You surely know that Japan is crazy for Powerpop in any direction, they just LOVE it, the Bubblegum or 70ties blended, the rocking and rolling type, the kind of that make your hearts explode (sic!).... and of course there are hundreds of powerpop bands there - and MOST of them are actually pretty good, but few stand out, and THE CHOOSERS are definitely in the Top 3.
