Is Dashi Vegetarian? Mostly No — But Vegan Dashi Is Delicious

Good news for vegetarians visiting Japan
you can enjoy dashi —
once you know what to look for.
The traditional version usually contains katsuobushi (dried bonito flakes), so it isn't vegetarian.
But kombu (kelp) and dried shiitake make a rich, 100% plant-based dashi that's every bit as delicious — and it's the base of every dish in our vegan cooking class.
(We also run a 100% plant-based cooking class in Arashiyama where every ingredient is explained — but more on that at the end.)
🌱 1. Why Traditional Dashi is Not Vegetarian
Dashi is Japan's fundamental cooking base.
Traditional dashi is usually made from:
・Katsuobushi (dried bonito flakes → fish)
・Niboshi (dried sardines)
・Kombu (seaweed)
・Shiitake mushrooms
While kombu/shiitake versions exist, most restaurants use fish-based dashi, even in dishes that appear vegan.
Dashi
・Miso soup
・Ramen broth
・Udon and soba soup
・Simmered vegetables
・Curry roux
・Tempura dipping sauce
・Rice seasonings
・Pickles
If you don't ask, it almost always contains fish.
⚠️ 2. Common Japanese Dishes That Contain Dashi
Travelers often think these foods are safe—but they usually aren't:
❌ Miso soup
→ Almost always made with fish-based stock.
❌ Tempura dipping sauce (tentsuyu)
→ Always contains bonito-based dashi.
❌ Udon/soba broth
→ Fish-based 100%.
❌ Pickles
→ Often seasoned with dashi or fish-based seasonings.
❌ Japanese curry
→ Many curry roux blocks contain beef or pork extract.
❌ Simmered vegetables
→ Frequently cooked in bonito broth.
❌ Onigiri
→ Some fillings include fish, bonito flakes, or mayo.
👉 Rule: If it's Japanese and liquid-based, assume dashi is included unless proven otherwise.
🥢 3. How to Ask About Dashi in Japanese (Life-Saving Phrases)
Screenshot these phrases and show them when dining out.
✔ "Is this vegan?"
これはヴィーガンですか?
Kore wa vegan desu ka?
✔ "Does this contain fish stock?"
だし(魚)は入っていますか?
Dashi (sakana) wa haitteimasu ka?
✔ "No fish, no meat, no eggs, please."

Sakana, niku, tamago wa irenaide kudasai.
✔ "Can you make it without dashi?"

Most restaurants will be honest, but many cannot remove dashi because their broth is pre-made.

Luckily, Japan has many ingredients that are naturally vegan:
✔ Tofu
✔ Fresh vegetables
✔ Seaweed
✔ Rice dishes (plain onigiri, but check fillings)
✔ Edamame
✔ Soy-based seasonings
✔ Pickles without dashi
But the safest option is to choose fully vegan restaurants or experiences.
