Japanese menus span several distinct categories: sushi (raw fish on rice), ramen (noodle soup), izakaya (small plates), kaiseki (multi-course tasting), and donburi (rice bowls). An AI Japanese menu translator like Menu Buddy explains each dish and flags the hidden allergens — soy sauce contains wheat unless it's tamari, dashi broth contains fish, and most sauces are soy-heavy.
Key Takeaways:
- Soy sauce contains wheat unless explicitly tamari — major issue for celiac diners.
- Dashi (the foundation broth in most soups and sauces) contains bonito (fish) — not vegetarian.
- Raw fish requires the restaurant's standard food-safety protocol — choose reputable places.
- Major formats: sushi, sashimi, ramen, izakaya, donburi, kaiseki, tempura.
- Vegan Japanese is possible (shojin ryori — Buddhist temple cuisine) but rare; most Japanese cuisine uses dashi.
Understanding Japanese Restaurant Formats
Sushi-ya — sushi specialist. Ramen-ya — noodle shop. Izakaya — Japanese gastropub with small plates and drinks. Kaiseki — formal multi-course tasting menu. Yakitori-ya — grilled skewers. Tempura-ya — fried specialist. Soba/Udon-ya — noodle shops. Donburi — rice bowl restaurants. Each has its own vocabulary and allergen risks.Sushi Menu Decoded
Nigiri — fish on rice. Sashimi — raw fish without rice. Maki — rolled sushi. Temaki — hand roll. Inari — sweet tofu pouch. Chirashi — assorted fish over rice. Common fish: maguro (tuna), salmon (sake), hamachi (yellowtail), unagi (freshwater eel — usually grilled with soy glaze), uni (sea urchin), ebi (shrimp), ika (squid), tako (octopus). Eel sauce (unagi tare) contains soy and sugar.Ramen Menu Decoded
Tonkotsu — pork bone broth (cloudy, rich). Shoyu — soy sauce based (clear, salty). Miso — miso paste broth (savory, sometimes spicy). Shio — salt-based (light). Toppings: chashu (braised pork), ajitama (soft-boiled egg), nori (seaweed), menma (bamboo shoots), negi (scallion). Almost all ramen contains wheat (noodles) and soy. Tonkotsu specifically uses pork. Vegan ramen is rare but increasingly available.Izakaya Small Plates
Edamame — boiled soybeans (soy, obviously). Karaage — Japanese fried chicken (gluten from coating). Yakitori — grilled skewers with tare sauce (soy). Tatsuta-age — marinated fried chicken. Agedashi tofu — fried tofu in dashi (contains fish). Tako wasabi — raw octopus with wasabi. Tsukemono — pickled vegetables.Hidden Allergens in Japanese Food
Wheat: in regular soy sauce, ramen noodles, tempura batter, panko coating, udon, somen, mirin (sometimes). Soy: nearly everywhere — soy sauce, miso, tofu, edamame, teriyaki, tare glazes. Fish: dashi broth (in most soups, miso soup, agedashi tofu, even most curries), bonito flakes. Shellfish: some dashi includes dried sardines. Eggs: tamago (sweet egg sushi), many ramen toppings, fried rice.Raw Fish Safety
Sushi is generally safe at reputable restaurants where fish is properly frozen for parasite control (US FDA requires this for fish served raw). Avoid raw fish if pregnant, immunocompromised, or in regions where standards are unclear. The reputational signals matter — a busy sushi-ya with high turnover is safer than a sleepy one.Vegan & Gluten-Free Japanese
Vegan: Inari sushi, vegetable maki (verify rice vinegar isn't sweetened with non-vegan sugar), edamame, salads with sesame dressing (verify), kappa maki (cucumber roll), avocado roll. Avoid dashi-based broths. Shojin ryori is fully vegan Buddhist temple cuisine. Gluten-free: sashimi (without soy sauce, or with tamari), rice dishes (verify no soy sauce), gluten-free soy sauce (tamari) is increasingly available at sushi restaurants.How Menu Buddy Handles Japanese Menus
Menu Buddy reads Japanese characters (hiragana, katakana, kanji) plus romaji-transliterated names and explains each dish with allergen flags. Menus often combine Japanese script with English; the app handles both. See our menu translator guide for the workflow.Frequently Asked Questions
Is all soy sauce gluten-containing?
Standard Japanese soy sauce (shoyu) contains wheat. Tamari is wheat-free soy sauce, often available at sushi restaurants for gluten-free diners — but verify.
Is miso soup vegan?
Usually no. The dashi broth almost always contains bonito (fish). Some restaurants offer vegan dashi made with kombu and mushrooms only — ask specifically.
Are sushi rolls safe for shellfish allergy?
Mostly yes, but watch for: imitation crab (kani, which is fish), tobiko (fish roe), and dashi in sushi rice (some restaurants use it). Verify before ordering.
Does Menu Buddy read Japanese characters?
Yes. The AI handles hiragana, katakana, kanji, and romaji simultaneously, plus translates and explains each dish with cuisine context and allergen flags.
