Yes, ORIX offers a Car2Go-style car share/short term rental system. The service is Japanese only, but here's a detailed English blog about it: https://bestlivingjapan.com/japan-carshare-orix/
While you don't need a Japanese license, it does require signing up in advance and receiving a dedicated card by mail for unlocking cars (no phone apps here), so it's not great for short-term visitors to Japan.
