READ THIS BEFORE YOU NEED IT

Useful before the trip—and in the moment.

For International visitors preparing for or travelling in Japan

Before you go

Read this before the issue becomes urgent. Save the key address, rule or phrase so it still works when your connection or attention is limited.

In Japan

Use only the first action and the section matching your situation. Current official instructions take priority over this general guide.

Picture this

A noodle bowl looks vegetarian, but you cannot tell what is in the broth or shared fryer. Name the ingredient and cross-contact risk before staff begin preparing the order.

A dish that appears suitable can contain stock, sauce or seasoning made from an unexpected ingredient. For a serious allergy, staff must confirm the ingredients and preparation method.

Do this first

List each ingredient you must avoid in Japanese.
Ask about stock, sauces, garnishes and shared frying oil.
State whether traces or shared equipment are unsafe for you.
Do not eat the dish if the restaurant cannot confirm.

What to expect in Japan

Vegetarian does not always mean that fish stock is absent.
Menus and staff knowledge differ between branches of the same chain.
A translation card supports a conversation; it does not certify that a dish is safe.

04 · A REAL TRAVEL MOMENT

The hidden ingredient is often in the seasoning

A bowl looks like vegetables and noodles, but the broth may contain fish, meat or another allergen. Pointing only at the visible topping is not enough. Name the ingredient, explain whether shared oil or equipment is unsafe, and give staff permission to say they cannot confirm.

Japanese food becomes more interesting when you notice that flavour can be built through stock, fermentation, sauces and seasonal garnishes—not only the main ingredient. The same complexity that makes a dish memorable also makes a precise allergy conversation important.

Take this practical check into a real journey.

After the immediate check, use the long-form journey guide to connect time, movement, the route home and what to do when the plan changes.

When staff and traveler cannot understand each otherReduce the conversation to one task, show the evidence that matters and use situation-specific Japanese for stations, restaurants, hotels and shops.
