FoodLens Japan: Menu & Allergy

About

Eat out in Japan with more confidence. Point your camera at a Japanese menu. FoodLens Japan translates every dish, explains what it is, and estimates the allergens and ingredients that are easy to miss — then helps you ask the staff in Japanese. CHECKED BY A PROFESSIONAL CHEF Japanese food hides ingredients you can't see: dashi is usually made from fish, soy sauce contains wheat, mirin is a kind of sake, and many dressings contain egg. The rules behind FoodLens were reviewed dish by dish by a professional chef. In our test on 25 real restaurant menus (504 dishes), FoodLens missed about 1.4% of allergens, and showed about 0.8% of dietary checks as fine when they weren't. We publish these numbers because no app is perfect — that's why FoodLens always sends you to the staff for the final answer. WHAT YOU GET • Menu translation into 12 languages: English, 简体中文, 繁體中文, 한국어, Français, Español, ภาษาไทย, Tiếng Việt, Bahasa Indonesia, Deutsch, Italiano, Русский • 11 allergen groups, including squid & octopus, fish-based dashi and oyster sauce • Vegetarian, vegan, halal-friendly (no pork, no alcohol) and pescatarian checks • Clear badges: red when a dish normally contains something, and "?" when it depends on the restaurant • A filter that hides dishes that don't fit your profile, and a search for big menus • Prices converted to your currency ASK STAFF — IN JAPANESE Tap Ask Staff to show a large Japanese question card, such as "Does this dish contain egg? (including dashi)". The first card tells the staff about your allergies. Staff can tap Yes / No / Not sure, and their answer is saved on the dish, so you both understand each other without a shared language.

IMPORTANT Allergen information is estimated by AI based on standard recipes and is not 100% guaranteed. Recipes differ between restaurants. Toppings, add-ons and self-service bars are not analysed. Always confirm with the restaurant staff before eating, especially if you have a severe allergy.
