Hurricanes assistant coach John Plumtree has accepted a temporary job with the Japan national team for the Brave Blossoms' end of the year tests.
Plumtree would join fellow New Zealander Jamie Joseph's staff as a defence coach for a non-test match against a World XV on October 28th and then for three tests in November.
"I see my coaching future as being firmly with the Hurricanes, but I jumped at the chance when Japan approached me about the prospect of coaching at international level," Plumtree said.
"It's a great opportunity to be exposed to a new culture and new ways of coaching."
Joseph, who was named as the coach of the country's Super Rugby Sunwolves team as well last week, has already recruited his former Highlanders assistant Tony Brown to his staff. Both are contracted until the 2019 Rugby World Cup in Japan.
"Japan has a strong coaching team with Jamie Joseph and Tony Brown, and working alongside them will only add to the knowledge and experience I can add to the Hurricanes going forward," Plumtree added.
Plumtree was the forwards coach for Ireland before he returned to New Zealand to join the Hurricanes in 2015.
Japan host Australia in Yokohama on Nov. 4, then play Tonga on Nov. 18 and France in Lille a week later.
Hurricanes chief executive Avan Lee said Plumtree's involvement with Japan provided a valuable professional development opportunity.
"We are always looking at ways of developing our staff and growing their knowledge and this is another example. I'm sure Plum will benefit from the experience."
