Former All Blacks hooker Mark Hammett is favoured to coach the Japanese Sunwolves in their first foray into Super Rugby and another former All Black, Jamie Joseph, is being lined up to succeed Eddie Jones as Japan's national coach for the next four seasons.
National Japanese dailies report that negotiations with Hammett are in the late stages with an official announcement about the Sunwolves' playing roster and some staff expected on Monday.
The media are also saying the Japan Rugby Union have picked Joseph from a shortlist of five contenders to coach the national side with negotiations now underway with Joseph and the Highlanders about him continuing to coach the Super Rugby champions.
Attempts to reach both Joseph and Hammett to discuss their rugby coaching futures were unsuccessful.
Hammett moved from the Hurricanes to be director of rugby at Cardiff in 2014 but the club agreed to release him six months into his three-year deal for personal reasons. He has been appointed assistant coach of the Tasman Makos provincial side next year.
