Eating Vegetarian in Japan Is Harder Than It Looks — and Easier Than You Fear

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.

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 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.

The Problem Is Dashi, Not Meat Avoiding visible meat in Japan is easy. The difficulty is invisible: katsuo-dashi, stock made from dried bonito, is the base of an enormous proportion of savoury cooking — miso soup, noodle broths, simmered vegetables, dipping sauces, egg dishes. A dish can be entirely plant-based in its visible ingredients and still be built on fish.

This is why saying you are vegetarian frequently produces a dish with fish stock in it. The category does not map cleanly, and the request that works is specific: state that bonito stock is also not acceptable. Kombu-dashi, made from kelp, is the vegan alternative and it does exist — the phrase to know is that you want kombu-dashi only.

The 1,200-Year-Old Answer Japan also has one of the world's oldest developed vegan cuisines. Shōjin ryōri is the Buddhist temple cooking tradition, which excludes all animal products and, in its stricter forms, the alliums as well, and it has had more than a millennium to become sophisticated rather than apologetic.

The best place to eat it is a temple lodging — shukubō — and Kōyasan is the obvious destination, where a substantial number of temples take overnight guests and serve the meal as a matter of course. Sesame tofu, mountain vegetables, simmered dishes and a great deal of skill applied to a narrow ingredient list. It is not a compromise meal.

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.
