Blues lock Anthony Boric has turned his back on Super Rugby to complete a move to Japan.
The New Zealander has agreed a two-year contract with Mitsubishi Dynaboars, where he will move at the end of the current season.
"Japan is a country I have always enjoyed visiting so to be settling there for a time will be a great experience for me," Boric told reporters at a press conference.
"I am excited at the prospect of joining the Mitsubishi Dynaboars and look forward to playing my part in helping the team achieve its goal of reaching the top league as soon as possible and staying there."
Boric has won 24 caps for his country.
