About T's TanTan
T's TanTan is the restaurant that put vegan ramen on the map for Tokyo travelers. Born from the all-vegan T's Restaurant in Jiyugaoka, every bowl is free of meat, fish, dairy and egg — yet the sesame-rich tantanmen is so satisfying it wins over plenty of non-vegans too.
What makes it unbeatable for visitors is the location: it sits inside the ticket gates at Tokyo Station's Gransta (Keiyō Street), so you can grab a proper plant-based meal between trains without ever leaving the station. Order at the counter, sit, slurp, go.
