In November 2002 Musashimaru tore a tendon in his left wrist, an injury which proved to be career-ending. Forced to withdraw from that tournament, the chronic problem restricted him to just a handful of appearances in the whole of 2003. Overshadowed by new yokozuna Asashōryū, he entered the July tournament but pulled out after just six days. He did not compete again until November, when after suffering his fourth defeat on the seventh day, he announced his retirement. In an interview on November 16, 2003, he revealed that he had also injured his neck while playing American football in high school and had been unable to move his left shoulder properly. Musashimaru was the last Hawaiian wrestler in sumo, ending a dynasty that began with Takamiyama in 1964 and at one point in 1996 saw four from the islands ranked in the top division. During his career he had won a total of twelve top division championships, one more than Akebono, and also won over 700 top division bouts, one of only six wrestlers to have achieved that feat to date. He officially retired on October 2, 2004, when he had his danpatsu-shiki, or retirement ceremony, at the Ryōgoku Kokugikan.
