The Japanese version of that tune is fantastic. The lyrics are different, of course, but they're still wonderful and rousing. So is this version by the indie two piece known as Tsuzuri Zukuri. I've never heard of this duo before, and the lead singer, Hiromi Sugai, has a great voice. So thanks to Kotaku Japan for unearthing this!
