Sunwolves captain Shota Horie has said that the new side will have to start from scratch after their humiliation against the Cheetahs in Bloemfontein.
A shocking result saw the Sunwolves concede 92 points, including 14 tries, as the Cheetahs put them to the sword.
Friday's calamitous outing was by far the worst result for the Sunwolves so far in their first season, and they remain without a win after seven games as they head back to Tokyo to face the Jaguares.
Horie mentioned that the Sunwolves' conditioning had been an issue but wouldn't use it as an excuse, underlining that Mark Hammett's side need to hit the restart button and improve fast.
"It was a difficult result and we need to rebuild and work hard," Horie told Japanese media.
"We are a little bit fatigued but we can't use that as an excuse. It's going to come down to physical conditioning from here on.
"We'll have to start from scratch."
