Seafood /Shellfish: Other standard toppings in Sushi include Shrimp, octopus, crab, and more.

Soy: Can be avoided to an extent. Soy sauce is a common dipping sauce for sushi. Additionally, it may be added as a glaze or marinade for some preparations. It’s best to find dishes with no sauce on them, and avoid dipping your sushi in soy sauce.

Eggs: While not commonly an allergen in Sushi, there is a variation of sushi that uses a Japanese omelette (typically contains dashi) instead of fish. If you are allergic to fish or eggs, then avoid Tamagoyaki Sushi.

Food FAQs

How do I say I have an Allergy?

To say that you have a food allergy, say the following. 

私は食べ物アレルギーがあります。

(Wa-ta-shi wa ta-be-mo-no a-re-ru-gi ga ari-mas.)

[Allergen] は食べません。

[Allergen] wa tabemasen

How do I say my Allergen in Japanese?

Common Allergens

  • Soy (大豆, dai-zu)
  • Wheat (小麦, ko-mu-gi)
  • Egg (卵, ta-ma-go)
  • Milk/Dairy (乳, nyū)
  • Fish (魚, sa-ka-na)
  • Shellfish (甲殻類, kō-ka-ku-rui)
  • Seafood (シーフード, shi-fu-do)
  • Buckwheat (そば, soba)
  • Sesame (ごま, goma)
  • Peanuts (落花生, rakkasei)
  • Tree nuts (ナッツ, nattsu)
Is it OK to ask for an allergen to be removed.

Yes, it is for allergy purposes, but the request may not be able to be accommodated all the time. Typically, restaurants in Japan have issues with substitutions for preferences, not allergies. Here are some helpful tips:

 

Be direct and upfront about the allergy. 

In Japan, “preferences” (like disliking a taste) are often seen differently from allergies. If it’s a true allergy, make that very clear. Tell the staff that you have an allergy, and don’t be afraid to use Google Translate to assist with the ordering process.

 

Broths and marinades are not usually possible.

Broths and marinades are usually prepared well before the restaurant opens. As such, there is limited flexibility in what can be done in this space.  Toppings like sauce drizzles, garnishes, etc., are more than likely to be accommodated.

Chain restaurants vs. small shops. Larger chains (like ramen shops, curry houses, and fast food) often publish allergen charts and can be safer for substitutions. Small mom-and-pop places may not be flexible because their recipes are fixed.

 

I'm having an allergic reaction, how do I get help?

Alert the restaurant staff right away and ask for them to call the emergency services for you. 

If you are alone, then dial 119, or find the nearest hospital. 

We highly recommend getting travel insurance that covers allergic reactions if you are at risk of an allergic reaction
