- Notes for reading
The table covers 27 items: the 8 mandatory allergens under Japan's food labeling law plus 19 additional recommended items. Macadamia nut is still being prepared for disclosure and cannot be judged from this table. In-store cooking equipment, dishware, and food storage areas are shared, and every dish is cooked in the same kitchen and washed in the same sink, so even an item with no mark cannot rule out unintentional trace cross-contact during cooking. In addition, some items have store-specific variants, so a dish with the same name may have different ingredients and allergen content depending on the location.

対象は食品表示法の義務8品目と表示推奨19品目を合わせた27品目です。マカダミアナッツについては対応の準備中で、この表では判断できません。店舗では調理器具・食器・食材の保管場所を共有し、すべての料理を同じ調理場で調理・同じシンクで食器を洗浄しているため、印のない品目についても調理中に意図しない微量混入が起こる可能性は否定できません。また、一部の品目には店舗独自のバリエーションがあり、同じ名前の料理でも店舗によって成分やアレルゲンの内容が異なる場合があります。

Allergy notes
Zundouya publishes an allergen table covering 27 items — the 8 items Japan's food labeling law requires plus 19 additional recommended items — for nearly the whole menu (ramen, rice dishes, toppings, drinks, and more), marking each item as either used as an ingredient or as something that may come into contact with other ingredients during the raw ingredient's own manufacturing process. Macadamia nut is still being prepared for disclosure and cannot be judged from this table yet. In-store cooking equipment, dishware, and food storage areas are shared, and every dish is cooked in the same kitchen and washed in the same sink, so even an item with no mark cannot rule out unintentional trace cross-contact during cooking. Some items are offered as store-specific variants, so a dish with the same name may have different ingredients and allergen content depending on the location. Sensitivity to allergens varies by person, so the chain asks customers to make their own final decision and consult a doctor if concerned.

アレルゲン情報(食品表示法の義務8品目+推奨19品目=27品目)を、原材料として使用しているか・原材料の製造工程で他の原材料との接触や混入が生じ得るかの2段階で、ラーメン・ご飯物・トッピング・ドリンクなどほぼ全メニューについて公開しています。マカダミアナッツは対応準備中のため、この表では判断できません。店舗では調理器具・食器・食材の保管場所を共有し、すべての料理を同じ調理場で調理・同じシンクで食器を洗浄しているため、印のない品目についても調理中に意図しない微量混入が起こる可能性は否定できません。一部の品目は店舗独自のバリエーションとして提供されており、同じ名前の料理でも店舗によって成分やアレルゲンの内容が異なる場合があります。アレルギー物質への感受性には個人差があるため、最終的な判断はご自身で行い、心配な場合は専門医に相談するよう案内されています。
