ID an Asian arcade game?

[Cobra Commander]

I don't know if you guys have ever been to ebaum's world or not, but they have a couple of amazing clips of some people playing video games.
This clip here (http://media.ebaumsworld.com/asianarcade.wmv) shows a game that I have never heard of. Like DDR crossed with Donkey Konga with a hell of alot more buttons. Any idea what this game is called and if it may exist in the US?

Pop'n Music. Another in the line of Konami's bemani games.

Only a single arcade version was released in the US, and I believe it's based on the 1st Japanese release (i.e. maybe a dozen songs at most). Japan has had roughly 15 different arcade releases so far, and a similar number of home releases. The Gameboy Color version of the first game is surprisingly good.

Oh, and that video clip is of Classic 4 being played on Hyper mode, which is nothing compared to some of the more recent hellishness. ;-)
