ロイヤルホストRoyal Host

Franchise

All 9 allergens Japan requires are listed menu by menu. Only 20 of the 20 recommended items can be checked. (Eggs, Milk, Wheat, Buckwheat, Peanuts, Shrimp, Crab, Walnut, Cashew Nuts) We checked the material on the official site in October 2026; it may have changed since.

This page is an entry point we compiled from officially published information. Always make your final check against the official source.

Allergen

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

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.

Notes for reading

Condiments added freely at the table (ketchup, mustard, Tabasco, soy sauce, sauce, stick sugar, gum syrup, coffee creamer, etc.) are outside the scope of this table. "French mustard," however, is listed as its own menu item rather than a table condiment, and carries its own allergen information. The table has columns for the 29 items it calls "foods containing allergenic substances (allergens)" (アレルギー物質(アレルゲン)を含む食品29品目), and there is no column for matsutake mushroom.

Show the original

卓上でお好みで使う調味料(ケチャップ、マスタード、タバスコ、しょうゆ、ソース、スティックシュガー、ガムシロップ、コーヒーフレッシュなど)はこの表の対象外です。ただし「フレンチマスタード」は卓上調味料ではなく単品メニューとして表に含まれており、独自のアレルゲン情報を持ちます。また、表は「アレルギー物質(アレルゲン)を含む食品29品目」の列を持ち、まつたけの列はありません。

How it appearsMeaningCross-contact scope
●
Contains this allergen (one of the 29 labeled items) as an ingredient.

The scope of possible cross-contact is not specified
△
The chain says it uses this mark, based on information from the manufacturer, for items with contamination. It defines contamination as the unintended mixing of a very small amount of an allergen that is not used as an ingredient, for example when the manufacturer's factory or production line also makes foods containing that allergen.
Show the original資料は、製造元から得た情報に基づいて、コンタミネーション(原材料としては使っていないが、製造の際に意図せず混入すること。例として、製造元の工場内や製造ラインで該当するアレルゲンを含む食品も製造している場合)があるものに付けた印としています。
Handled on the same factory line
調査中
The document explains this mark only as "調査中 ⇒ allergen under investigation". This site treats it as the allergen's status being under investigation at the time of the document, and does not read it as not used.
Show the original資料は、この記号の意味を「調査中⇒調査中アレルギー」とだけ示しています。当サイトは、その品目の使用状況が資料の時点で調査中であるものとして扱い、使っていないとは読みません。
The scope of possible cross-contact is not specified
- (our reading)The document itself does not define this dash mark. The table is a matrix with one column per allergen (29 items), the "present" marks (●, △, 調査中) are all defined in the legend, and we confirmed only those marks and this dash occur in the cells. We therefore read the dash as "not used as an ingredient" as our own editorial judgement from the table's structure — the document does not say so itself, and this is not a guarantee against unintended cross-contact.
Show the originalこの記号(-)自体は資料内で定義されていません。表は29品目それぞれに列を持つマトリクス形式で、陽性側の記号(●・△・調査中)はすべて凡例で定義されており、出現するのはこれらの記号と「-」のみであることを確認しています。そのため「-」は「原材料として使用していない」と当サイトの判断で読み取っていますが、これは資料自身の宣言ではなく、混入がないことを保証するものでもありません。
The scope of possible cross-contact is not specified

Allergy notes

Royal Host's official allergen table marks foods that contain an allergen with a ● symbol, and possible cross-contact from the manufacturer with a △ symbol. Stores share cooking equipment, tableware and frying oil, so please be aware that unintended allergen cross-contact may occur.

Show the original

公式サイトのメニュー表で、アレルギー物質を含む食品を●印、製造元由来の混入の可能性を△印で表示しています。店舗では調理器具・食器・揚げ油を共用しているため、意図しないアレルゲンの混入にご注意ください。

Allergy-friendly menu

The allergen table has a section headed "low-allergen menu" (curry rice, bread, gateau chocolat and others). Some items in this section also carry a ● or △ mark, so please check each item in the table.

Show the original

メニュー表には「低アレルゲンメニュー」の区画があります(カレーライス・パン・ガトーショコラ等)。この区画の品目にも●印や△印が付いているものがあるため、品目ごとに表でご確認ください。
