Japan Allergy Dining Guide: Navigating Food Restrictions

Common Allergens in Japan

Japan’s food labeling law mandates declaration of seven major allergens: egg, milk, wheat, buckwheat (soba), peanut, shrimp, and crab. These are printed on all packaged foods and increasingly on restaurant menus. Soy and sesame, while not among the mandatory seven, are recommended for labeling and appear widely. Cross-contamination is a significant risk at restaurants that cook multiple dishes on shared equipment, particularly teppanyaki grills and deep fryers.

Wheat appears pervasively in Japanese cuisine: soy sauce contains wheat, most noodles use wheat flour, tempura batter is wheat-based, tonkatsu breading uses wheat panko, and even rice crackers sometimes contain wheat. For celiac travelers, tamari soy sauce (wheat-free) exists but must be specifically requested. Gluten-free restaurants are emerging in Tokyo and Kyoto, searchable through the Gluten Free Restaurant Card website and app.

Communicating Restrictions

Allergy communication cards printed in Japanese, available from websites like Just Hungry and the LiveJapan allergy card generator, clearly list your specific allergies in text that restaurant staff can read immediately. The Irusu allergy card app provides customizable cards covering all major allergens. Showing the card when ordering is more effective than verbal communication, as written Japanese eliminates misunderstanding risk.

Convenience stores provide the safest options for severely allergic travelers since all packaged products list ingredients and allergens clearly. Onigiri ingredient labels use standardized format. Hotel breakfast buffets with labeled items allow safe selection. When dining at restaurants, asking the specific question kore ni [allergen] wa haitte imasu ka (does this contain [allergen]) helps, and most restaurant staff will check with the kitchen if uncertain.

Allergy Communication

Japanese food labeling law requires manufacturers to list seven specific allergens: wheat, buckwheat (soba), egg, milk, peanut, shrimp, and crab. An additional 21 items are recommended for labeling. Restaurant menus increasingly display allergy information, particularly at chain restaurants. The most effective tool is a printed allergy card in Japanese listing your specific allergens, available for free download from multiple travel websites. Show this card to restaurant staff before ordering. Soy allergy presents significant challenges since soy sauce appears in virtually every savory Japanese dish, and avoiding it requires seeking restaurants that can prepare food without soy-based seasonings. Gluten sensitivity is manageable since rice is the dietary staple, but soy sauce contains wheat, and many fried foods use wheat batter. Tamari soy sauce, available at some restaurants, is wheat-free. Hotel concierges can help communicate complex dietary needs to restaurant staff by calling ahead.

Restaurant Strategies

Chain restaurants increasingly display allergy information on menus or provide allergy matrix charts listing the seven mandatory allergens for each dish. CoCo Ichibanya curry, Matsuya gyudon, and McDonald’s Japan all publish detailed allergy guides online. For non-chain restaurants, showing a printed allergy card in Japanese to the server before ordering is the most effective approach. Cards are available for free download from the Live Japan, Just One Cookbook, and Japan Travel websites. The phrase I used is “watashi wa [allergen] arerugii desu” (I have a [allergen] allergy). For severe allergies, calling restaurants ahead through your hotel concierge ensures the kitchen can prepare safe meals.

Specific Allergen Challenges

Wheat appears in soy sauce (shoyu), which is present in virtually every savory Japanese dish. Wheat-free tamari soy sauce exists but is rarely used in standard restaurants. Buckwheat (soba) allergy is taken extremely seriously in Japan and soba restaurants always ask about allergies. Peanut and tree nut use is relatively uncommon in Japanese cuisine compared to Southeast Asian food. Egg appears in tamagoyaki, tempura batter, and many baked goods. Shellfish including shrimp and crab features heavily in Japanese cuisine and appears in unexpected places like dashi stock, crackers, and furikake rice seasoning. For dairy-free needs, most traditional Japanese dishes naturally exclude dairy, but Western-influenced items like curry, cream croquettes, and bakery goods often contain it.
