@ErickaSimone Apparently, Tokyo has a shortage of taxi drivers. (It's been a few years since I was last there, so I can't confirm how difficult it is to get a taxi - it used to be very easy).
Japan also regulates rideshares (Uber et al) much more - last time I was in Kyoto, I could get only a taxi using Uber (there are better apps for taxis but I hadn't set them up).
