Out in January in Japan is a licensed model kit of the Bumblebee movie Bumblebee... for 3780yen.

Apparently Kingdom Megatron (t-rex) and Blackarachnia will be released in Japan in April, and some official images have been released.

Also for April are three of the 1986 Movie Studio Series toys, which will be labelled in Japan with regular Studio Series numbers (not the SS86 numbers that Hasbro are using).
Jazz is SS-59, Hotrod is SS-60, Kup is SS-61.

Meanwhile, there are three more TakaraTomyMall exclusives for April, with ER EX-24 Thrust, ER EX-23 Runabout and KD EX-02 Vertebreak.
