Japan Food Allergies Guide: How to Eat Safely in a Country That Doesn't Speak Your Language

Japan's food scene is incredible — but navigating it with allergies requires preparation. Here's everything you need to know.

Understanding Food Allergies in Japan

Common Allergens in Japanese Food

The Dash Problem

Dashi is in almost everything. It's the base stock for most Japanese dishes, and it's usually made from:

• Katsuobushi (bonito flakes) — fish
• Kombu (kelp) — seaweed
• Shiitake mushrooms — fungi

If you're allergic to fish, you need to specifically ask for dishes without dashi.

How to Communicate Your Allergies

Allergy Cards

Essential tool for any allergic traveler.

Where to get them:

• Print before you go — websites offer free downloadable cards
• Custom cards — specify your exact allergens
• Restaurant cards — say "I cannot eat [X]"

Example card text:

``` 私は[材料]アレルギーがあります。 この料理に[材料]が含まれているかどうか教えてください。

Watashi wa [genryō] arerugī ga arimasu. Kono ryōri ni [genryō] ga fukumarete iru ka dō ka oshiete kudasai.

I have an allergy to [ingredient]. Please let me know if this dish contains [ingredient]. ```

Key Phrases

Communication Strategies

1. Show the card first — before ordering
2. Point to allergens — on the menu
3. Ask specifically — "Does this have [X]?"
4. Be persistent — if unsure, don't eat it
5. Carry snacks — just in case
