The packaging carries a legally required allergen declaration
Packaged processed foods are required by law to declare their ingredients and allergens, so you can check on the product itself.
As of August 2026 we could not find a per-product list published online. To check before you go, use the online shop or the contacts below.
The declaration is mandatory for Japan's designated allergens; whether the recommended items are listed is up to each company. Items packed to order or sold loose are outside the requirement.
No allergen list or allergen search page is published for the food served in the restaurants.(machine translation)

How you are told you can check
No allergen list or labelling is published for the udon, soba and set meals served in the restaurants. Some of the bagged products sold for delivery do state the allergens they contain (as of August 2026, only some of the products). That labelling is about the packaged goods that are shipped, however, and does not tell you what goes into the dishes served in the restaurants. For the restaurant menu, please ask the staff directly when you visit.(machine translation)

Differences between stores

Found an error in the allergen information?
Please tell us if anything here differs from the official information. Safety-related reports take priority, and we hide the affected entry until we have checked it. If you are about to eat, please check with the venue rather than waiting for us.
