Japan-born rikishi Takakeisho reached one milestone in his career but is already looking ahead to the next, as his promotion to ozeki means he has closed in on, but not yet reached, sumo's top rank of yokozuna.

After his promotion ceremony on Wednesday, the 22-year-old from Hyogo Prefecture said he wants to pay back his supportive parents through sumo, remembering a promise he made to them that has helped him get this far since his boyhood dreams of greatness.

When he was in sixth grade, Takakeisho wrote in an essay that his goal was to become a yokozuna by the age of 20 and win the top-division championship more than 35 times.
