Franchise
Not a list of the whole menu. All 9 allergens Japan requires can be checked for what is listed. Plus 19 recommended items, excluding Pistachio. (Eggs, Milk, Wheat, Buckwheat, Peanuts, Shrimp, Crab, Walnut, Cashew Nuts) We checked the material on the official site in October 2026; it may have changed since.
This page is an entry point we compiled from officially published information. Always make your final check against the official source.
Covers 28 items (pistachio not covered), this document covers part of the menu and points elsewhere for the rest
What is stated about severe allergies
Ichiran says it takes great care during manufacturing and in-store preparation, but that trace amounts of other allergens may get mixed in. Because sensitivity to allergens varies from person to person and even trace contamination can cause symptoms, it asks anyone who is concerned to consult a specialist doctor and then decide for themselves.(machine translation)

製造や店舗での調理の際には細心の注意を払っているものの、他のアレルギー物質が微量混入する場合があるとしています。アレルギー物質への感受性には個人差があり、微量の混入でも発症する可能性があるため、心配な場合は専門医に相談したうえで、ご自身で判断するよう案内しています。
Choose the allergens you need to avoid. The table starts with the items Japan requires to be declared; choosing narrows it to yours and says whether this document can answer for them.
Choose your allergens and we will prepare a Japanese sentence to show to the staff.
Items this table cannot answer for
This document covers only 28 of Japan's 29 listed items. The other 1 — including Pistachio — cannot be checked here.
If you avoid any of these, this table cannot answer for you — please check with the restaurant directly before visiting.
In addition, this document's table has no column for Celery, Lupin, Mustard, Sulphur Dioxide and Sulphites — items that EU, International (Codex) require.

- Notes for reading
The table is on the allergy information page that opens from the ramen page of the official site; souvenir products are not covered. The top of the page says the information is shown "based on the 8 specified raw materials in Japan", but the table has columns for 28 items: the 8 specified raw materials and 20 others. ● means the dish contains the item. ※1 means the item is not used as an ingredient, but the dish is made in the same place as other products. △ is the mark of a note about the waters where the nori is harvested; it appears only in the crab and abalone columns of the nori row. On the same nori row, ※1 appears in the columns for the other species the note names (shrimp, squid, salmon, mackerel) and in the wheat, milk, egg, beef, soybean, chicken, pork, gelatin and sesame columns. The document does not say what × means. It fills every cell that carries none of ●, △ or ※1, and this site reads it as a mark that the item is not used as an ingredient. ※2 to ※4 after a dish name mean that the item is the one of the stores that serve, respectively, Classic Tonkotsu Ramen (Since Founding) / Gokaku Ramen / Ra-Mugi noodles, Kamadare Tonkotsu, and 100% Tonkotsu-Free Ramen. Notes such as 【一蘭の森 糸島店】 (Ichiran no Mori Itoshima store), 【キャナルシティ博多店】 (Canal City Hakata store), 「御堂筋店のみ」 (Midosuji store only) and 「キャナルシティ博多店は除く」 (except the Canal City Hakata store) show which stores carry the dish.

The official site also has a machine-translated English page, but its marks and dish names differ from the Japanese page (for example ● is shown as "v" and × as "-"). This site's table uses the marks of the Japanese page.
