> Tokyo Metro is one of two rapid transit operators in Tokyo, Japan (the other being Toei Subway)I'm assuming this text is an AI hallucination because there are dozens of rail operators in Tokyo. Tokyo Metro is not even the largest and basically only operates an underground subway. JR (Japan Rail) operates above-ground and is much larger (and nation-wide).https://en.wikipedia.org/wiki/List_of_urban_rail_systems_in_...Just a single line of JR East's (Yamanote) moves a third as many people daily as Tokyo Metro does all by itself, and JR has over 50 lines just in Tokyo.
