This year in conjunction of Tokyo Marathon 2012, a BE@RBRICK had released. With the good response it will release the Tokyo Marathon 2013 BE@RBRICK too. The design is posted in the Tokyo Marathon 2012 Facebook Fans Page. The design is similar with this year but the color is different. The front surface in silver instead of black for this year. Based on the picture the behind seem like a light blue to white transparent.
More information will be posted in December through the fans page.
