Mirrored up on Seibertron.com are the 8 First Edition Japanese TFPrime toys.

The main differences to the US First Edition figures are:
- Deluxes are packaged in Robot mode (US versions are in vehicle mode)
- no 2-pack in Japan (Megatron is released on its own as a regular Deluxe)
- no 2-pack/Deluxe Optimus in Japan, only the Voyager version.
- the Decepticon Vehicon released in Japan (may yet be released by Hasbro, but time is running out before Wave 1 of the main TFPrime line is released in a couple months)
- there was supposed to be some differing paint/colour apps to the US versions (but I can't see any)
- Probably no Bumblebee Roleplay blaster in the JP First Edition series.
