The subway system is sprawling but, as someone who doesn't know any Japanese, I've never had any real trouble navigating it. Didn't know about woman-only cars but I assume most Japanese would take it as just another clueless foreigner and wouldn't think much else about it.

The Tokyo subway was never difficult to navigate. But as someone who has recently returned from a trip to Japan for the first time since COVID I can tell you they've made substantial improvements since (mostly as a result of the run up to the Olympics).
There is now substantially more English signage on the subway than ever before. The ticket machines even now have extensive English language menus.
