Toei Subway

The Tokyo subway system is a crucial component of the city's transportation infrastructure, comprising two main operators: Tokyo Metro and the Toei Subway. The Toei Subway consists of four lines – Asakusa, Oedo, Mita, and Shinjuku – complementing the nine lines of the Tokyo Metro. While initially appearing complex, the system is well-organized with clear signage in both Japanese and English. Utilizing a rechargeable card simplifies travel across both systems, and the cost-effectiveness of the subway makes it a preferred choice for both residents and tourists. Transfers between JR lines and the subway can sometimes require navigating separate stations, even if they share a name.
