks" and to watch for bonito flakes on tofu, salads, and cold tofu dishes.
• Hidden fish: bonito flakes on top of hiyayakko (cold tofu) and okonomiyaki, dashi in the dipping sauce for cold soba and tempura, and dashi in the natto sauce sachet. The Japan Tourism Agency's substitution tables list bonito-based stock as the standard and a kombu-and-shiitake stock as the vegetarian replacement.
• Eggs and dairy: many Japanese set meals include tamago (egg), milk-based dressings, or butter in supposedly vegetable dishes. State them separately if you avoid them.
• Ponzu and soy sauce: most are vegetarian, but some ponzu contains dashi or fish extract. If it matters, ask the kitchen rather than trusting the bottle.

State your dietary need precisely

"Vegetarian" alone often gives the kitchen a different mental picture than yours. A written request that names each thing you avoid — including the stock — gives the kitchen a chance to answer for the specific dish on the day, rather than for "vegetarian food" in general.

• Whether you are vegan, vegetarian, pescatarian, or avoiding a specific ingredient or allergen.
• Whether dashi (kombu-only, kombu-and-shiitake, or bonito-based), katsuobushi, eggs, dairy, honey, or gelatine are OK or not.
• Whether cross-contact with meat, fish, eggs, dairy, soy, sesame, wheat, or a specific allergen is a concern for you.
• The reservation date, time, party size, and one backup time, so the kitchen can answer for the actual sitting.

If the restaurant says it cannot accommodate

If the answer for your date is "we cannot meet that need," do not push the same kitchen for the same sitting. Ask what it can offer instead and what it cannot change about its menu, then decide on that basis.

• Whether a different dish on the same menu would work, or whether the kitchen needs a different date to prepare something separately.
• Whether the kitchen can use kombu or kombu-and-shiitake stock instead of bonito for the reservation, and whether that change is even possible given its current menu.
• Whether the kitchen recommends a different restaurant for the same area that it knows handles the same diet, and the name of that place.
• If the answer is genuinely unclear or the kitchen only repeats the menu, treat the answer as "not safe for this reservation" rather than as a soft yes.

Cross-contact considerations

A restaurant that offers vegetarian or vegan options can still cook them in the same pan, the same oil, or the same griddle as fish or meat. Cross-contact matters if you have a severe allergy, a medical restriction, or a strict vegan reason to avoid animal products at the trace level. Ask the kitchen before you book, not at the table.

• Whether the vegetarian or vegan dish is prepared on a separate surface, with separate utensils, and in separate oil from meat and fish.
• Whether the kitchen can use a clean pot, pan, and ladle for dashi if you are avoiding bonito, and whether it has time to do so during your sitting.
• Whether the same kitchen handles allergens such as peanut, tree nut, sesame, soy, wheat, shellfish, or egg on the same line, if those matter for you.
• If cross-contact is the deciding factor, treat the answer as the deciding answer: do not infer safety from the menu's vegan or vegetarian label.

Copy-and-send message to the restaurant

Send this through the contact form, email, or Instagram DM shown on the restaurant's official site or its listing on HappyCow or Vegewel. Do not include payment-card details or passport images. Replace the brackets, keep the request to one screen, and add or remove lines to match your diet.

When a call helps

If the listing has no online booking, no English contact form, or you have tried and received no reply, a short Japanese phone call can confirm a table and relay your dietary question. The restaurant's answer is not a medical guarantee, so do not treat an uncertain answer as safe, and confirm any change directly with the kitchen on the day.

Our service policy

For restaurant reservations, we can place a phone call in Japanese to ask about availability, request a booking, or relay a dietary question, and report the restaurant's answer. The restaurant makes the final decision on availability, the dish, and whether it can meet the dietary need. You make the final decision on whether to keep the reservation. We do not make food-safety or allergen-safety decisions on your behalf.

Useful phrases if you call yourself

If you'd rather try the call yourself first, these phrases can help.

I'm vegetarian. I don't eat meat or fish.

ベジタリアンです。肉にくや魚さかなは、食たべません。

I'm vegan — no meat, fish, eggs, or dairy.

ヴィーガンです。肉にく、魚さかな、卵たまご、乳製品にゅうせいひんは、食たべません。

I don't eat meat, fish, or eggs.

肉にく、魚さかな、卵たまごは、食たべません。

Do you use dashi made from fish?

魚さかなから作つくった、だしを使つかっていますか？

Is this dish suitable for vegans?

この料理りょうりは、ヴィーガンに向むいていますか？

Can you check with the kitchen?

厨房ちゅうぼうにも、確認かくにんしてもらえますか？

Common questions

Does vegetarian food in Japan always exclude fish stock or dashi?

Do not assume so. State specifically whether dashi, katsuobushi, fish, eggs, and dairy must be avoided, and ask the kitchen about the planned meal or its current preparation. JNTO and the Japan Tourism Agency both flag dashi and hidden bonito flakes as the main trap for vegetarian travelers.

What should I ask when booking a vegan restaurant in Japan?

Ask about the booking first, then state each restriction that matters, such as meat, fish, shellfish, dashi, katsuobushi, eggs, dairy, honey, and gelatine. Ask the kitchen to confirm the stock it will use for the reservation, and whether cross-contact is a concern.

Can MORISTACK guarantee a meal is vegan or allergen-safe?

No. MORISTACK can place a call in Japanese, ask the kitchen your dietary question, and report the restaurant's response. The restaurant's answer is not a medical guarantee, and you make the final decision. We do not make food-safety or allergen-safety decisions on your behalf.

Should I look for English-speaking staff at a vegetarian restaurant in Japan?

It helps but is not a guarantee of safety. A Japanese-speaking caller can ask the kitchen the specific question in writing and read the answer back. Either way, confirm the dietary detail with the kitchen rather than relying on the menu or platform label.

What about Buddhist shojin ryori — is it always vegan?

Traditional shojin ryori is built on kombu and kombu-and-shiitake dashi, with no meat, fish, eggs, or dairy. Some modern shukubo (temple lodging) and shojin-inspired restaurants add eggs, dairy, or a small amount of katsuobushi, so do not assume the meal is vegan by default. If you need strict vegan, state it in writing and confirm with the kitchen.

What if the restaurant only has a Japanese phone number?

A Japanese-speaking caller can ask the kitchen the booking and dietary question, and report the answer back. MORISTACK can place this kind of call, but the kitchen's reply is the source of truth, and you decide whether to keep the reservation.
