Reading Allergen Charts and Stating Food Allergies in Japanese

What this guide can and cannot do for you

Everything below is language help. It teaches you to recognise words on a packet and to ask a clear question in a shop or a restaurant. It cannot tell you whether a particular dish is safe, because that depends on the kitchen, the supplier and the day. Labelling requirements in Japan have been revised more than once and will change again, so treat any list of allergens, including the one here, as a starting point to check rather than as the current legal position.

If your allergy is serious, three things matter more than vocabulary: a written card in Japanese naming your allergens and what happens if you eat them, medical advice about what to carry and what to do in a reaction, and the habit of confirming with staff every time rather than assuming. Ask, wait for the answer, and change your order if the answer is vague. A dish you skip costs you nothing.

The allergen words you will meet

Notice that labels often use the short written form rather than the everyday spoken one. A packet says 乳 where you would say ミルク or 牛乳 in conversation, and it may write えび and かに in hiragana even though the words also have kanji. Some items on this table are in the mandatory group and some in the recommended group, and that division has changed over time, so read what is printed rather than assuming a category.

The two ways a label shows an allergen

Japanese packaging generally uses one of two formats, and once you know which one you are looking at, reading it takes seconds. The first is the itemised style: each ingredient that contains an allergen carries it in brackets straight after the ingredient name, so マヨネーズ（卵を含む） tells you the mayonnaise contains egg. The second is the summary style: the ingredient list runs normally, and a single bracket at the very end collects every allergen in the product.

The summary line is the one to look for first, because it is a single place that names everything. It usually begins with 一部に and ends with を含む, with the allergens listed between them separated by dots. Below that you may find a separate sentence about the factory, which is not part of the ingredient list at all: it warns that other allergens are handled on the same equipment. That sentence is a risk statement, not a declaration that the product contains the ingredient.

Ingredients that hide where you do not expect them

Several very common Japanese ingredients carry allergens that are invisible in the dish's name. Ordinary soy sauce is usually made with wheat as well as soya. Many soups, sauces and simmered dishes are built on だし, and that stock is frequently made with dried bonito or dried sardine, which makes a plain-looking vegetable dish a fish dish. 魚介エキス, a seafood extract, turns up in dressings and instant soups, and gelatine appears in desserts that look purely dairy.

This is why the useful question is rarely just about the headline ingredient. Asking whether a vegetable dish contains fish sounds strange until you know about dashi, and it is exactly the question that finds the problem.

Reading a restaurant allergen chart

Chain restaurants often publish a grid: dishes down the left, allergens across the top, and a mark in each cell. The chart usually has a legend, 凡例 (hanrei), explaining what the marks mean, and you should read it rather than guess, because the symbols are not standard between companies. A filled circle commonly means the allergen is used, a triangle commonly means it may be present through shared equipment, and a blank or a dash commonly means not used.

Charts also carry a footnote that matters as much as the grid. It usually says that ingredients and suppliers change, that the same kitchen handles other allergens, and that the restaurant cannot guarantee the absence of a substance. Take that footnote seriously rather than treating the grid as a promise, and ask staff to confirm anything you are relying on.

Saying your allergy so it is taken seriously

Say it at the start, before you order, and say it flatly. Learners often soften the sentence so much that it sounds like a preference, and a preference gets a polite nod rather than a trip to the kitchen. Two short sentences do the work: the allergy, then the consequence. Adding 命に関わります or 救急車を呼ぶことになります is not dramatic in Japanese; it is the phrase that moves the request from taste to safety.

Asking whether a dish contains something

Three question patterns cover almost everything. 入っていますか asks whether the ingredient is in the dish, 使っていますか asks whether the kitchen uses it, and 何が入っていますか asks openly what is in something. Use the ingredient plus は rather than が in these questions, because you are asking about that one item against a background of everything else.

わかりかねます is a genuinely useful answer, not a brush-off: it means the person does not know and is not going to guess. Treat it as a no, thank them, and order something else.

Asking for an ingredient to be left out

Requests to remove something work best when they are specific and small. 抜き attached to the ingredient is the standard restaurant word, and it is what staff themselves use when they relay the order to the kitchen. If the answer is that it cannot be done, accept it immediately; pushing rarely produces a safer plate, only a reluctant one.

Shared pans, shared oil, shared boards

For a serious allergy the ingredient list is only half the question. Fried items often share a fryer, noodles often share boiling water, and one pair of tongs may serve several trays. Buckwheat and wheat noodles cooked in the same pot is a well-known example, and shared frying oil is another. Ask these questions calmly and in order, and accept the answer you get, including an uncertain one.

Vegetarian, vegan and halal requests

These are not allergy requests, and it is worth being honest about that. Vegetarian and vegan eating is far more common in Japan than it used to be, but it is still less routinely catered for than a stated allergy, and the language around it is looser. Many staff understand ベジタリアン as no meat rather than no animal products, so name the specific things you avoid rather than relying on the label alone.

The recurring problem is stock and fat. A vegetable dish is often simmered in fish stock, miso soup usually has a fish base, and fried food may be cooked in oil that has handled pork. For halal eating, pork-derived ingredients and cooking alcohol appear widely, including in sauces and marinades, and certified options exist mainly in specific restaurants. Asking about だし and 豚肉 by name does more work than any single label word.

Your card, the pharmacy and an emergency

Carry the allergy in writing. A card that names your allergens in Japanese, states the severity in one line and says what to do in a reaction removes every problem of pronunciation and every misheard word. Hand it over rather than reciting it when the restaurant is loud. Keep a photograph of it on your phone as well, and follow your doctor's instructions about what else you carry.

Rehearse the last three lines until they come out without thinking, because that is the moment when your Japanese will be worst. This blog's guide to Japanese at the doctor covers what happens after the ambulance arrives; what matters here is being able to say the first sentence clearly. And once again: this is language practice, not medical advice, and a serious allergy needs a doctor's plan behind it.
