土屋圭市
In 2010, he picked up the sponsorship with UPGARAGE in collaboration with his main sponsor DRoo-P, which also required the change of his livery to grey and yellow. He earned his 2nd win Rd.5 in Ebisu going against Ken Nomura in the finals. Some would say it was considered a revenge match as Nomura had won at Rd.3 in Ebisu for the 2004 season. He also started to enter Drift Muscle races started by Keiichi Tsuchiya from 2011. He drives the Nissan Silvia S15 instead of the AE86 in the Drift Muscle series.
