> 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).

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.
TIL, thank you for the reference! I completely missed that while building out Tokyo Metro, I've never been to japan (though I want to) and as such, I'm not familiar with the vast systems. It took long enough to get data to build tokyo's metro, and I based that title off several articles I had read. When I have some time this week, I'll work to add the rest of the subway systems in region and update the title. ty!
