Halal terms

What is mirin, and why does it matter?

You ordered a pork-free dish in Japan and then heard the sauce may contain mirin.

Mirin is a sweet seasoning used in Japanese cooking. It contains alcohol. If you avoid alcohol in food, it is one of the first ingredients to ask about in Japan.

How will I meet it on the trip?

Japan’s tourism board warns that cooking sake and mirin are used widely in Japanese cooking, and that some miso contains alcohol unless it is labelled additive-free (mu-ten-ka)¹. It may not be named on the menu, so you will not see it unless you ask.

Which dishes should I ask about?

Glazed or grilled dishes with a sweet sauce
Simmered dishes and noodle soup broths
Dipping sauces and marinades
Any set meal where the sauce is not described

A sentence to send

“Do you use mirin or cooking sake in this dish, the sauce or the broth?” Show it on your phone, or add it to a message when you book. The dietary enquiry brief generator helps you write the full set of questions.

If the answer is vague, treat the dish as unknown, which is never the same as halal. Our claim states guide explains why. To compare tour lunches by what the operator can confirm, use the meal-assurance comparison tool.

Sake, pork-free and halal certificate are explained in the halal terms hub.

If your Japan route includes set meals or tour lunches, send us the days and we will help you write the sauce and alcohol questions for each one.

Common questions

Is mirin the same as sake?

No, though both are rice-based alcohol used in Japanese cooking. Mirin is a sweet seasoning added to sauces and glazes, while sake is a drink that is also used to cook. A kitchen may use one, the other or both, so ask about each by name.

Does the alcohol cook away?

That is a question for your ustaz or your state mufti office, because views differ and this glossary gives no ruling. What you can do is decide your own line before the trip, then ask the kitchen whether mirin or cooking sake is in the dish.

Can a pork-free or vegetarian dish still contain mirin?

Yes. A dish with no meat can still be seasoned with mirin or finished with a glaze that contains it. That is why pork-free or vegetarian is not an answer to the alcohol question. Ask about the sauce, broth and any glaze separately.
