Height: 162 cm (5'3") Car: Toyota Corolla Levin SR (AE85) (color: High Tech White)

Itsuki is Takumi's best friend and a member of the Akina SpeedStars. Itsuki provides the comic relief in the series, as he is the most enthusiastic of the whole street racing scene. Wanting to be more like Takumi, he accidentally buys an AE85 (Known as Hachi Go, "Eight-Five") Corolla Levin mistaken it for an Hachi-Roku (Eight-Six). This upsets him until Takumi takes him for a drive (ultimately racing it downhill), demonstrating that the driver's skill can make a difference. With a car, he is a self-proclaimed member of the Akina SpeedStars. He eventually purchases a turbocharger for his Hachi-Go.
