I see a lot of vaporwave and similar genres of music sample from 70s-90s japanese pop music, but a lot of great instrumental music seems to kind of go under the radar. Himiko Kikuchi is one of my favorite artists right now along with Casiopea. Some of their works have gotten a lot of attention on youtube but their stuff as a whole doesn't seem to be all that popular. If you want to give some of their stuff a listen "All Right" and "Cross point" are some great albums.
