Eating Vegetarian in Japan Is Harder Than It Looks — and Easier Than You Fear
A bowl of vegetable udon in Japan almost certainly contains fish. So does the miso soup, the simmered vegetables, the tamagoyaki, and the innocuous-looking dipping sauce. Dashi — stock made from bonito flakes and kelp — is the base flavor of the entire cuisine, and it's invisible on a menu. This trips up vegetarians constantly. But Japan also has a 1,200-year-old fully vegan culinary tradition, and once you know what to ask for, you eat extremely well.

The Dashi Problem Japanese cooking builds nearly everything on dashi, most commonly katsuo-dashi made from dried, smoked skipjack tuna. It's in soup bases, noodle broths, simmered dishes, savoury egg custards and many sauces. Staff genuinely often don't consider it "fish" in the sense a visitor means, which is why "no meat, no fish" can still produce a bowl of bonito broth without any dishonesty on anyone's part. The request that actually works is specific: state that bonito stock is also not acceptable, and ask for kombu-dashi — the kelp-based alternative — only. That phrase is what gets a dish that is actually free of fish.
Shōjin Ryōri: The Original Vegan Cuisine Buddhist temple cuisine, developed alongside Zen monasticism from around the 13th century, excludes all animal products — and also garlic and onion, on the grounds that they inflame the passions. What's left is an extraordinary discipline: kombu and shiitake dashi, sesame tofu, tempura of mountain vegetables, pickles, and rice, served in a formal sequence. Temple towns like Koyasan serve it to overnight guests as a matter of course. The best place to eat it is a temple lodging, a shukubō, and it is not a compromise meal — a great deal of skill goes into a deliberately narrow ingredient list.
The Regional Bright Spots Kyoto's yudofu and obanzai traditions, Nagano's soba and mountain-vegetable cooking, and Okinawa's vegetable-forward home food all give you room to work with. Big cities now have genuine vegan ramen and dedicated restaurants, but the countryside — where the eating is otherwise best — is where you'll need your phrases.
The Practical Middle Path Many travelers who are strictly vegetarian at home decide in advance whether they'll accept dashi for the trip. There's no right answer, but deciding beforehand — rather than negotiating at each table — makes the whole three weeks calmer.
What Works Day to Day Outside temples, the reliable categories are: shōjin and vegan restaurants in the big cities, which are now reasonably common; Indian restaurants, which are everywhere and understand the request; soba shops if you confirm the dipping sauce; and convenience stores, where plain rice balls, plain tofu, natto and fruit fill gaps.
Be careful with two specific traps. Vegetable tempura is frequently fried in the same oil as seafood, and rice balls that look vegetarian often contain bonito flakes as a seasoning rather than as a visible filling. Reading a couple of ingredient characters, or carrying a written card, resolves both.
The Card The single most effective tool is a card in Japanese listing what you do not eat, including bonito stock, and showing it rather than explaining. It removes the language problem and, more importantly, removes the category problem — you are not asking someone to interpret a foreign word, you are handing them a list.
Places Named in This Story
- 1Say that bonito stock is also not acceptable, explicitly. Saying only vegetarian will frequently get you a dish built on fish.
- 2Carry a written card in Japanese and show it rather than explaining. It solves the language problem and the category problem at once.
- 3Book a temple lodging, ideally at Kōyasan, for shōjin ryōri. Twelve centuries of vegan cooking with nothing apologetic about it.
- 4Ask about the frying oil for vegetable tempura. It is very often shared with seafood.
- 5Check rice balls for bonito flakes used as seasoning rather than filling. They do not look like fish and they are.
- 6Use Indian restaurants when you are tired. They are everywhere and they understand the request immediately.
Temple lodging is worth doing for its own sake regardless of diet, and Kōyasan pairs directly with the Kumano pilgrimage routes below it. Our food writing covers the seasonal vegetable traditions that shōjin cooking draws on, and the reading-a-restaurant guide helps you spot the doors worth trying.
