However, at the time of Hakuba's entry in January 2000, Michinoku already had its Japan Sumo Association designated limit of foreign wrestlers.
A streak of success in 2006, culminating in the makushita championship in the last tournament of 2006, would finally grant him promotion to jūryō in January 2007.
His second appearance in makuuchi at his highest yet achieved rank of maegashira 14 was in January 2010 and he secured his kachi-koshi by Day 10, finishing on 9–6.
He was rewarded with promotion to komusubi for the July 2010 tournament, becoming the first member of the old Tatsutagawa stable to reach the titled san'yaku ranks and the first from Michinoku since the present stablemaster (former ōzeki Kirishima) took over in 1997.
Hakuba was one of 23 wrestlers found guilty of fixing the result of bouts after an investigation by the Japan Sumo Association, and he was forced to retire in April 2011.
Some tabloids in Japan had implied his romantic relationships with several female celebrities, including glamour model Nozomi Sasaki until he announced publicly in January 2010 that he had married the younger sister of fellow Mongolian rikishi Tokitenkū on October 3, 2008.
