It also proved melodically rich and stylistically distinctive due to the acoustic guitar - based sound he crafted with the help of
synthesizer operator Ryo Yamazaki.
However, it developed a reputation for high quality sound manipulation through the works of two former Square employees, sound programmer Hidenori Suzuki and
synthesizer operator Junya Kuroda, on Mitsuda's projects and external ones.
He initially joined Hirosato Noda as
the synthesizer operator of Kingdom Hearts II: Final Mix +.
In 2007, Kawamori became
a synthesizer operator for another valued series, Kingdom Hearts, having exclusively worked on the Final Fantasy series up to that point.
Unique from his colleagues in that his future roles were predetermined, Kawamori was given the enormous privilege of being the principle
synthesizer operator for the Final Fantasy series.
His latest role as
a synthesizer operator was Takeharu Ishimoto's Final Fantasy Type 0, where he maximised the potential of a range of rock and orchestral pieces on the PSP.
In 1998, he and four others were employed as
synthesizer operators at Square to bring the company's sounds into the PlayStation era.
