Yuichi Tachibana

Yuichi Tachibana (立花 祐一 Tachibana Yūichi, "Boss") is the boss of the gas station that Takumi and his friends worked in. An old friend of Bunta's and a racer in his youth, Yuichi acts like a father figure to the Akina Speed Stars.

His Toyota Camry appears in the first episode of the Initial D First Stage while Takumi (assumed to be Bunta by Yuichi) passes Yuichi on a downhill run in Akina.

In Fifth stage, Yuichi is not present. Later, He is here in Final stage.
