Tokyo Metro (Tokyo Subway)

Tokyo’s underground trains form a crucial part of the city’s vast and efficient rail network, operated by two companies: Tokyo Metro and Toei Subway. These subterranean lines seamlessly connect with above-ground routes, making navigation through the sprawling metropolis straightforward, even for those who don’t read Japanese. The key to a smooth journey is understanding which service—metro or subway—is needed to reach your destination, ensuring you enter and exit the correct stations. This well-organized system allows visitors to explore Tokyo with ease, from bustling downtown areas to quieter, more residential neighborhoods.
