Japan + Vegan = You Need Data More Than Anyone
Japan's food culture is incredible, but it's not vegan-friendly by default. Dashi (fish stock) is in almost everything, and staff may not understand "no meat, no fish, no dairy" in English.
With data: You can find vegan restaurants, translate menus in real-time, and show staff your dietary needs in Japanese. Without data, you're pointing at pictures and hoping.

Useful Japanese Phrases to Show Staff
Save these screenshots, but Google Translate camera mode is your best tool:
Show this to restaurant staff:
> 私はビーガンです。肉、魚、乳製品、卵を食べません。
> (I am vegan. I don't eat meat, fish, dairy, or eggs.)
> 野菜だけの料理はありますか？
> (Do you have any dishes with only vegetables?)
> 出汁は魚ですか？
> (Is the dashi made with fish?)

| City | Vegan Scene | HappyCow Listings |
|---|---|---|
| Tokyo | Excellent (Shibuya, Shimokitazawa) | 200+ |
| Kyoto | Good (temple cuisine = shojin ryori) | 80+ |
| Osaka | Growing | 60+ |
| Hiroshima | Limited | 15+ |
| Rural areas | Very difficult | Konbini is your friend |
Tip: In rural areas, convenience stores (7-Eleven, Family Mart) have onigiri with seaweed and rice, edamame, fruit, and some clearly labeled vegetable options. Not exciting, but reliable.

Why Data Matters Even More for Vegan Travelers
| Scenario | Without Data | With Data |
|---|---|---|
| Finding a restaurant | Walk around hoping to spot English menus | HappyCow shows 10 options within 500m |
| Reading a menu | Point at random items | Camera translation reveals every ingredient |
| Communicating needs | Frustrating charades | VoiceTra speaks Japanese for you |
| Emergency meal | Skip eating entirely | Find nearest konbini with veggie options |
Vegan travelers use ~30% more daily data than average tourists because of restaurant searches and translation.
