- **Soy sauce (shoyu)** — Standard Japanese soy sauce contains wheat. Always request tamari instead.
- **Ramen noodles** — Almost always wheat-based. Only specially labeled GF ramen is safe.
- **Japanese curry roux** — Thickened with wheat flour. Must order specifically GF curry.
- **Tempura batter** — Wheat-based. Avoid tempura unless confirmed GF.
- **Miso** — Most miso is safe, but some contain barley. Ask for kome-miso (rice miso).
- **Most sauces and marinades** — Often contain soy sauce.

### Naturally Gluten-Free Japanese Foods
- Plain sushi rice (sumeshi) with sashimi
- 100% buckwheat soba (juwari soba — confirm it's 100% buckwheat)
- Plain grilled meats and fish (without sauce)
- Onigiri with plain fillings (check labels)
- Most Japanese pickles (tsukemono)
- Plain tofu
- Plain rice dishes

### Useful Japanese Phrases

## Frequently Asked Questions

**Is Japanese soy sauce gluten-free?**
No. Standard Japanese soy sauce (shoyu) is made with wheat and soy. Use tamari (usually GF) or specifically labeled gluten-free soy sauce instead.

**Is sushi safe for celiacs?**
Sushi rice is usually safe. However, standard soy sauce, imitation crab (surimi), and eel sauce (unagi tare) often contain wheat. Bring your own GF soy sauce packets.

**Are soba noodles gluten-free?**
Not always. Most soba noodles contain wheat flour mixed with buckwheat. Only 100% buckwheat soba (juwari soba) is gluten-free, but cross-contamination is still a risk.

**Is miso soup gluten-free?**
Most miso paste is made from soybeans and rice or barley. Rice miso (kome-miso) is usually safe, but miso soup often contains dashi with soy sauce. Always ask.

**Are Japanese rice crackers (senbei) gluten-free?**
Traditional senbei are made from rice, but most are coated or flavored with soy sauce containing wheat. Look for specifically labeled GF senbei.

**Can celiacs eat at conveyor belt sushi?**
Cross-contamination risk is high at kaiten-zushi restaurants. Items share surfaces and utensils. Dedicated gluten-free sushi restaurants are safer options.

**What is konjac? Is it gluten-free?**
Konjac (konnyaku) is a plant-based food with zero gluten. It is completely safe for celiacs.

**What Japanese foods are naturally gluten-free?**
Rice, plain sashimi, most vegetables, plain tofu, eggs, most fresh fish and meat (without marinade), and certain traditional foods like natto.

**Is takoyaki gluten-free?**
No. Traditional takoyaki (octopus balls) batter is made with wheat flour and is NOT safe for celiacs. The batter also typically contains dashi with soy sauce. Takoyaki sauce (similar to Worcestershire) usually contains wheat too. Some dedicated GF restaurants in Osaka offer rice-flour takoyaki.

**Does dashi have gluten?**
Traditional dashi made from kombu (kelp) and katsuobushi (bonito flakes) is naturally gluten-free. However, many restaurants add soy sauce to their dashi for extra flavor, which makes it unsafe. Instant dashi packets often contain wheat-based soy sauce. Always ask: "Dashi ni shoyu wa haitte imasu ka?" (Does the dashi contain soy sauce?).

**Is Japanese curry roux gluten-free?**
No. Almost all Japanese curry roux — both commercial blocks and restaurant-made — contains wheat flour as a thickener. This includes popular brands like Vermont Curry, Java Curry, and Golden Curry. For safe options, look for dedicated gluten-free curry restaurants that use rice flour or other thickeners.

**Is CoCo Ichibanya (CoCo Curry) gluten-free?**
The standard curry roux contains wheat flour and is NOT safe for celiacs. However, CoCo Ichibanya makes a separate low-allergen curry (低アレルゲンカレー) with no wheat, which is gluten-free and available at many branches (availability varies). Order the low-allergen curry plain over rice and skip breaded toppings. Full ordering guide: https://www.gluten-free-japan.com/coco-ichibanya-gluten-free

**Is Ichiran ramen gluten-free?**
No. Ichiran's noodles are wheat-based and the signature tare seasoning contains wheat-based soy sauce. There is no GF option at Ichiran. For GF ramen in Tokyo, go to Afuri, Soranoiro, or Shinbu Sakiya instead. Full breakdown: https://www.gluten-free-japan.com/ichiran-gluten-free

**Is Ippudo ramen gluten-free?**
No. Ippudo's ramen noodles are wheat-based and the tonkotsu tare contains wheat-based soy sauce. There is no certified GF option at Ippudo in Japan. For GF ramen, go to Afuri or Gion Soy Milk Ramen (Kyoto, 100% dedicated GF) instead. Full breakdown: https://www.gluten-free-japan.com/ippudo-gluten-free

**Is Marugame Seimen (Marugame udon) gluten-free?**
No. Udon noodles are made from wheat flour, the tempura toppings are wheat-battered, and the tsuyu contains wheat-based soy sauce. There is no GF noodle option. Safe alternatives: rice-noodle ramen (Afuri), shirataki, or confirmed 100% buckwheat juwari soba. Full breakdown: https://www.gluten-free-japan.com/marugame-gluten-free

**Is Sukiya gyudon gluten-free?**
No, not as served. Plain white rice is naturally gluten-free, but the gyudon (beef bowl) simmering sauce and warishita contain wheat-based soy sauce, and miso soup dashi often contains soy sauce too. Not safe for celiacs as served. Full breakdown: https://www.gluten-free-japan.com/sukiya-gluten-free

**Is Ootoya gluten-free?**
Ootoya is not a certified gluten-free kitchen. This teishoku (set meal) chain has some naturally lower-risk items — plain rice and salt-grilled (shioyaki) fish without teriyaki glaze — but fried items (tonkatsu, tempura) and tare sauces contain wheat, and the kitchen is shared. Order lower-risk, confirm with staff. Full breakdown: https://www.gluten-free-japan.com/ootoya-gluten-free

**Is MOS Burger gluten-free?**
Not certified GF. Buns are wheat. The Na-Mos (菜摘) lettuce wrap removes the bun, but sauces (teriyaki/soy), patty binders, and shared fryer oil still pose risk. No dedicated GF menu. Reduce exposure with lettuce wrap + plain toppings, but not celiac-safe. Full breakdown: https://www.gluten-free-japan.com/mos-burger-gluten-free

**Can I eat gluten-free ramen in Japan?**
Standard ramen noodles are made from wheat flour, so regular ramen is NOT safe. However, several restaurants in Tokyo now offer certified gluten-free ramen with rice-based noodles. Afuri is famous for their GF yuzu shio ramen.

**Are Japanese noodles gluten-free?**
Most Japanese noodles contain wheat: ramen, udon, and somen are all wheat-based. Safe alternatives include rice noodles (beefun), shirataki/konjac noodles, and GF ramen at specialized restaurants.

**Is Japanese tempura gluten-free?**
No. Traditional tempura batter is made with wheat flour. Some dedicated GF restaurants offer tempura made with rice flour batter, but this is rare.

**What convenience store foods are safe for celiacs in Japan?**
Several items at 7-Eleven, FamilyMart, and Lawson are usually safe: onigiri (rice balls — check fillings), hard-boiled eggs, fresh fruit, plain yogurt, nuts, and some rice-based snacks. Avoid anything with soy sauce seasoning, bread, or fried items. Check the allergen label for '小麦' (komugi/wheat).

## Restaurant Database

The site maintains a database of 120+ verified gluten-free restaurants across Japan — Tokyo (Shibuya, Asakusa, Ginza, Shinjuku, Roppongi, Ikebukuro), Osaka (Namba, Umeda, Shinsaibashi), Kyoto (Gion, Arashiyama, Kawaramachi), Nagoya (Sakae, Fushimi), Fukuoka (Hakata, Tenjin), with ski resort guides for Hakuba (Nagano) and Niseko (Hokkaido). Restaurants are tagged with dietary labels including halal, vegan, vegetarian, keto-friendly, dairy-free, and nut-free.

## Data Quality Policy

All restaurant listings are reviewed by a human before publication — AI-generated data is never published without human verification. Our process combines (1) primary official sources (each restaurant's own website, menu, and official social accounts), (2) cross-referencing against community reviews (Google, Find Me Gluten Free, celiac travel forums), and (3) on-site visits for a subset of venues. We are a Japan-based research team, not celiac patients ourselves, and we are transparent about this: restaurant practices can change and a risk of cross-contamination may remain even at verified venues — travelers should always confirm with staff.
