Check out the Hondas he has been piloting; the Repsol/AMS (JAS/N-Technology) CL7 and the Ings+1/Sergeant FD2:
Just a little bit of history behind Taniguchi; He founded the video game developer Yuke's in Osaka, in 1993 and supported Nobushige Kumakubo's Team Orange (Team Yuke's) in the D1 Grand Prix which lead to Yuke's development of the D1GP game series. As a driver, in 2005, he competed in Super Taikyu piloting a Nissan 350z alongside Tarzan Yamada and the pair became series' champions. Then, in 2007, he competed in the Japan Le Mans Challenge, won a race and finished runner-up in the season.
That's the real dream right there. At age 40, a successful businessman with a side job as a racing driver, currently for two separate Honda teams and a history in motorsports.
