The plastic insert looks to be the Decepticon Minibots, which doesn't belong inside the Autobot box. :(
Regarding the box, it's a generic Collector's Edition Autobot reissue box. You can't identify from the front. But from the back, there should be a sticker on the bottom right side which identifies the Autobot number, hence the Autobot character. Perhaps the name in Japanese as well but I can't read Japanese. Do you mind posting a pic of the back of the box?
Where it gets tricky is when there are several variants of the same character. For example:
04 - Lambor (Sideswipe) & New Year Special Lambor
05 - (Red) Alert & New Year Special Alert
08 - Streak (Anime version) & Streak (silver plate version)
Hope this helps.
