Navigating Food Allergies in Japan: What Every Traveller Needs to Know
Key Insight
Japan mandates labelling for 8 allergens but 'vegetarian' dishes often contain fish dashi stock — carry a printed allergen card in Japanese for the safest dining experience.
📖 Explanation
Japan's 8 Mandatory Allergens
Japanese law requires packaged food to declare 8 core allergens: eggs (卵), milk (乳), wheat (小麦), shrimp (えび), crab (かに), peanuts (落花生), buckwheat (そば), and tree nuts (木の実). A further 20 items are recommended for disclosure. This means packaged supermarket and convenience store food is relatively safe to navigate with Google Translate.
The Invisible Problem: Dashi
The bigger challenge is restaurant food. The base stock of Japanese cuisine — dashi (出汁) — is made from dried bonito fish flakes (katsuobushi) and/or kombu seaweed. It flavours almost everything: miso soup, noodle broths, sauces, rice seasoning, and vegetable dishes. A plate labelled as a 'vegetable dish' or 'tofu soup' almost certainly contains fish. This catches vegetarians, vegans, and people with fish allergies off guard constantly.
The Allergen Card Strategy
The most effective approach is a printed allergen card (アレルギーカード) in Japanese listing everything you cannot eat. Show it to staff before ordering. Several free resources generate these cards: Equal Eats and AllergyTranslation.com produce Japan-specific cards in multiple languages. Download a PDF before travelling — you'll use it at nearly every restaurant.
Navigating Different Food Styles
Soba restaurants: high cross-contamination risk for gluten-free diners; buckwheat is the main ingredient but wheat noodles are often cooked in the same water. Ramen shops: pork bone and chicken broths are standard — ask for a vegan/vegetarian option only at specialist shops. Conveyor belt sushi (kaiten-zushi): chains like Sushiro have allergen menus on their tablet ordering systems with full disclosure.
Apps That Help
Google Lens on Japanese menus works well for general translation. Safeats Japan and HappyCow help locate allergy-friendly and vegan restaurants. Major convenience stores (7-Eleven, Lawson, FamilyMart) display full allergen icons on packaged food labels — these are your safest dining option in a pinch.
❓ Frequently Asked Questions
- Is Japan difficult for vegetarians and vegans?
- It is challenging, not impossible. Traditional Japanese cuisine is fish-forward even in vegetable dishes due to dashi. However, Buddhist vegetarian cuisine (精進料理, shojin ryori) is genuinely vegan, and major cities now have vegan-friendly restaurants. Convenience store onigiri and plant-based items are clearly labelled.
- Can I eat sushi if I have a fish allergy?
- Tamago (egg) and cucumber rolls are the fish-free options, but cross-contamination from fish handling is essentially unavoidable in any sushi restaurant. Inform staff via your allergen card — some sushi chains have allergen-filtered menus on their tablet systems.
- Where can I find allergen-friendly food easily?
- Convenience stores are the most reliable — all chains display allergen icons on packaged food. Conveyor-belt sushi chains (Sushiro, Kura Sushi) have full digital allergen menus. Hotel buffets are generally allergen-labelled at large international properties.
- How do I say 'I am allergic to X' in Japanese?
- The key phrase is: '私は[X]アレルギーがあります' (Watashi wa [X] arerugī ga arimasu — 'I have an [X] allergy'). However, showing a printed allergen card is more reliable than spoken Japanese in a busy restaurant.
