Maya Yoshida has signed a new three-year contract to remain at Southampton beyond the 2017/18 season.
The defender, whose current deal was set to expire at the end of the season, has extended his stay until 2020.
Yoshida joined Southampton five years ago and has made 138 appearances for the club since, and last season he became the first Japanese player to play 100 Premier League games.
"There was no reason to leave the club,” said Yoshida. “I have been here for five years. In that time, I have had difficult moments, good moments – everything.
"I feel like it's my home and I'm very happy to continue my journey with Southampton. It's a new chapter for my career."
Yoshida was the beneficiary of Jose Fonte’s departure from St Mary’s and has fully grasped the moment, highlighting his own character as a professional.
“We are extremely pleased to have reached a new agreement with Maya, who is a vital part of our squad, not only on the pitch, but off it,” Vice Chairman (Football) Les Reed said.
“Maya is an excellent example for any young professional to follow and it was important to ensure that we extended our commitment with him.”
