He is a racer from Saitama, his home course is Shomaru pass. He has a cousin and a Sister. He actually looks very similar to Takumi Fujiwara, the protagonist, he has a similar hairstyle, and they both drive 86s. He is very serious when it comes to racing, often over exaggerating and getting angry when he gets lied to. He put a turbo in his AE86 Corolla Levin. Wataru Akiyama (known as Aki in the Tokyopop dub of Second Stage) was one of the first racers from Saitama to actually race against Takumi with his turbocharged Levin; he appeared later in the Project D arc, this time replacing the turbocharger with a supercharger for more linear acceleration and to avoid Turbocharger lag. Wataru is a skilled driver who honed his skills on the treacherous Shomaru Pass. He came to Gunma in hopes of facing new racers to challenge, as well as to watch over his sister Kazumi, who just got a job at a hotel with her aunt. He was first seen appearing at Akagi to spectate the battle between Ryosuke Takahashi and Kyoichi Sudo.
