As this is a chaku uta download only release only those in Japan will be able to buy the song for their cell phones.

I think it is rather nice that they will release this version of the song. One of the big things about going to a concert in Japan is doing all the cheers and hand movements with the rest of the audience. And Johnny's seems to like trying to get the audience to participate like with them having put up videos on Johnny's net to teach dances before so this kind of release seems to be another extension of that.
It is just a pity that it is a Japan only release.
