Why this guide matters
If you have food allergies in Japan, you can eat well and stay safe—with the right system. Packaging often looks different, ingredient lists are in Japanese, and restaurant menus may rely on soup stocks or sauces that hide allergens. Here, you’ll learn how to decode labels, speak with staff, and use government tools that make communication easier.

How food allergen labeling works in Japan
Japan’s Food Labeling Act sets national standards for what must appear on packaged food labels. Enforcement and details flow through the Food Labeling Standards managed by the Consumer Affairs Agency (CAA). In short:
- Prepackaged foods must show ingredients in Japanese and disclose specific allergens.
- Japan defines 8 “specified” allergens that must be labeled: wheat, buckwheat, egg, milk, peanut, shrimp, crab, and walnut.
- An additional group of “recommended” allergens (20 items such as soy and sesame) are also commonly listed.
- Labels are designed primarily to protect people with allergies—so they highlight allergens rather than broader terms like “gluten” as a concept.
Why this matters: If you’re allergic to wheat, the allergen declaration is very helpful. But if you avoid gluten for medical reasons (celiac disease), note that barley or rye may not be captured by the wheat allergen line—so you still need to read the full ingredient list.
For the legal backbone, see the English translation of the Food Labeling Act, which unifies Japan’s labeling framework.

Not just the label: what restaurants must tell you
Japan’s packaged-food rules are strict, but restaurants and fresh-food counters follow different expectations. Tokyo’s official guidance notes there is no obligation to label allergens for foods sold loose or served in eateries. Instead, the focus is on informing customers on request and preventing incidents—with tools like allergen charts, training, and communication sheets. This is why polite, clear questions matter so much when dining out.
To make that easier, both Japan’s CAA and the Tokyo Metropolitan Government publish Food Allergy Communication Sheets you can show on your phone. They include Japanese/English wording so staff can quickly understand what you must avoid. Download them before you go.
Step-by-step: how to read a Japanese food label
Use this routine in supermarkets and convenience stores:
- Scan the allergen line first. If your allergen is one of the eight specified, it should be clearly disclosed. (Examples: 小麦 for wheat, 卵 for egg.)
- Check the full ingredient list. Look for non-specified ingredients that still matter to you (e.g., barley 大麦, rye ライ麦, gelatin ゼラチン, sesame ごま).
- Look for “manufactured in a facility with…” statements. Japan’s phrasing varies, but many packages note shared lines or kitchens—useful if you must avoid cross-contact.
- Confirm sauces and stocks. Seasonings like soy sauce, miso, curry roux, or soup bases can hide allergens such as wheat, sesame, milk, or fish extracts.
- When in doubt, ask staff. Supermarket staff can check a product’s allergen sheet or show the ingredient label up close.

Restaurant scripts that work
You don’t need perfect grammar. Short, polite sentences help staff help you.
- “I have a severe allergy to [allergen]. Could you check the ingredients?”
重いアレルギーがあります。[アレルゲン]が入っていないか確認していただけますか? - “Does this use soup stock with fish or meat?”
この料理は魚や肉のだしを使っていますか? - “Could you prepare it without [item]?”
[食材]抜きで作っていただけますか? - “Is there any wheat?”
小麦は入っていますか?
If communication stalls, open an official allergy card on your phone and point to your allergens. The CAA and Tokyo Food Safety sheets are designed for exactly this situation.

Table: common “watch-outs” in Japanese cooking
| Dish or ingredient | Why it’s tricky | What to ask or order instead |
|---|---|---|
| Miso soup | Often uses bonito/fish dashi, not vegan | Ask for kombu/shiitake dashi miso or skip soup |
| Ramen | Broth and tare may contain soy, sesame, milk, shellfish | Ask about broth base and toppings; choose simple shio with confirmed ingredients |
| Curry roux | Ready-made blocks can include wheat, milk, soy | Ask for allergen info; consider spice-based curries |
| Fried items | Shared fryers and batters (wheat, egg, milk) | Choose grilled/steamed dishes; confirm oil use |
| Dressings and sauces | Sesame, soy, milk, or wheat in soy sauce | Request oil + vinegar or salt + lemon |
| Sweets and jellies | Gelatin (often pork-derived) or milk | Choose kanten/agar desserts and dairy-free options |

Gluten, wheat, and Japan’s labels
If you must avoid gluten, remember: Japan’s allergen system is centered on allergens (e.g., wheat), not on a legal definition of “gluten-free.” In practice, the phrase “gluten-free” is not regulated by a national threshold the way it is in countries like the U.S. and Canada. That is why you should read every ingredient list and look for recognized third-party gluten-free certifications when possible.
For context, compare with the U.S. FDA’s 20 ppm gluten-free rule—useful to understand why products in Japan might use “wheat-free” language but still contain barley or rye. (This is a comparison to underscore the difference—not a Japanese rule.)

How to use allergy communication sheets
Before you eat out, download one of these free, bilingual tools:
- CAA Food Allergy Communication Sheet: succinct, smartphone-friendly, and recognized nationwide. You can circle your allergens and show it to staff.
- Tokyo Food Safety “Allergy Communication Sheet”: from the Tokyo Metropolitan Government; designed for customer–restaurant conversations.
Tips for using the sheet effectively:
- Add your name, phone number, and the specific condition (e.g., anaphylaxis).
- Circle your allergens and cross out anything that absolutely cannot be in your food.
- Politely ask the staff to check with the kitchen and to suggest alternative dishes.
- If the restaurant says it cannot guarantee safety, choose another place. Your health comes first.

Sample allergy cards you can copy
If you prefer a customized card, consider reputable templates tailored for Japan (laminated or digital). These can complement, not replace, the official sheets. Look for cards that:
- Use clear Japanese,
- Explain your severity,
- List hidden sources of your allergen (e.g., dashi for fish/shellfish),
- Ask for separate utensils to reduce cross-contact.
You can also make your own based on official phrasing, or purchase pre-written Japanese allergy cards from specialized providers.
Supermarkets and convenience stores
Japan’s major chains publish online allergen information for many ready-to-eat items, and in-store labels are consistent with national rules. Still, recipes change and local selections vary. Always re-check labels, especially for seasonal products or limited editions.
Good habits for shopping days:
- Buy plain staples (rice, tofu, fresh vegetables, plain fish/meat) and add your own verified sauces.
- Favor short ingredient lists when trying something new.
- Keep a translation app ready for unfamiliar kanji.

Table: what allergen names can look like on labels
| Allergen you’re avoiding | Words that may appear | Where you might see them |
|---|---|---|
| Milk | 乳, 乳成分, バター, クリーム, チーズ, ホエイ | Breads, sweets, roux, dressings |
| Egg | 卵, たまご, マヨネーズ | Mayo-based salads, batters, breads |
| Soy | 大豆, 醤油, みそ, 豆乳 | Tofu, sauces, soups, snacks |
| Fish | 魚, かつおだし, いわし, さば | Stocks, sauces, furikake |
| Shellfish | えび, かに, ほたて | Ramen oils, sauces, mixed fritters |

| Peanut | ピーナッツ, 落花生 | Snacks, baked goods |
(Always confirm the allergen line; ingredient phrasing varies.)
Eating outside of Tokyo
Large cities have better bilingual signage and more allergy-aware restaurants. Smaller towns can be friendly too—but you’ll rely more on the communication sheet and simple orders (grilled or steamed dishes). When traveling, save venue allergen pages and call ahead if you’re planning a special meal.

Cross-contact and shared equipment
Even when an allergen isn’t an ingredient, it can appear through shared fryers, grills, knives, or cutting boards. Japan’s official materials encourage restaurants to train staff, share allergen information, and prevent incidents, but each kitchen is different. If cross-contact is a serious risk for you, communicate that clearly and ask whether a separate pan or area is possible. Tokyo’s food safety guidance emphasizes proactive information-sharing to prevent incidents in eateries.
Build your personal “safe order” list
Create a short list of go-to items you can order (or assemble) almost anywhere:
- Salt-grilled fish or chicken with plain rice and a side of simple vegetables.
- Hiyayakko (chilled tofu) with toppings removed or replaced if needed.
- Onigiri with plain salt, seaweed, or umeboshi—read labels carefully for mayo, bonito, or soy sauce.
- Salads dressed with oil and vinegar or just salt and lemon.
- Miso soup only when you confirm the stock is safe for your allergy.
- Fruit and plain yogurt (if dairy is not an issue) for quick breakfasts.

Troubleshooting: what if staff seem unsure?
- Slow down and simplify. Point to the allergen on your card and say, これが食べられません (“I cannot eat this”).
- Ask for a manager or kitchen check. 店長かキッチンに確認していただけますか?
- Offer a safe alternative. “Grilled with salt only, please” (塩だけで焼いてください).
- If the answer is still unclear, leave kindly. There are many options nearby; your safety matters most.
Staying current as rules evolve
Japan’s Food Labeling Standards are updated over time. For example, 2024 updates adjusted certain additive and allergen label wording and the list of “recommended” items. Keep an eye on the CAA’s English portal for official pamphlets, allergen PDFs, and notices about revisions. We also track expert newsletters that summarize changes in plain English.
Frequently asked questions
Do restaurants have to label allergens on menus?
Not generally. Packaged food allergen rules don’t automatically apply to food sold loose or served in eateries. Tokyo’s guidance centers on providing information and preventing incidents, not mandatory allergen menu labels. Always ask, and use a communication sheet.
Where can I get an official allergy card in Japanese?
Download the CAA Food Allergy Communication Sheet or Tokyo’s Allergy Communication Sheet. Circle your allergens and show it to staff. These are free and bilingual.
Is “gluten-free” a regulated claim in Japan?
Japan’s system focuses on allergen disclosure (e.g., wheat) rather than a uniform national gluten-free threshold. Treat “gluten-free” wording carefully and read ingredients, especially for barley or rye. Compare with the U.S. FDA’s 20 ppm standard to understand the difference.
I have multiple severe allergies. What’s the safest approach?
Cook more at home, carry your allergy card, favor restaurants with allergen charts, and stick to simple preparations. If you need emergency care, call 119 and show your allergy list to responders. See Emergency Numbers and Expat Support Centers and International Patient Services.
