From the same article mentioned by Otokonoyama above:
When Akebono was in a coma last year, Musashimaru was hospitalized in Tokyo. Musashimaru fell ill during a golf outing in Nara. He then received a kidney transplant from his wife, Masami, a former hula instructor.
“I feel good and the doctors say I’m doing well,” said Musashimaru, who turned 47 Wednesday. “Thanks to my wife.”
When the May tournament in Tokyo concludes he says he will resume “house shopping for a bigger place.”
He currently has a three-story building in the Edogawa section of Tokyo where he, his wife and 3-year-old son Joey live upstairs and a growing stable of apprentice wrestlers live and train on the lower floors.
With 19 fledgling sumotori, including nephew Mamo, a makushita-division wrestler who is the ranking sumotori in the stable, “I need a bigger place if I’m going to bring in some more guys.”
It is amazing that Musashimaru has been this successful at recruiting. He has surprised me several times since he retired as a rikishi. I hope he keeps on surprising me. Maybe the next surprise will be a sekitori. :)
