Early life
Early life
Okabe started taking electric organ lessons as a child, covering contemporary pop and film music. Although he did not learn from teachers, he would develop his musical skills through joining a band and recording music. He has cited Henry Mancini, Ennio Morricone, and Ryuichi Sakamoto as being some of his musical influences. He studied at Kobe Design University.
Namco and early freelance work (1994–2004)
Namco and early freelance work (1994–2004)
After graduating from university, Okabe joined Namco in 1994, with his first work being a handful of tracks for medal game Spiral Fall. He would also work on titles such as Air Combat 22, along with some arrangements for the PS1 version of Tekken 2. This would lead to him scoring Tekken 3 along with fellow Namco composer Nobuyoshi Sano. Both composers chose to make big beat music for the game as it both fitted the atmosphere of the game and had not been done in video games before. During the game's production, he became ill. He and Sano would also work on Tekken Tag Tournament with other composers in 1999. In the later years of his employment at Namco, Okabe did a handful of freelance composing and remixing gigs, such as composing background music for commercials and other video productions, as well as remixing pop songs with Junichi Soma. He left Namco in 2001 to become a fully independent freelancer; while he feels that the game industry served as an outlet for him to create music, he wanted more freedom to work on non-game projects. In addition to further work on game projects and remixes, he also composed and arranged a number of songs for various artists, such as Ryuichi Kawamura. However, being freelance resulted in him losing a lot of social trust, such as being unable to change residence or sign up for a credit card.
Monaca (2004–present)
Monaca (2004–present)
After struggling as a freelancer, Okabe founded music production studio Monaca in 2004. Although it originally consisted of just Okabe, he would later be joined by ex-Namco composers such as Satoru Kōsaki, who also wanted to work on non-game projects. To this day, the studio frequently composes for both video games and anime, as well as other types of media such as live action films. In 2010, he served as the lead composer for Nier, being assisted by fellow Monaca composers Kakeru Ishihama and Keigo Hoashi, along with Cavia composer and sound director Takafumi Nishimura. To fit with the game's story, he composed a soundtrack that he describes as "mysterious, delicate, and ephemeral". The team were given creative freedom, while working under Yoko Taro's direction, who attended the same university as Okabe and was a 3D graphics designer at Namco. The composers worked with English-Japanese singer Emi Evans, who wrote and sang the lyrics present in the game's songs. As Taro wanted the game's musical direction to be well represented in the game, the team participated in the project as early as the planning stages, leading to Okabe composing three songs. Various musical directions were also explored later in the game's development. Okabe, Ishihama and Hoashi would go on to compose for its 2017 sequel Nier: Automata, while being joined by Kuniyuki Takahashi. Its music was acclaimed; it won the award for "Best Score/Music" at The Game Awards 2017, and was a runner-up for "Best Original Music" at IGN's Best of 2017 Awards. In 2019, he composed for battle royale game Cyber Hunter with fellow Monaca composer Ryuichi Takada, both working with violinist Yu Manabe.
