> I'd be interested learning how you've come up with that - it's disinformation. i'm speaking from extensive, direct experience.
I live here and have eyes. But tell me more about "disinformation."
Tokyo metro's standard for accessibility is to have one route that is accessible from street level to the platform. That's fine, but it's a far cry from every entrance being accessible, or even just ensuring that you don't require staff support to make it through that route. Consider Takadanobaba [1] -- a major transit point that I know well. Yes, it's technically "one route", but just taking into account subway station exits (and not Seibu or JR line transfers, which are harder), it qualifies only because it has a single elevator that goes to ground. Literally every other exit is inaccessible.

yeah, that's mostly correct, but i don't see it as a barrier. i don't think an elevator needs to be slammed down next to every staircase. if there's a way in, and a way out, i consider that a win. will i lose maybe 5 minutes because the accessible entrance is not in the most convenient location that day? perhaps. but it's just that - an inconvenience.
on the staff support: i don't really see any problem here at all. in fact, i think the service that the staff provides is truly excellent. most lines have nearly level train-to-platform gaps, but if i feel like i need a ramp, i can ask the attendant at the gate, and they will arrange for someone to quickly unfold a portable ramp when the train arrives, and for someone to do the same at the destination, exactly where i arrive. (coming from the US, can i imagine this level of service at any US city? uh, yeah, no.)
i use the subway here nearly everyday - many different routes, not just touristy areas, often to small stations on the outskirts of the city, or other places i haven't been, just for fun. i don't think i've ever seen a station with only one elevator, it's always at least one platform-to-ticket-gate, and one ticket-gate-to-ground (maybe that's what you meant). the worst i've experienced has been a wheelchair-accessible stair lift or escalator (a bit dreadful, but they do work). if you want to do some random sampling, pull up a random station map and check the accessible routes.
