The official site for Kre-O in Japan has opened. Takara-Tomy have put up a site for their releases of Transformers Kre-O, which kicks off with many of the Battle for Energon series sets (Street Showdown, Battle for Energon, Rotor Rumble, Stealth Bumblebee are all set to be released, along with the series 1 basic Optimus Prime and Bumblebee sets)
The website has pages for each of those sets along with instructions scans. There's not much else to be seen - the sets are largely the same as their US release.
