- Notes for reading
This chart marks, dish by dish, which of the 28 designated allergens are used as ingredients with a "●" mark. We read an unmarked cell as "not used" based on how the table is built, but that is our own reading — the document itself does not explain what an unmarked cell means. The top of the chart notes that the allergen information is based on an ingredient survey and that materials not normally used in a product may adhere to it or mix in during manufacturing or in-store cooking. It also notes that stores boil soba and udon in the same pot, so if you have a soba (buckwheat) allergy, please be aware of possible cross-contact even when ordering udon. This chart has no columns for macadamia nuts or pistachio.

この一覧表は、そば・うどん・丼メニュー・各種セットなど品名ごとに、アレルギー物質28品目のうち原材料として使用しているものへ「●」の印を付けた表です。印のない品目については、当サイトでは表の作りから「使用していない」ものとして扱っていますが、これは当サイトの読み取りであり、資料自身がそう説明しているわけではありません。表の冒頭には、アレルギー情報が原材料の調査に基づくものであり、製造工場や店舗での調理の際に本来使用しない物質が付着・混入する可能性がある旨の注記があります。また、店舗ではそばとうどんを同じ茹で釜で調理しているため、そばのアレルギーがある方はうどんの品目を選ぶ場合でも混入の可能性にご留意ください。この一覧表にはマカダミアナッツとピスタチオの列がありません。
- Legibility notes
This chart is published as selectable PDF text rather than an image, but fitting 28 allergen columns onto one page makes the print quite small. We recommend zooming in when viewing or printing it.

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 |
|---|---|
| ● | Used as an ingredient.Show the original原材料として使用しています。 |
| (空欄) | The document does not define what an unmarked cell means. Because the chart gives each of the 28 allergens its own column, we read an unmarked cell as "not used as an ingredient" — this is our own reading rather than a statement by the document, and it is not a guarantee against unintended cross-contamination. Show the originalこの一覧表は空欄の意味を定義していませんが、アレルギー物質28品目それぞれに専用の列を設けたマトリクス表であるため、当サイトの判断として空欄を「原材料として使用していない」ものとして扱っています。資料自身がそう述べているわけではなく、意図しない混入(コンタミネーション)がないことを保証するものでもありません。 |
This document does not state, per symbol, the scope of possible cross-contact (a shared fryer, a shared line, and so on).
Details
Allergy notes
Komoro Soba publishes an official chart on its website listing, dish by dish — soba, udon, rice bowls and set meals — which of Japan's 28 designated allergens are used as ingredients. The chart does not explain what an unmarked cell means, but because it gives each of the 28 items its own column, we read an unmarked cell as "not used as an ingredient" (this is our own reading, not a guarantee against unintended cross-contamination). Stores boil soba and udon noodles in the same pot, so if you have a soba (buckwheat) allergy, please be aware of possible cross-contact even when ordering udon. The allergen information is based on an ingredient survey, and the chart notes that materials not normally used in a product may adhere to it or mix in during manufacturing or in-store cooking.

小諸そばは、そば・うどん・丼メニューなど品名ごとに、原材料として使用しているアレルギー物質28品目を示した一覧表を公式サイトで公開しています。印のない品目についてこの資料自体に説明はありませんが、品目ごとに列を設けた表であるため、当サイトでは「使用していない」ものとして扱っています(工場や店舗での意図しない混入がないことを保証するものではありません)。店舗ではそばとうどんを同じ釜で茹でているため、そばのアレルギーがある方はうどんの注文時にも混入の可能性にご留意ください。アレルギー情報は原材料の調査に基づくもので、製造工場や調理の際に本来使用しない物質が付着・混入する可能性がある旨も示されています。
