Is there Uber in Japan? Japan travel transportation taxi

Is there Uber taxi in Japan? It's only in Tokyo as of 2016. You can call for uber via tripadvsior and google map. Uber is not well known nor welcomed in Japan yet. Just take a look at the taxi culture in Japan! All taxis are black cars driven by professional senior taxi drivers who are also older, more traditional, wear white gloves, uniforms and hats, polish their cars to the max to the point that it's shiny and operating only using automatic doors. It's a long way before Uber breaks into the Japanese taxi industry and taxi transportation culture.
