It could be a TakaraTOMY Mall exclusive for Japan, similar to how say MP Star Sabre was a Toys R Us exclusive here. This isn't the first time though. I have 2 versions of Energon Energon Strongarm - the regular store release that I bought here, and the limited store exclusive from Japan. Do you know what the difference is? Absolutely nothing. Aside from the fact that my exclusive Takara version is missing an arm because that's how I got it (it was a freebie ). Or heck, back in 1985 Takara released Reflector as a regular mass store release set, but a year later Hasbro released them as a limited mail-away exclusive. There's no difference between the toys aside from packaging.
