Toranosuke Takagi
Button became interested in Super GT in about 2011, and discussions with Honda led to his series debut at the 2017 Suzuka 1000km in a NSX-GT for Team Mugen with teammates Hideki Mutoh and Daisuke Nakajima. The trio finished 12th following two penalties and two tyre punctures. He also considered racing as a third driver for Acura Team Penske's IMSA SportsCar Championship team, but was rejected. Button drove the full 2018 Super GT Series for Team Kunimitsu in the No. 100 GT500-class Honda NSX-GT alongside Naoki Yamamoto; Button wanted to drive a Bridgestone-shod car and drivers recommended Yamamoto because he speaks English. Button's team helped him to communicate better, adapt to the series and its culture. He and Yamamoto won at Sportsland Sugo and took two-second-place finishes to enter the season-ending race at Twin Ring Motegi equal on points with the TOM'S duo of Ryō Hirakawa and Nick Cassidy. He held off Hirakawa to win the GT500 title by three points and was the first rookie champion since Toranosuke Takagi in 2005.
