rims, an HKS 2.2L stroker kit setup by Auto Produce Boss, Speed Glass lightweight windows, and utilizing a Holinger sequential transmission. The car was later reused for the 2005 and 2006 seasons. The 2003-spec S15 was used only for international events throughout 2005 until the car was exported to Norway in 2007. He had a very steady season and was able to keep a seeded position. He was ranked 4th overall. In 2005, he manages to win the season opener held at Irwindale once again. He also earned more victories at Sugo and Ebisu rounds to rack up his position as the series point leader. At the championship finale, he was crowned as the 2005 D1GP champion and earned the championship title by beating Masao Suenaga only by 1 point. In 2006, he switched teams from Kei-Office to DG-5 with 2005 championship car having cosmetic changes, specifically with the Kei-Office aero being removed for GP Sports' G-Sonic Evolution kit. He manages to once again win the season opener in Irwindale, earning him a nickname that some would say, the 'Irwindale Meister'. The S15 remained green until it was later repainted to blue after DG-5 collaborated with Avex's M.O.V.E, starting in Round 2 onwards. He had a steady season earning a second win at the third round in Fuji and ranked 3rd overall, however, it would be the last season that he would compete in the D1 Grand Prix. He also earned a victory for the U.K. exhibition match in Silverstone Circuit with a T-car S15, later used by Hideo Hiraoka the following year along with other D1 drivers from 2008 on-wards. The 2005 championship car would later be used by Katsuhiro Ueo (2007), Youichi Imamura (2008-2011), Yoshinori Koguchi (2012-2013), and Shinji Minowa (2014).
