Bath director of rugby Todd Blackadder will leave the Gallagher Premiership side to move to Japan at the end of the season.
Blackadder last year committed his future to the Gallagher Premiership side until June 2020 but has been granted an early release from his contract to become head coach of Japanese side Toshiba.
The 47-year-old said: "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.
"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.
"Our sights remain set on a top-four finish and we are all intent on making this season our best one yet."
Bath chief executive Tarquin McDonald added: "We are confident that the club can move forward and deliver on our long-term plan with solid foundations and a system that is ready to accommodate such change.
"I am pleased that we have been able to support Todd's decision knowing it is right for him and his family.
"I have said before that it is a mark of Todd's special and unique character, rare among coaches, that we have been able to bring about such positive change to the culture of our club whilst he has been at the helm. Todd leaves us a stronger club than the one he joined three years ago.
"He has been a pleasure to work with and I would like to thank him not only for his contribution of what has gone by but also for what is yet to come. I wish him every success for the future."
