Food Allergies in Japan: How Travelers Can Ask Restaurants Safely

Travelers with food allergies should show written allergy information before ordering and confirm sauces, soup stock, seasonings, and cross-contact.

If you have a food allergy and want to eat out in Japan, the quick answer is:

Prepare a written allergy card, show it before ordering, and ask whether the restaurant can safely confirm ingredients. Do not rely only on photos, menu names, or translation apps. Packaged foods may have allergen labels, but restaurants may not always have complete allergy information, and cross-contact can still happen.

If you have a history of severe allergy or anaphylaxis, keep your emergency medicine with you and know how to call 119 in Japan.

Show This First

English meaningJapanese to show
I have a food allergy.食物アレルギーがあります。
I cannot eat this ingredient.この食材は食べられません。
Is this ingredient used in this dish?この料理にこの食材は使われていますか?
Is it used in the soup, sauce, seasoning, or broth?スープ、ソース、調味料、だしに使われていますか?
Is there a risk of cross-contact in the kitchen?調理中に混ざる可能性はありますか?
If you are not sure, I will not eat it.分からない場合は食べません。
Please call an ambulance.救急車を呼んでください。

Write your exact allergen names in Japanese on your own card before the trip. A printed card is often clearer than speaking only in English.

Packaged Food vs Restaurants

Japanese packaged processed foods have allergen labeling rules. Look for words such as:

  • アレルゲン = allergen
  • 特定原材料 = specified allergenic ingredients
  • 原材料名 = ingredients
  • 含む = contains

As of April 2026, Japan’s mandatory allergen labeling for packaged processed foods includes egg, milk, wheat, buckwheat/soba, peanut, shrimp, crab, walnut, and cashew nut. However, labeling changes can have transition periods, and older packages may still exist.

Restaurants are different. A menu may not list every ingredient, sauce, broth, oil, topping, or kitchen cross-contact risk. If the staff cannot confirm, choose a safer option.

The Consumer Affairs Agency and Tokyo Metropolitan Government provide food allergy communication sheets that travelers can download and use.

Japanese Foods That Need Extra Checking

Food or situationWhat to check
SobaSoba means buckwheat. Soba restaurants may also prepare other noodles in the same kitchen
Ramen, udon, tempura, okonomiyakiWheat, egg, seafood, broth, sauce, and shared fryers may matter
Dashi / soup stockMay contain bonito, fish, shellfish, kelp, or other ingredients depending on the dish
Soy sauce, miso, saucesSoy and wheat are common label checks
Sushi and seafood restaurantsFish, shellfish, roe, soy sauce, wasabi mixtures, and shared tools may matter
Desserts and breadEgg, milk, wheat, nuts, gelatin, and sesame may appear
Buffets and izakayaShared utensils and mixed menus can increase cross-contact risk

Do not assume vegetarian, vegan, halal, or “no meat” also means allergy-safe. Those labels are about dietary style, not always kitchen allergy control.

For vegetarian and vegan wording issues in Japan, JNTO also recommends being specific about what you cannot eat.

Safer Habits While Traveling

  • Contact restaurants in advance for reservations or set menus.
  • Use an allergy card with Japanese text and simple icons if possible.
  • Choose restaurants that can clearly answer ingredient questions.
  • Keep safe snacks or packaged foods as backup.
  • Check convenience store and supermarket labels carefully.
  • Avoid complex dishes if the staff cannot confirm the ingredients.

When to Get Emergency Help

Call 119 in Japan or ask someone nearby to call if there is trouble breathing, throat tightness, swelling of the lips or face, repeated vomiting, dizziness, collapse, confusion, or symptoms involving multiple body areas after eating.

If you carry prescribed emergency medicine, follow the instructions you were given by your own doctor.

Bottom Line

For food allergies in Japan, the safest simple plan is:

  1. Prepare a written allergy card in Japanese.
  2. Show it before ordering.
  3. Ask about sauces, soup stock, seasonings, toppings, and cross-contact.
  4. Use official allergy communication sheets when helpful.
  5. If the restaurant cannot confirm, do not eat the dish.

Japanese food can be a wonderful part of travel, but allergy safety depends on clear communication and choosing places that can answer clearly.
