At the age of 16, Miyoshi debuted in 2011 when he composed the music for SOULCALIBUR V, making him one of the youngest composers in the gaming industry. He worked with composers such as Austin Wintory to create beautiful -- and long-lasting, JRPG soundscapes. Soon, he will be collaborating with Nobuo Uematsu for Project Phoenix, a game developed by Creative Intelligence Arts.
He is also well-known for the RPG I am Setsuna, which was released in 2016. The soundtrack relies solely on the piano, which presents a melancholy yet sweet tone. Each song is played with an elegance that compliments the snowing setting within the game.
