If you like Nujabes and Ninja Tune I also suggest checking out Shigeto
Edit:
More less well-known chill music producers (who all happen to be Asian): Bahwee
Beat Culture (A bit of nepotism as I went to primary school with him)
Giraffage
Giraffage is great, my roommate actually knows him because they both are really frequent users in a small forum. My roommate first introduced him to me by the name of Robot Science. You might like it, it´s definitely not as good as Giraffage though.
Nice, I found out about and became a fan when he was on tour with XXYYXX, especially after this collab. Slow Magic opened for them.
Man, I love Shigeto´s Full Circle album. He just uses so many great samples and beats. You should listen to some Knxwledge too, here´s my favorite https://www.youtube.com/watch?v=8Bw84JJCelg
Damn, that sounds dope as hell. I just fell in love with Bibimbap, the song is in a way really out of tune, but works out perfectly.
