I live in Tokyo and enjoy it. It’s very convenient with its public transportation (subways & trains), shinkansen high-speed trains (going to Nagoya/Kyoto/Osaka every few minutes) and its international airport Haneda. Surprisingly, HappyCow ranked Tokyo as the world №12 vegan-friendly city in 2025 🙂
Note: Despite its name, Tokyo Disney Resort (Tokyo Disneyland + Tokyo DisneySea + hotels + shopping complex) is not in Tokyo metropolis; it’s in neighbouring Chiba prefecture.
