sentences:  It was not until mid-2006 that Miyabiyama was able to make his first sustained challenge for promotion to "ōzeki" since his demotion five years previously.In May at "sekiwake" rank he produced a superb 14–1 record, only losing the championship on the last day in a playoff to then-"ōzeki" Hakuhō.There was speculation that another strong performance in July 2006 would see him return to "ōzeki", but he got off to a poor start, winning only three bouts in the first seven days, and though he recovered somewhat to post a 10–5 score, it was not considered good enough.
