Japan is one of gaming's most important epicentres. Louise Blain goes in search of the music of this key sub-genre. Featuring such composers as Koji Kondo (Super Mario Brothers), Shunsuke Kida (Demon's Souls); Yasuaki Iwata and Manaka Kataoka (Zelda: Breath of the Wild) and Kow Otani (Shadow of the Colossus). And we hear from Cody Matthew Johnson and Yoko Honda, the composers of an arresting soundtrack to the new samurai game Trek to Yomi, featuring highly authentic Gagaku music.
