Ask about capability
Instead of demanding a substitution, ask whether the restaurant can safely serve you. A clear refusal may be the most responsible answer.

Eat with more confidence—and fewer assumptions
Use this page to prepare restaurant questions, dietary notes, payment options, and backup plans. Translation can help communication, but it cannot certify ingredients or prevent cross-contact.

Separate preference, religious restriction, intolerance, and medical allergy.

Check reservation, cancellation, last-order, and one-order-per-person rules.
- 06
Keep cash available even when a restaurant appears to accept cards.
- 07
Expect broths, sauces, garnishes, and shared equipment to contain hidden ingredients.

Save several nearby backup options instead of depending on one restaurant.

Keep the restaurant name and address ready to show staff or a taxi driver.

Decide, don’t just buy
A safer way to plan meals
Treat dashi as an ingredient
Stocks and sauces may contain fish, meat, soy, wheat, or other ingredients even when the visible dish looks suitable.
Packaged is different
Mandatory allergen labeling applies to certain packaged foods. Restaurant communication and cross-contact controls are a different situation.
Build a backup
Convenience stores, department-store food halls, supermarkets, and simple chain restaurants can provide alternatives when a planned meal fails.

Compare compact travel utensil sets
Look for a washable set with a secure case and only the pieces you will use. Treat it as a convenience item—not a way to manage food allergies or cross-contact.
Compare food-allergy translation cards
Choose cards that name exact ingredients and clearly distinguish an allergy from a preference. A card cannot guarantee ingredients or prevent cross-contact.
Compare pocket Japanese phrasebooks
Favor readable type, practical restaurant phrases, romaji or pronunciation help, and a format that works without a phone signal.
Compare compact food containers
Look for a secure, washable, leak-resistant container that fits your day bag. Check venue and transport rules before bringing outside food.
