Nobuhiko Akiyama

Nobuhiko Akiyama (秋山 延彦 Akiyama Nobuhiko, known as Nobu in the English localisation of the Arcade Stage games) is the leader of the Northern Saitama Alliance and Wataru Akiyama's cousin.

Saitama and Ibaraki Arc
He is very intelligent and analytical, but his skills as a driver are comparatively very poor. Because of this, he usually recruits other highly skilled drivers and uses his technical data to further tune their cars according to each course. Nobuhiko did race against Takumi Fujiwara once on the downhill, but he was left behind after the first hairpin and only because Takumi was letting him keep up, upon Ryosuke Takahashi's instruction. Upon knowing he is no match for him, he and Wataru later recruited Sakamoto, a rally racer to the Northern Saitama Alliance in an attempt to defeat Takumi Fujiwara.
