It's so frustrating these JP TF toys are available as a preorder at non-JP online stores (USA, HK) as soon as the news breaks but appear on the JP online sites (such as HLJ) much, much later on.
I think it's something to do with the Japanese retailers respecting embargoes TT put on them. HK retailers and BBTS don't seem to respect it. Odd that BBTS doesn't since they respect Hasbro's embargoes.
I have a list of all G1 characters that have been released in CHUG form. You can find it here. Please feel free to let me know if I got anything wrong so I can fix it.
