Be able to clearly tell a restaurant which foods you cannot eat, understand the limits of what the restaurant can do, decide for yourself whether to eat, and call 119 if you have strong symptoms.
Explanation
In Japan, there are allergen labeling rules for packaged processed foods, but restaurants are not required to label the dishes they serve. Some restaurants provide information voluntarily, but the absence of a label does not mean that an ingredient is not in the food.
Before ordering, say clearly which foods you cannot eat, for example: "Shokumotsu arerugī ga arimasu. Tamago o tsukatte imasu ka?" (食物アレルギーがあります。卵を使っていますか, "I have a food allergy. Does this contain egg?"). If it is difficult to explain in Japanese, you can also show a card with the names of the foods written on it. However, small amounts can get mixed in, for example through shared cooking equipment, and there are limits to what a restaurant can do. If you have a severe allergy, contact the restaurant in advance to check whether they can accommodate you, and if you have any concerns, consider not eating there. In the end, it is you (or your family), not the restaurant, who decides whether to eat.
If you have strong symptoms after eating, such as difficulty breathing, do not hesitate to call 119 for an ambulance.

Frequently asked questions
Q. What if I cannot explain in Japanese?
A. You can use a card listing the foods you cannot eat, or a translation app. Some local governments, such as the Tokyo Metropolitan Government, publish sheets for communicating allergies in multiple languages and with pictograms.
Q. Can I just ask them to remove it from the finished dish?
A. Just removing it may leave small amounts behind. You can also ask whether they can make the dish again, but some restaurants cannot do this.
Q. Which ingredients must be labeled on processed foods?
A. There are 9 items: shrimp, crab, walnuts, wheat, buckwheat (soba), egg, milk, peanuts and cashew nuts. Cashew nuts were added in April 2026, and there is a two-year transition period, so some products may not show them yet. The list may be revised, so check the latest information from the Consumer Affairs Agency.
