Allergen Chart for Restaurants

Site menus often lack an allergen field, so shops keep a separate sheet and update both by hand. Rather than a tag such as vegan or gluten-free, this app adds a chart of every dish against every allergen: contains, does not contain, or not entered yet. Japan's 29 items are set up, checked against the Consumer Affairs Agency list as of April 2026 (9 mandatory, 20 recommended; checked 2026-10-29). Shops fill it in on a dashboard page. On the site each dish is a card with pictograms: contained items are filled red, and items not yet entered show "?", so a blank is not read as "does not contain". Guests can filter out allergens to avoid and switch Japanese/English and light/dark. A table below the cards prints all dishes. Free covers the Japan list and up to 30 dishes. Pro adds the EU and US lists, up to 1,000 dishes, CSV export, print view, larger text and a menu rename/removal check. Nothing is detected automatically: the shop enters allergens by hand or CSV, and dish names can come from the site's restaurant menu. A notice above the cards that cannot be hidden says the shop is responsible for its entries. The app does not judge any law. Staff take questions about food allergies.
