Are you searching for more Japanese Neo Soul / Blue / Jazz, then check out this group called Crime of Conscience from Japan.
I happened to see them today at the Oktober festival in Japan at the Zama US base Open Day. What an awesome group and Tomoko was crazy of the keyboard. They have an album out which they were selling on the day and signing.
It seemed very Blue sounding at first but then kind of broke out into more of a jazzy sound as they got warmed up.
Check them out below.
