What is stated about severe allergies
Ootoya advises that sensitivity to food allergies varies greatly from person to person and that a reaction may occur depending on your physical condition at the time, so anyone who is sensitive should consult a doctor and decide for themselves.(machine translation)

Choose the allergens you need to avoid. The table starts with the items Japan requires to be declared; choosing narrows it to yours and says whether this document can answer for them.
Choose your allergens and we will prepare a Japanese sentence to show to the staff.
Items this table cannot answer for
This document covers only 28 of Japan's 29 listed items. The other 1 — including Pistachio — cannot be checked here.
If you avoid any of these, this table cannot answer for you — please check with the restaurant directly before visiting.
In addition, this document's table has no column for Celery, Lupin, Mustard, Sulphur Dioxide and Sulphites — items that EU, International (Codex) require.

- Listed by category
- Notes for reading
The table lists, beside each item name, icons for the allergens that item contains. An icon means the allergen is in that dish. Ootoya does not itself say what the absence of an icon means, but the listing declares its scope — allergen labelling covering the 28 items specified under Japan's Food Sanitation Act — and its per-dish listings are exhaustive, so we list an allergen with no icon as not used as an ingredient in that dish. That is a reading about ingredients, not a guarantee against cross-contact. The same item name can appear in both the Side Dishes and the Bento section with different allergens listed: the bento version adds what its condiment brings (apple from tonkatsu sauce on the fried items, wheat and soy from soy sauce on the plain ones), so we keep the two sections as separate rows rather than merging them. Set meal listings assume an order with white rice; switching to five-grain rice adds sesame. Ootoya states that it does not accept requests to change cooking methods on account of an allergy, or to change specific ingredients, seasonings or the like. Kitchen utensils, tableware, noodle-boiling equipment and frying oil are shared, so unintended cross-contact with allergens not shown for a dish is possible. The table is published per restaurant; the one shown here is for the Akihabara Ekimae location.

この一覧は、商品名の横に、その商品に含まれるアレルゲンのアイコンを並べる形式です。アイコンが付いている品目はその商品に含まれます。アイコンが無い状態の意味を大戸屋自身は書いていませんが、この一覧は「食物アレルギーの表示は、食品衛生法に基づき28品目を対象としています」と対象範囲を宣言しており、商品ごとの列挙も網羅的です。そのため当サイトでは、アイコンの無い品目をその商品の原材料としては使用していないものとして掲載しています。ただしこれは原材料についての読み取りで、混入がないことの保証ではありません。同じ商品名がサイドと弁当の両方に載っていて、記載されているアレルゲンが異なることがあります。これは弁当に付く調味料の分(揚げ物であればとんかつソースのりんご、そのままの料理であれば醤油の小麦・大豆)が加わるためで、当サイトでは畳まずに区分ごとに分けて掲載しています。定食のアレルギー表示は白米でご注文いただいた場合のもので、五穀ご飯に変更するとごまが加わります。アレルギーを理由とした調理方法の変更や、特定の食材・調味料等の変更のご要望はお受けできないとしています。厨房器具・食器・茹で麺機・揚げ油を共有しているため、表示のない品目についても意図しない混入の可能性があります。この一覧は店舗ごとに公開されており、ここでは秋葉原駅前店のものを掲載しています。

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 |
|---|---|
| (空欄) | This listing has no column per allergen — it shows icons for the allergens a dish contains — and Ootoya does not itself state what the absence of an icon means. We read a missing icon as meaning the allergen is not used as an ingredient in that dish, because the document declares its scope ("under Japan's Food Sanitation Act, allergen labelling covers 28 items") and because its per-dish listings were measured to be exhaustive. This is our own reading, and it is no guarantee against cross-contact: Ootoya itself states that allergens can be introduced unintentionally during cooking and that kitchen utensils, tableware, noodle-boiling equipment and frying oil are shared. Show the originalこの一覧に品目ごとの欄はなく、含まれるアレルゲンのアイコンが並ぶ形式で、アイコンが無い状態の意味を大戸屋自身は明文化していません。当サイトでは、資料が「食物アレルギーの表示は、食品衛生法に基づき28品目を対象としています」と対象範囲を宣言していること、および商品ごとの列挙が実測で網羅的であることから、アイコンの無い品目をその商品の原材料としては使用していないと読んで掲載しています。これは当サイトの読み取りであり、混入がないことの保証ではありません。大戸屋自身も、厨房内で意図せずアレルギー物質が混入する場合があること、厨房器具・食器・茹で麺機・揚げ油を共有していることを明記しています。 |
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
Each restaurant publishes its own allergen table, covering the 28 items specified under Japan's Food Sanitation Act. The table marks the allergens a dish contains with icons; where no icon is shown, we list the allergen as not used as an ingredient in that dish, which is our own reading of the table. Set meal (teishoku) listings reflect an order with white rice; switching to five-grain rice adds sesame. Ootoya states that it does not accept requests to change cooking methods on account of an allergy, or to change specific ingredients, seasonings or the like. Kitchen utensils, tableware, noodle-boiling equipment and frying oil are shared, so unintended cross-contact with allergens not shown for a dish is possible. Ootoya advises that anyone who is sensitive should consult a doctor and decide for themselves.
