There’s not much on his page yet except for his profile picture and his biography. The only thing I see of interest so far is Tsunku tweeted two photos of the H!P girls practicing for their upcoming summer concert. Since his facebook is connected to his twitter and blog his Facebook is a much easier way to stay up to date with things. Also Facebook is one of the most popular social sites so it’s good promotion for himself.
Hopefully other UFA artists follow the example and more of them join Facebook.
