I came across some quality photos of the stylishly purpose-built cars that make up Team 5Zigen on their blog, and thought I'd share:

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.Photos courtesy of Taniguchi's blog: http://ameblo.jp/yuke72/
