Dr. Toshiya Joshima

Dr. Toshiya Joshima (城島 俊也 Jōshima Toshiya) is one of the top members of the Tsukuba based team Purple Shadow, alongside Kozo Hoshino.

Information
Joshima is a middle aged man who works as a doctor/physician. In his spare time, he likes working with vehicles, most specifically cars. He is known as the "God Hand" for his ability to control a car precisely with just one hand on the steering wheel. He is notably one of the very few people who beats Takumi Fujiwara in a race.

Racing Style
He has an intellectual style similar to Ryosuke Takahashi. He derives personal satisfaction by pulling his punches. He is able to use wheel lifting like Takumi and can confuse his chaser by manipulating his vector. Some of his team members consider his methods very cruel, especially given the irony that he is a doctor.

Race vs Project D's Downhill Ace, Takumi
During Takumi's battle with Joshima, Takumi felt as if he were being chased by Bunta in the Impreza. Initially Joshima toyed with Takumi, hiding his true ability, trying to instil confusion and self-doubt, confident he could dominate the battle. After Joshima finally sprang his tactical trap, Takumi recovered and retook the lead. The astonished Joshima eventually had to abandon his game, and used his ultimate time attack line to pull away. Takumi broke his suspension trying desperately to catch up, and was reduced to limping down the mountain. This gave Takumi a mechanical loss, however due to the heat and exhaustion from the multiple round of the battle, Joshima was forced to stop to vomit. Because of this, Takumi was able to pass and crossed the finish line first. Despite beating Joshima to the finish, Takumi does not believe that he had won, something that Joshima agrees with.

After the race, Joshima admits that Takumi's comeback put him under so much pressure that he was forced to put his left hand back on the steering wheel, something that hadn't ever happened to him. Takumi requests a favour from Joshima, asking him to ride in his S2000 as he drives down the mountain again so that Takumi could watch Joshima's technique first-hand and hopefully improve upon his own techniques in which Joshima agreed before giving his final advice to Takumi.

Trivia

 * Dr. Toshiya Joshima is one of the few characters to have beaten Takumi Fujiwara in a race, though its disputed, as while Takumi breaking the suspension meant a victory for Joshima, since he had to pull over to vomit, Takumi technically crossed the finish line first.
