Tokyo - Tony Brown has taken over the Sunwolves coaching reins until the end of the season from Jamie Joseph, who has returned to New Zealand for a back operation.
Brown is also assistant to Joseph with Japan as attack coach.
“Although it was a very difficult decision to be unable to accompany the last three games of the season, it is necessary to make the best choice to achieve the goal of Japanese rugby,” Joseph said.
“I’m confident the Sunwolves will continue to evolve under the talented coach Tony Brown and support staff. I want to see their evolution tightly until the end of the 2018 season.”
The Sunwolves tackle the Bulls in Singapore this Saturday (kick-off 13:55 SA time).
They will conclude their campaign with matches against the Waratahs (Sydney, July 7) and Reds (Brisbane, July 13).
The Sunwolves are currently bottom of both the Australia Conference and the Overall standings with two wins from their 13 matches to date.
