Is dancing big in Japan?

Question:

Most internet stars get famous in Japan for dancing so is that a big thing over there?
Also on NicoNicoDouga (Japanese YouTube sort of) What could i do to get the Japanese public interested? Like Beckii Cruel :) I wanna become a Japanese idol too
If you think the second question is stupid just simply don't answer because i don't care what you think
Anything is possible :)

Answer:

some types of dancing are popular here, but internet stars aren't famous at all over here.

There have been a few break dancers and Jpop idol dancers on a program called Star Draft which finds young talent (sort of) but, it's really not that big. Though I do see people practicing in the shopping area downtime at night sometimes.

There are other sorts of dances as well, though. My fiancee does Yosakoi, which is a semi-traditional Japanese dance (traditional mixed with some modern stuff) and is popular at festivals. There is also a famous festival near my city called Owara Kaze no Bon, where there is a specific, very beautiful, traditional dance done. These aren't the types of dance you're talking about, but they're popular-ish here.
