Having got a taste for one-off races at the Monaco Grand Prix, Jenson Button will continue in that vein by racing for Team Mugen at the Suzuka 1000km race.
The 2009 World Champion will join Hideki Mutoh and Daisuke Nakajima, with the race taking place on August 27.
"After driving an NSX Concept-GT at Honda Racing Thanks Day last December, I became interested in racing in Super GT. I spoke with Honda and they have given me the chance to race at the Suzuka 1000km," said Button.
"As an F1 driver and a member of Team Mugen, I will push to win. I am very much looking forward to racing in front of my Japanese fans again."
Button will drive for Team Mugen for the first time on June 6 and June 7 as part of a two-day tyre test.
