About Japanese Restaurant Chain Nutrition Almanac
How this database is built, who runs it, and how to read the dietary tags responsibly.
The Japanese Restaurant Chain Nutrition Almanac (food-db.work) is a non-commercial calorie and nutrition reference for the menu items at major Japanese restaurant chains, cafés and convenience stores. It is built and maintained by a small editorial team based in Tokyo. We rebuild the database every week from each chain’s official nutrition data, so the figures you read here are not guesses, not scraped from community wikis, and not aggregated from social media.
The English edition exists for two audiences: foreign residents in Japan who need to navigate menus they cannot read, and short-stay travelers who need to make food decisions on the ground without spending an hour translating each menu item. We focus on the chains visitors actually encounter — the gyudon trio, McDonald’s, Starbucks, the major konbini, sushi belts, and family restaurants — rather than trying to cover every chain in Japan from day one.
For each menu item we publish per-serving calories, protein, fat, carbohydrates, salt and (where available) sodium, dietary fiber, sugar, saturated fat, caffeine, and alcohol. We attach a best-effort dietary classification: vegetarian, vegan, pescatarian, halal-friendly, gluten-friendly, low-sodium, and high-protein. These classifications are derived from the menu name and category and are advisory only — they are not certifications. Each item page links to the chain’s own page for verification, and each dietary filter page explains its specific limitations.
