That is incredibly cool and I'm envious.
I saw one of Musashimaru's tournament wins in Tokyo about 6 years ago, when he was still an Ozeki. That was my first visit to a sumo match although I'd enjoyed the bilingual broadcasts while visiting Tokyo. It was a very exciting tournament since he didn't clinch until the final day. I was with one other American and it was a great deal of fun being able to root for an American wrestler.
I happened to be in Tokyo last week and went to the tournament one day. Asashoryu lost that day although he ended up winning the tournament.
When I was dining at Nobu (Tokyo) around a year ago, Konishiki was there that night but, I didn't speak to him. I hope I get the same chance you did one of these days...
