London - Bath director of rugby Todd Blackadder will leave the English Premiership club at the end of the season to become head coach of Japanese side Toshiba.
Blackadder, 47, has been granted an early release from his contract, which was due to run until 2020.
"It's been an honour and a privilege to lead the Blue, Black and White for the past three years and I'm incredibly proud of what we have achieved," Blackadder said on Wednesday.
"It might not be silverware but together we have built strong foundations and I leave knowing that the best is absolutely yet to come.
"Bath is a very special club. I'd like to thank everyone, especially the players and all of the staff.
"I also want to thank our supporters - even in the wind, rain and biting cold they are all at the Rec cheering us on. Thank you."
Bath chief executive Tarquin McDonald added: "I am pleased that we have been able to support Todd's decision knowing it is right for him and his family."
