How to Book a Restaurant in Japan With a Food Allergy
2026-08-05
Japan is one of the best places in the world to eat — and one of the trickier places to book a table if you have a food allergy and don’t speak Japanese. Many of the best restaurants don’t take online reservations, and “no problem” at the door can mean something different than you expect. Here’s how booking really works and how to make sure your allergy is understood, not just heard.
Why you often still have to call
Big chains and hotel restaurants take online bookings, but a huge share of Japan’s most rewarding places — the neighborhood izakaya, the counter sushi spot, the ryokan kaiseki dinner — still run on phone reservations. Some use platforms like Tabelog or a LINE account, but plenty simply expect a call, especially for same-week bookings or anything involving a special request. If you only book what’s online, you miss much of the good stuff.
Allergies get lost in translation
A polite Japanese “daijōbu” (it’s fine) sometimes means “we heard you” rather than “we can guarantee it.” Cross-contamination isn’t always understood the way it is elsewhere, and some ingredients hide in plain sight — dashi (fish stock) is in an enormous number of “vegetarian-looking” dishes, and soy, wheat, and bonito turn up almost everywhere. Naming the allergen clearly, stating the severity, and asking specifically whether the dish or broth contains it makes a real difference.
How to communicate it clearly
- アレルギーがあります (arerugī ga arimasu) — “I have an allergy.”
- 〇〇を食べられません (〇〇 o taberaremasen) — “I can’t eat 〇〇.”
- Ask directly: この料理に〇〇は入っていますか? — “Does this dish contain 〇〇?”
Bring an allergy card (a printed note in Japanese listing your allergens) to show at the table as backup. But the reservation call is where you set expectations — a restaurant that can’t accommodate you would much rather know before you arrive.
When you want it handled for you
For a high-stakes meal — a birthday, a once-in-a-trip ryokan dinner, a serious allergy where a misunderstanding isn’t an option — it’s worth having a native speaker make the call. We book the table, state your allergy and its severity plainly, confirm the restaurant can actually accommodate it, and send you the details in writing. Ten minutes on our side can save the whole evening.
