Jenson Button will race full time next year with Honda, having secured a deal to compete in Japan's Super GT series.
The 2009 world champion, who made a one-off return to F1 earlier this year in Monaco, had been in search of a competitive program for 2018, setting his sights on racing either in America or Japan.
Button was initially considered for an IMSA drive in the US with Penske-Acura, but ultimately he was not included in the team's line-up.
Last August, the 37-year-old took part in Super GT's headline event - the Suzuka 1000km race, an experience which undoubtedly wet his appetite.
"I'll be racing for Honda and have a contract to race with Honda in Super GT in 2018," Button said.
"It's been a dream for the last couple of years, I love the category. I did one race in Suzuka this year, and it got me very excited.
"I'm very excited about the new season. There's a lot of testing to be done to feel comfortable and hopefully improve the package and go out next year and be competitive."
Button made the announcement during its end-of-season Honda Racing Thanks Days at Motegi, but provided no details about the team for which he shall be driving.
