🟢 Vegan What does this label mean?
Last verified: July 5, 2026
If you land at Tokyo Station hungry — jet-lagged, luggage in hand — this is the answer. T’s Tantan serves rich, sesame-loaded vegan tantan-men (spicy dan dan noodles) inside the ticket gates of Tokyo Station, so you can eat a genuinely satisfying bowl of Japanese noodles minutes before your Shinkansen departs. It’s one of the easiest and most reliable vegan meals in Japan.
What We Verified
- Fully plant-based menu — the restaurant’s official website states it uses no meat, no seafood, no dairy, and no eggs. The same statement appears on the official page of GRANSTA (the Tokyo Station shopping facility that hosts the restaurant). Confirmed on both sources, July 5, 2026.
- Location — inside the JR ticket gates, Keiyo Street area, Tokyo Station (Marunouchi 1-9-1, Chiyoda). You need a valid JR ticket or platform ticket to reach it.
- Hours — 10:00–22:00 daily (may change during major holiday periods), per the GRANSTA official page.
What We Could Not Confirm
- Exact menu prices are not published online — expect a mid-range ramen price (roughly ¥1,000–1,500 per bowl).
- The detailed composition of the soup base is not published (the no-animal-products policy itself is official).
- Use of alliums (garlic, onion) is unconfirmed — if you follow an oriental vegan diet, please ask at the counter.
What to Order
The signature golden sesame tantan-men (金ごまたんたんめん) is the dish this shop is known for — a creamy, nutty, gently spicy bowl that regularly convinces non-vegan travelers. Seasonal bowls and sides rotate.
