Nothing's coming up just by searching the internet so I assumed they don't have a show like that. But somebody from Japan will probably know better.
I've always wanted to be a fly on the wall when Dai was learning / practicing his hip hop dance for his Swan Lake SP. His Mambo SP also made me imagine how would that look on a dance floor. Explosive, to say at least
Great minds think alike. I was also searching. I found this on Wikipedia but it seems to be an old show.
"The Japanese version is called Shall We Dance? It has the same title as the 1996 movie by the same name, but it has no relation to it beyond the shared name. Due to the fact that there was already a series-special dancing program, and that many cast members from it also appeared in the new program, the Japanese version was confused with a regularly scheduled version of the series-special, rather than its own version of the TV series. This one ran from 8 April 2006, to 17 March 2007 on NTV-4".
I also would have loved to see him learning the choreography. I trained in dance for many years so I think this is why I was drawn to his skating (and perhaps critical of others who the judges deem to be artistic but my trained eye says otherwise). Watching him rehearsing Swan Lake would have been so much fun and very intriguing. Any of his programs would have been so interesting to watch. He truly missed his calling as a dancer but I'm glad for his fans that he took the skating path. It would have been less wear and tear on his body but the world would have missed out on all of those special performances.
