As with previous Shenmue I & II releases we don't have complete composer credits.
I would love to have a complete composer breakdown, but I don't know if SEGA even knows who did which track.
Here are the credits from the game:
Shenmue I : Takenobu Mitsuyoshi, Yuzo Koshiro, Ryuji Iuchi, Takeshi Yanagawa, Satoshi Miyashita, Osamu Murata
Shenmue II: Takenobu Mitsuyoshi, Yuzo Koshiro, Ryuji Iuchi, Takeshi Yanagawa, Satoshi Miyashita, Koji Sakurai, Masataka Nitta, Shinji Otsuka, Fumio Ito, Megumi Takano, Osamu Murata, Shinichi Goto
