I was not sure what is the Chamorro Dance before, but I was very amazed by their dances and songs and just checked on the internet although it was not easy to find good articles about it...(very few articles mentioning precisely about the Chamorro Dance)... Anyway, I found that the Chamorro Dance is really like Guam, where many cultures are mixed and develop another culture based on Chamorro, I think. Here is an article about the Chamorro Dance which I wrote in Japanese for the Japanese tourists. http://tokuhain.arukikata.co.jp/guam/2012/02/post_403.html
