What is stated about severe allergies
Because the severity of a reaction can depend on the person and on the day, Saizeriya advises anyone who is highly sensitive or has severe symptoms to be especially careful, since even a trace amount of an allergen may cause a reaction.(machine translation)

Choose your allergens and we will prepare a Japanese sentence to show to the staff.

- How menus are ordered
- Listed by category
- How to use it
Seasonal items are on the menu for a limited time, so the table changes as the app is updated. The last-updated date is recorded from the date the app itself reports.

季節メニューは掲載期間が限られているため、アプリの更新に合わせて表の内容も入れ替わります。最終更新日はアプリが示す更新日を基に記録しています。
- Notes for reading
Because tableware and cooking utensils are shared, trace amounts of an allergen may be mixed in during preparation even for items with no ● (used) mark. The table also shows a reference column called "Seafood", which is not one of the legally specified or recommended ingredients, so it is not included among the 29 items this site tracks. Switching to English requires an in-app action; the URL itself carries no language parameter.

食器や調理器具を共用しているため、表に●(使用)の印がないアレルゲンでも、調理・提供の過程で微量混入する場合があります。また表には「魚介類」という参考項目がありますが、法令上の特定原材料・推奨品目のいずれにも該当しない項目のため、当サイトが追跡する29品目には含めていません。英語版への切り替えはアプリ内の操作が必要です(URLに言語を指定するパラメータはありません)。
- Legibility notes
The live page is a React single-page app that requires JavaScript to render. This site fetches the data directly from the JSON API the app itself calls.
