As part of an on-going brand of Playstation-related goods for Japan, the Signature Series boasts gamer accessories for the sophisticated and elite, including things like wine glasses and crew neck knitted shirts. More recently though, a Tukimi (black PSP) and Kachofugetsu (white psp) have surfaced as part of the collection. They’re only exclusive to Japan and would weigh in at a hefty $272 US. Perhaps Kotaku could help with the game-related Japanese translation here.

More can be found on the official Japanese Playstation website.
