How they handle allergies
Allergy notes
Each product page on the official site carries a table of the 28 specified and recommended allergen items for that product. For products that come with a dressing or sauce on the side, separate marks show whether an allergen is in the food itself or in the accompaniment, and products with two accompaniments use three different marks. Each table carries its own date, and depending on the product that date ranges from a few weeks to several years ago. Some products are not shown on the website, and for those the chain answers enquiries.

表の上に名前が挙がっている2つ目の別添に含まれます。 - Blank: the marks sit in a fixed position per component, and the position is left empty when that component does not contain the item. We read an empty position, and an item with no mark at all, as meaning the item is not used. The document does not state this reading, so it is ours, and it is not a guarantee against traces picked up in preparation.

印は構成要素ごとに位置が決まっており、その構成要素に含まれない場合はその位置が空いたままになります。空いた位置と、印が1つも付いていない品目について、当サイトはその品目を使用していないという意味に読んでいます。資料はこの読み方を説明していないため当サイトの判断であり、調理や製造の過程で混入しないことの保証ではありません。
No scope of possible cross-contact (a shared fryer, a shared line, and so on) is recorded for this document's marks. The scope may be given in the document's notes or under “Notes for reading”.

- How to use it
Only part of what the shops sell is listed. For the allergens of products not shown on the website, and for which shops carry them, the chain asks you to enquire giving the product name and the items you want to know about. The range stocked differs from shop to shop. Product pages state a selling period. Pages whose period has ended stay up and can still appear in the lists, so check the selling period of the product you are looking at. Above the table the chain writes that product contents may change and asks you to check again in the shop when you buy.

掲載されているのは店舗で扱う商品の一部です。ホームページに載っていない商品の特定原材料や、その商品を扱う店舗については、商品名と知りたい項目を添えて問い合わせるよう案内されています。取り扱い商品は店舗によって異なります。商品ページには販売期間が書かれています。期間が終わった商品のページもそのまま残り、一覧に並んでいることがあるので、見ている商品の販売期間を確かめてください。表の上には、商品内容は変更される場合があるので購入時に店頭で再度確認するよう書かれています。
- Notes for reading
The product list is split into salads, fish dishes, meat dishes, fried foods and others. The 「特定原材料等」 section of a product page holds the table of 28 items. Besides those 28 the table has a column for 「魚介類」(fish and shellfish in general). For products that come with something on the side, the names of the accompaniments are listed above the table ("the product only", "the such-and-such dressing only"), each with its own mark used in the table; a product with two accompaniments uses three marks. Products with no accompaniment carry no key and use a single mark. Each mark has a fixed position for its component, so the position of a component that does not contain the item is left empty. Each table is dated underneath, and depending on the product that date ranges from a few weeks to several years ago, so check the date on the product you are looking at.

商品一覧はサラダ・魚料理・肉料理・揚げ物・その他に分かれており、各商品ページの「特定原材料等」の欄に28品目の表があります。表には28品目のほかに「魚介類」の欄があります。ドレッシングやソースが別添される商品では、表の上に「本体のみ」「◯◯ドレッシングのみ」のように別添の名前が並び、それぞれに対応する印が欄に付きます。別添が2種類ある商品では印が3種類並びます。別添のない商品には印の説明が無く、1種類の印だけが使われます。印は構成要素ごとに位置が決まっているので、含まれない構成要素の位置は空いたままになります。表の下には商品ごとに日付が入り、数週間前のものから数年前のものまで商品によって異なるので、見ている商品の日付を確かめてください。
- Legibility notes
The containment marks are small images with no text label, so they are not conveyed by a screen reader. Which mark stands for which component is printed above the table on products that come with an accompaniment. Products without one (about half of those listed) carry no such key, and the single mark used there stands for the product itself.

含有を示す印は小さな画像で、文字の説明が付いていないため、読み上げでは伝わりません。印と構成要素の対応は、別添がある商品では表の上に印字されます。別添のない商品には対応の説明がなく(掲載商品のおよそ半数)、その場合に使われる印は1種類だけで、商品そのものを指します。

- ※ About the information on this page
- This site collected and organised this page from documents the company publishes. We cannot guarantee it is accurate or current, and it is not medical advice. Before you eat, check with the restaurant or its official information.
- ※ This site's reading
- Marks with a ※ are not defined by the document; this site read them from how the table is built. For example, an unmarked cell is read as "does not contain" — the document does not say so, and it is not a guarantee against unintended cross-contact.
- ※ Document dates
- The source check date records our check on the official site, not a review of every listed value or a safety assessment. The material may have changed since. “Source date: not recorded” does not establish whether the source is undated.
- ※ What this page covers
- This page carries food-allergen labeling information. Gluten-free claims and religious dietary exclusions are decided by different criteria.
- ※ Differences between stores
- We have not yet established whether things differ between stores. That is not a statement that they do not.
