Similar artists to Shintaro Sakamoto

[leojapanfan]

Hi there,
I am fairly new to japanese music but came across Shintaro Sakamoto who i love! And I am looking for similar music.. I don't mind male or female or bands..
So not after J-pop so to speak but this sophisticated style of japanese contemporary music. I particularly love tracks by him such as Shintaro Sakamoto - You Just Decided - YouTube
Does anyone have any suggestions? Would be much appreciated!
Thanks
