As other figures are mainly the same as Hasbro version, DA03 Optimus Prime Mech Tech Trailer (Voyage Class) is different from the USA counterpart.
For the Japanese version, Optimus Prime is confirmed to come with a trailer. Also the Mech Tech weapon is different as it can turn the fusion canon to a battle blade. Also Takara has omitted the two huge "tanks" beside the (Hasbro version) Optimus Prime's alternate mode or at the back of Prime's robot mode.
Other different such as no transparent panels that especially visible in truck mode.

The first wave Takara DOTM figures are expected to hit Japanese retails on 14th May 2011.
