YouTube led me to this. Was never a big jazz fan but was listening to some lofi Hip-Hop and this played. https://youtu.be/BFmH7moCL2c Hitoshi Suzuki - romance. After that I listened to the rest of his one and only album great stuff.
Masayoshi Takanaka's An Insatiable High (https://youtu.be/9cuxrkZeai8) is one of those albums that the algorithm pushes on everyone, and for good reason. Extremely funky. The Rainbow Goblins (https://youtu.be/MzYD56hKF-8) is also impressive - a concept album based on a children's book. I'd recommend anything 1985 or earlier from Takanaka - after that, he starts to get a little cheesy.
Another personal favorite is Naoya Matsuoka. Everything that comes up when you search his name is great, so here's a live video that won't (unless you search the kanji): https://youtu.be/-yQv7_tK3X8
