Franchise
All 9 allergens Japan requires can be checked in the official document. Plus 19 recommended items, excluding Pistachio. (Eggs, Milk, Wheat, Buckwheat, Peanuts, Shrimp, Crab, Walnut, Cashew Nuts) We confirmed in August 2026 that this is the current document.
This page is an entry point we compiled from officially published information. Always make your final check against the official source.
Covers 28 items (pistachio not covered), this document covers part of the menu and points elsewhere for the rest
What is stated about severe allergies
Ichiran says it takes great care during manufacturing and preparation to avoid contact with other allergens, but states that it cannot guarantee this. Because sensitivity to allergens varies from person to person and even a trace amount of contamination can trigger a reaction, it advises anyone who is concerned to consult their own doctor before ordering and to make the final decision themselves about whether to eat.(machine translation)

製造・調理の際には他のアレルギー物質と接触しないよう細心の注意を払っているものの、それを保証するものではないとしています。アレルギー物質への感受性には個人差があり、微量の混入でも症状が出る場合があるため、心配な場合は購入前に専門医に相談したうえで、ご自身で食べるかどうかを判断するよう案内しています。

Some ramen variants (such as the Classic Tonkotsu Ramen served since the restaurant's founding, Gokaku Ramen and Ra-Mugi Noodles, the Kamadare Tonkotsu Ramen, and the 100% Tonkotsu-Free Ramen) are said to be served only at certain locations.(machine translation)

- Notes for reading
This table covers only the ramen menu; allergy information for souvenir products is on a separate page. The items covered are the 8 legally mandatory allergens plus 20 additional recommended items, 28 in total. A filled dot (●) means the item is included as an ingredient. An × mark means the item is not used as an ingredient -- this site's own reading from how the table is built (the cell actually contains an × character, not a blank space), since the document's own legend text does not define this mark. The triangle (△) is used on the seaweed (nori) row: the note explains that the seaweed is harvested from waters where shrimp, crab, abalone, squid, salmon, and mackerel live, so trace contamination from those six species is possible -- but in the actual table, △ appears only on the crab and abalone columns of that row. On that same nori row, besides the remaining four of those six species (shrimp, squid, salmon, mackerel), the '※1' shared-facility mark also appears on columns the note does not name at all -- wheat, milk, egg, beef, soy, chicken, pork, gelatin, and sesame -- so the nori row's contamination caution reaches well beyond the six species the note mentions. The mark ※1 means the item itself is not used as an ingredient, but the dish is manufactured in the same location as other company products that do contain it, so trace contamination is possible.

この表はラーメンメニューのみが対象で、おみやげ商品のアレルギー情報は別ページに掲載されています。対象品目は特定原材料8品目と、その他の推奨品目20品目を合わせた28品目です。●はその品目を原材料として含むことを示します。×はその品目を使用していないことを示す記号として当サイトが表の作りから判断したもので(無地の空欄ではなく、実際に×の記号が入ります)、資料の凡例文自体はこの記号の意味を明記していません。△は海苔(のり)の行に使われる記号で、注記文にはえび・かに・あわび・いか・さけ・さばが生息する海域で採取した海苔を使用しているためこれらのアレルゲンが微量混入する可能性があるとありますが、実際の表でこの注記どおり△が付くのは「かに」と「あわび」の列だけです。同じのりの行では、注記が名指しする残り4品目(えび・いか・さけ・さば)に加えて、注記に含まれない小麦・乳・卵・牛肉・大豆・鶏肉・豚肉・ゼラチン・ごまの列も※1(工場での混入)扱いになっており、のりの混入注意は注記文が名指しする6品目より広い範囲に及びます。※1はその品目自体は原材料として使用していないものの、他の同社商品と同じ場所で製造しているため混入する可能性があることを示します。

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 | Cross-contact scope |
|---|---|---|
| ● | Contains this item as an ingredient.Show the originalその品目を原材料として含みます。 | The scope of possible cross-contact is not specified |
| △ | The seaweed (nori) used is harvested from waters where shrimp, crab, abalone, squid, salmon, and mackerel live, so these allergens may be present as trace contamination. Show the original使用している海苔(のり)は、えび・かに・あわび・いか・さけ・さばが生息する海域で採取されており、これらのアレルゲンが微量混入する可能性があります。 | The scope of possible cross-contact is not specified |

| × | The document's own legend text does not define what this mark means. Having checked every cell in the table, we found that it appears in every cell for an item that carries none of the defined marks (● = contains, △, ※1). This site reads it, from the structure of the table, as meaning the item is not used as an ingredient -- that reading is our own judgement, not a statement the document itself makes, and it is not a guarantee against contamination. Show the originalこの記号の意味は資料自身の凡例文には明記されていません。表の全セルを確認したところ、●(含む)・△・※1のいずれの記号も付いていない品目には必ずこの記号が入っていることを確認しました。当サイトはこれを表の作りから「原材料として使用していない」ことを示す記号と判断していますが、これは資料自身の説明ではなく当サイトの読み取りであり、混入がないことを保証するものではありません。 | The scope of possible cross-contact is not specified |

Allergy notes
Ichiran publishes an allergy information chart for its ramen menu on its official site, based on Japan's 8 legally mandated allergen items. While the chain says it takes care during manufacturing and preparation, it states that trace amounts of other allergens may still get mixed in, and advises anyone concerned to consult a doctor before ordering and make the final decision themselves. Allergens not listed in the chart can be confirmed through the inquiry contact. Allergy information for souvenir products is on a separate page.
