Hiroya Okuyama (奥山 広也 Okuyama Hiroya) is the number 1 driver or Zero 1 of Team Spiral.
Okuyama too believes in Ikeda's "Zero Theory" and is disappointed when he won't be able to use his car's full potential due to the rain.
Okuyama, unlike Ikeda, is very arrogant and confident in his abilities. He also refuses to greet Project D upon meeting them.
His battle against Takumi is raced in the team's first fog battle, but the result was similar to Takumi's battle against Nobuhiko of the Saitama Alliance: Takumi used half his potential until the first hairpin, where he left Okuyama behind.
