Fujiichiban Allergy Information (dish-by-dish chart, a single image) — Covers the mandatory items only (how many depends on the chart's edition) (8 columns confirmed) — as of Apr 1, 2025

This document is image-only, so in-page search and screen readers will not work on it. Expect to zoom in.

Document size

A single tall image holding one chart. Ramen, rice dishes, gyoza and fried dishes, desserts and drinks, and toppings and small plates all run through the same table without section headings.

How to use it

Look for the dish name going down the chart. The table breaks into two blocks, and the lower block has no header row of its own, so its columns are read in the same order as the header above it: egg, milk, wheat, shrimp, crab, walnut, buckwheat, peanut, from the left.

上から商品名を探して読みます。表は途中で2つのまとまりに分かれていますが、下側のまとまりには品目名の見出し行がないため、上側の見出し(左から 卵・乳・小麦・えび・かに・くるみ・そば・落花生)と同じ並びで読みます。

Notes for reading

The chart covers only Japan's 8 mandatory allergens (egg, milk, wheat, shrimp, crab, walnut, buckwheat and peanut); no other allergen has a column. There is also no column for cashew nut, which became a mandatory item in April 2026. The chart does not explain what its marks or blanks mean, but every allergen it covers has its own column and each cell holds either the one mark or nothing at all. From that structure this site reads an unmarked cell as meaning the allergen is not used as an ingredient. That is our judgement, not something the document states, and it is no guarantee against unintended trace cross-contact. The chain states that allergens not originally part of a dish may unintentionally adhere to it or get mixed in during preparation at the restaurant. It also states that some products, such as limited menu items, may not appear on the chart. The row for the french fries covers them without the ketchup and mayonnaise served alongside. The rows for the gyoza set and the Fujiichi set note that the shiso and ginger versions of the same item have the same contents. Desserts, drinks and toppings are not on a separate chart — they sit in this same table.

対象は特定原材料の8品目(卵・乳・小麦・えび・かに・くるみ・そば・落花生)だけで、それ以外のアレルギー物質には欄がありません。2026年4月から表示義務に加わったカシューナッツの欄もありません。この一覧表は印や空欄の意味を説明していませんが、対象の品目それぞれに専用の列があり、各欄には同一の印か空欄しかありません。当サイトはこの構造から、印のない欄をその品目を「原材料として使用していない」ものとして読み取っています。これは当サイトの判断であり、資料自身がそう述べているわけではなく、意図しない微量混入がないことを保証するものでもありません。本来そのメニューに含まれていない他のアレルギー物質が、店舗での調理時に意図せず付着・混入する場合があるとされています。限定メニューなど、一覧表に載っていない商品がある場合があります。「ポテトフライ」の行は、添えられるケチャップ・マヨネーズを除いた状態についての記載です。「餃子セット」「フジイチセット」の行には、青じそ・しょうがを使った同種の商品も同じ内容である旨が添えられています。デザート・ドリンクやトッピング類は別の表ではなく、同じ一覧表の中に並んでいます。

Legibility notes

The chart is published as an image, so its text cannot be selected or searched. It is very tall and needs to be zoomed in on, but it is a ruled table and the characters themselves are legible.

How it appearsMeaning
This chart never explains what its marks mean. We read a marked cell as containing that allergen; the document itself does not state this.
Show the originalこの一覧表は記号の意味を説明していません。当サイトでは、印の付いた欄をその品目を含む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ありません。
(空欄)
The chart does not state what a blank cell means, but every allergen it covers has its own column and each cell holds either the one mark or nothing at all. This site reads a blank as "not used as an ingredient" from that structure -- our own judgement, not a guarantee against unintended trace cross-contact. The document itself notes that allergens not originally in a dish may adhere or be mixed in during preparation at the store. It also states that it covers Japan's 8 mandatory allergens. It has no column for cashew nut, which became a mandatory item in April 2026.
