Why allergies are difficult in Japan

Many Japanese dishes use hidden ingredients such as fish broth, soy sauce, wheat, egg, sesame, shellfish or dairy-based additions. Staff may be polite but not able to guarantee cross-contact or ingredient details in every restaurant.

Before the trip

Prepare allergy cards that list the allergen and severity in Japanese.
Save phrases and screenshots offline in case internet fails.
Research restaurants that publish allergen information or handle restrictions clearly.
Pack safe snacks for travel days, late arrivals and rural routes.
Know how to contact emergency services and your travel insurance if needed.

Restaurants and packaged food

Chain restaurants, hotels and larger stores may have clearer allergen information than small local restaurants, but policies vary. Convenience stores and supermarkets can be helpful because labels are visible, yet translation apps may misread small print or ingredient names.

For serious allergies, do not rely only on visual inspection. Ask, check written information and keep backup meals available.

Common mistakes

Checking only the main ingredient and ignoring broth, sauce or seasoning.
Assuming vegetarian food is automatically safe for allergies.
Depending entirely on real-time translation in a noisy restaurant.
Waiting until arrival to create allergy cards.
Eating when staff cannot confirm the ingredient information.
