Leicester Tigers winger Alesana Tuilgai has revealed that he will leave the club at the end of the season.
The 31-year-old, who plays alongside younger brother Manu at Welford Road, is expected to ply his trade in Japan at the start of the next campaign.
"It's very sad that I'm leaving the club, [and] leaving Manu," Tuilagi told BBC Radio Leicester. "Making the decision was really tough, but it's a good opportunity for me and my family.
"I've been here ages. I'm used to the area and the club, and I feel comfortable playing at Welford Road.
"I've been thinking about my final game for a long time. And it's not just about leaving Manu. I've known a few of the boys for a long time. We've been playing together and having fun together for a while, so it's very sad."
Tuilagi has scored 44 tries in 105 appearances for the Aviva Premiership side following his move in 2004.
