Recent findings (audit lane, verbatim)

Atsuko Hashimoto — The entry states that in 2002, drummer Jeff Hamilton heard about her from other musicians while touring Japan with Diana Krall, but Jeff Hamilton did not tour Japan with Diana Krall in 2002; Diana Krall's touring drummer at that time was generally not Jeff Ham

Norihiko Hibino — Hibino graduated from Berklee in 1998, not 1997.

Norihiko Hibino — The entry's phrasing about moving to Kansas City immediately after Berklee to start a solo career is inaccurate; he worked as a session musician and later for a production company before joining Konami.

Masayuki Hiizumi — Hiizumi did not compose Tokyo Jihen's debut single 'Gunjō Biyori'; the single was composed by Ringo Sheena.

Masayuki Hiizumi — Hiizumi's solo debut album as H Zett M was titled '5+2=11', but it was released in 2008, not 2007.

Masato Honda — The entry states Honda left T-Square after Blue in Red for unknown reasons, but the reason is known (to pursue a solo career).

Masato Honda — The entry lists the soundtrack for Mega Man X, but Honda contributed to Mega Man X4, not the original Mega Man X.

Akira Jimbo — The entry states Jimbo joined Casiopea in 1980, but established canon records him joining in 1981.

Akira Jimbo — The entry says Jimbo's first stint with Casiopea was 1980-1989, but it should be 1981-1989.

Osamu Kitajima — The entry states that Kitajima's debut album 'Benzaiten' was released in 1974 on Island Records, but the album 'Benzaiten' was actually released in 1976 on Island Records.

Osamu Kitajima — The entry says Kitajima earned a doctorate in music therapy in 2004, but there is no widely known or verifiable record of him holding a doctorate in music therapy; this appears to be an invented or unsubstantiated claim.

Toshinori Kondo — The entry states Kondo moved to Amsterdam in 1993 to start 'Blow the Earth,' but Kondo moved to Amsterdam earlier, around 1990, not specifically in 1993.

Toshinori Kondo — The entry says Kondo was a former member of Praxis, but he was not a member; he only collaborated with Bill Laswell.

Mikio Masuda — The quartet listed for the 1973 Burg Altena performance is incorrect; the actual lineup was Terumasa Hino's quartet with Mikio Masuda, Motohiko Hino on drums, and a bassist (often Yoshio Ikeda), not Shunzo Ohno.

Mikio Masuda — The claim that Masuda recorded 'Black Daffodils' in 1996 with Ron Carter and Lewis Nash is unverified and likely incorrect; no such album exists in his known discography.
