 Wakakirin is the third member of Oguruma stable to make his top division debut, following Takekaze and Yoshikaze.Wakakirin achieved ten wins in his top division debut, a feat that normally wins the Fighting Spirit Award, but he missed out, the prize going to Baruto instead.He was promoted to what was to be his highest rank of "maegashira" 9 for the January 2008 tournament, but disappointing scores of 4-11 there and 6-9 in March meant he was demoted back to the "jūryō" division.
