That Chakra is awesome, almost sounds like Japanese Cocteau Twins.

Probably too surface level, but both Kakashi by Yasuaki Shimizu and Utakata No Hibi by his band Mariah are amazing albums front to back, and got pretty good vinyl reissues recently if that's you're thing. Seaside Lovers and Dip In The Pool round out my "you've probably heard it, but if not go check it out" list. (...and Minako Yoshida who arranged that Toshiki Kadomatsu album you are pulling from in the OP).

Somewhat more off the beaten track (and not really City Pop as such, but similar time period and I associate these together):

Piper

The Carmets

C. Memi - Heavenly Peace

If you want to get in to Japanese No Wave and Art Rock I can probably dig up some deeper cuts.
