Differences between stores
The material states that the menu offered differs between stores.
The page's note says some listed items are sold only at certain stores, and some item names carry tags such as "for suburban stores," "store-limited" or "suburban stores only." The PDF version, opened from the "View as PDF" button, adds a separate list specific to the Yokohama-Tsunashima store; the table on the page does not include it.(machine translation)

- Notes for reading
The covered allergens are the 8 items Japan's Food Sanitation Act requires to be labeled, plus 21 recommended items (as the table's own heading counts them) -- 29 in all, with columns for both "matsutake mushroom" and "macadamia nuts." However, the note under the table lists the recommended items as 20 (without macadamia nuts there), which does not match the table's columns. The PDF version, opened from the "View as PDF" button at the bottom of the page, is dated 14 September 2026, has 28 columns (no macadamia nuts) and includes a separate list for the Yokohama-Tsunashima store. The page and the PDF may disagree, so a store must be asked about any item where the difference matters to you. Separately from what the table's marks show, two notes apply to the whole document: (1) the chain says trace amounts of other specified ingredients may get mixed in during factory production or in-store cooking/plating; the specific shared equipment or process is not named. (2) The chain states that its frying oil contains pork and soybean. Drink items are not included in this list.

対象は、食品衛生法で表示が義務づけられている8品目と、表示が推奨されている21品目(表の見出しの数え方)の計29品目で、「まつたけ」と「マカダミアナッツ」の両方の列があります。ただし表の下の注記は推奨品目を20品目として挙げており(そこにはマカダミアナッツがありません)、表の列とは食い違っています。ページ下部の「PDFで見る」から開けるPDF版は作成日が2026年9月14日で、列は28品目(マカダミアナッツなし)、横浜綱島店専用の一覧を含みます。ページとPDF版で内容が食い違うことがあるため、食い違いが気になる品目は店舗への確認が必要です。表の印とは別に、次の2点が全体にかかる注記として書かれています: (1) 工場での製造時や店舗での調理・盛り付けの際に、他の特定原材料が微量混入する場合があるとしていること。共有される具体的な設備・工程は特定されていません。(2) 「当店の揚げ油には豚肉・大豆が含まれております」としていること。この一覧にドリンクメニューは含まれていません。

How to read the symbols
The original document uses the symbols below. Our table shows the original symbol next to items with possible cross-contact.
| How it appears | Meaning |
|---|---|
| ● | Below the table, the page says that items marked with ● contain that ingredient (「●印の原材料が含まれております」). The mark shows that the item contains the ingredient. Show the original表の下に「●印の原材料が含まれております」と書かれており、●は、その商品にその原材料が含まれていることを示します。 |
| ー (our reading) | The document does not define this symbol (the long-vowel mark "ー"). The table has a dedicated column for every one of its 29 covered items, and this "ー" is printed uniformly in every cell that does not carry ●, so this site reads it as "not used as an ingredient" -- our own judgment based on the table's structure, not a guarantee against unintended trace cross-contact.Show the original文書はこの記号(長音記号「ー」)の意味を明記していません。表は29品目すべてに専用の列を持ち、●(含む)以外のマスには一律にこの「ー」が印字されているため、当サイトの判断として「原材料として使用していない」ものとして読み取っていますが、これは表の構造から当サイトが行った判断であり、意図しない微量混入がないことを保証するものではありません。 |
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”.
Details
Allergy notes
The official site's "Allergy information" page carries a per-item table. It is split into ramen, tsukemen (dipping noodles), rice dishes, side dishes, toppings, kids' items, desserts, seasonal items and Muslim-friendly items, and shows for each item whether each of 29 allergens is used: the 8 mandatory items plus 21 recommended items (there are columns for both "matsutake mushroom" and "macadamia nuts"). There is a single mark, meaning "contained"; every cell without it carries a different, uniform symbol. Separately from what the marks show, the page notes that trace amounts of other specified ingredients may get mixed in during factory production or in-store cooking/plating, and that the frying oil contains pork and soybean. Some items are sold only at certain stores. The page says that information is updated from time to time as products change, and asks customers to take note.
