Initial D is a story about a young man and his father's Toyota Trueno AE86 (known in the US as a Toyota Corolla). 18-year old Takumi Fujiwara has been delivering tofu every single day down Mt. Akina with his dad's car ever since he was in middle school.
It's not exactly something he likes to do, but in the whole process he unwittingly masters a lot of advanced driving techniques which makes him the fastest driver down Mt. Akina. Soon Takumi catches the attention of street racers, and he gets challenged to races down Mt. Akina time and time again -- which he always manages to win. But Takumi's ultimate challenge comes in the person of Ryosuke Takahashi, Japan's number one street racer. Ryosuke has devoted a lot of time and effort in coming up with a foolproof strategy to beat Takumi, and he's got everything riding on their final showdown.
