After what seemed a promising 2009 - when he played all of his eight tests, scoring tries against South Africa and Italy - Ross' career has nose-dived.
He seemed ideal at the time - a ball-winning lineout lock who was highly mobile and who possessed new age skills like the ability to beat a man; even a bit of a kicking game.
But word began to filter out of the All Black camp that all might not be well in two of a lock's core duties - pushing in the scrum and the grunt work at breakdowns. At the end of 2009, he was left out of the team to play Australia in Wellington and, a few weeks later, he was told he would not be travelling to Europe on the end-of-year tour. The reason given publicly was that it was best for him to bulk up at home.
His decline then snowballed. He was left at home when the Crusaders went to South Africa last year and making the Canterbury provincial side seemed to be as much as he could hope for. He got a Super Rugby reprieve when the Chiefs picked him up this year. He played in seven of the first eight Chiefs games (they lost three of the first four) but was relegated to the bench in South Africa for the matches against the Lions, Bulls and Stormers - and was not seen for the rest of the season, not even on the bench, except for the 18-18 draw with the Hurricanes.
"He made the decision to go up to Japan about halfway through the Super season," said his agent, Simon Porter.
While Ross is the most high-profile omission, respected Bay of Plenty loose forward Colin Bourke was also not selected by the Chiefs and is also said to be heading to Japan. Other well-known players already overseas include Taniela Moa, Aled de Malmanche, Sitiveni Sivivatu, Jared Payne, Joe Rokocoko, Luke McAlister, John Afoa, Stephen Brett, Neemia Tialata, John Schwalger, Kahn Fotuali'i, and first fives Mike Delany and Matt Berquist.
