Disc 3 in record time:
Definitely: Mitsuru Soma, Satoru Umeda, Kenichi Sano, Yoshinori Tada (多田吉徳), Yutaka Ozawa (小沢豊), Toshiki Fujisawa (藤沢敏樹), Tsunehiro Terai, Hideki Matsutake
Likely: Noriko Ishioka, Katsuhiko Toyama, Setsuo Taniguchi
Maybe: Mitsuo Murakami (村上光雄), Eiichi Tanaka (田中栄一)
Stumped: 内田道子
村上光雄: I found a couple of random hits for a guitarist Mitsuo Murakami, notably on the Nozomi Aoki album 1999 A.D.
Satoru Umeda: Seems his name is occasionally misread Manabu Umeda, like here:

多田吉徳: This is the Yoshinori Tada you identified on discs 1 & 2, exact same characters. Did you miscopy something, maybe?
田中栄一: I think this is probably a different person from the engineer. I don't know if this is the same person on this album, but of all things, here's an article from a Pennsylvania paper from 1969 featuring an Eiichi Tanaka of the Japan Philharmonic Symphony Orchestra:

Noriko Ishioka: A Noriko Ishioka performed on this album:

小沢豊: I noticed accidentally while searching names in this thread that you skipped this cellist in your review. This should be Yutaka Ozawa:
[MPN] [performed on this album with Tomio Yajima and Toshiki Fujisawa].
