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.
How you are told you can check
No allergen information is published for the ramen and other dishes served in the restaurants. Gift items you can order for delivery do list allergens for each product, but that is labelling for packaged goods and does not describe what is served in the restaurants. To ask about the restaurant menu, contact the Dosanko head office (phone 03-6311-8900, open daily 10:00-17:30) or the enquiry desk on the official site. Outside those hours the chain asks you to contact the individual branch directly.(machine translation)

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.
