I don't know. Personal opinion follows, YMMV: I've been to Tokyo recently. The subway system is much less convenient than, let's say, NYC. There are multiple operators, you need to purchase tickets separately to each one, it's not obvious for a tourist to understand the reasoning, and you can't pay with credit card (in 2023...), You need to either purchase a special card from a desk, or pay cash. In 2023. I consider that a hassle (it actually surprised me, I envisioned Tokyo as the city of the future. It is indeed, only it seems to be the future of 1993, sadly not of 2023).
