While the national team showed improvement under new defensive coach John Plumtree, Tatekawa said he didn't expect the Sunwolves, who to change much with Scott Hansen overseeing the Super Rugby defense.
What Tatekawa said must change, however, are the franchise's results against Australian teams with the Sunwolves playing this season in the Australian conference, although he believes having fewer jet lag issues will help that goal.
"In order to reach our target of finishing in fifth place (overall), competing against Australian teams will be key," Tatekawa said. "In particular, we want to win our home games against them, both here and in Singapore."
