Shop that can perform CLA to a Leica M8 in Kansai area (Nara, Osaka, Kyoto or Kobe)?

Hi everyone, I'm currently living in the Kansai area in Japan, and my Leica M8 is in dire need of a CLA. Does anyone know of any repair shops that could carry out the work?

Thanks in advance!

Edit: I'm having issues with the rangefinder mechanism, so analog repair shops are welcome!
