As I explained on FB, the Revell kits in Japan, are from the old license under Lucas Films, and are just left overs from that license.
You can't expect the re-sellers like HLJ just to stop selling what they have in inventory. If they can't sell it in Japan, they aren't going to sell any back to NA, as the difference in price and shipping won't make it worth it, so they will be allowed to sell out what they have left, but once they are gone, that is it.
Everyone is so quick to blame Revell for this.
Here is the way I look at it. Revell has had the NA and European license for all things Star Wars for about a decade (maybe longer, but at least that long), and it was issued all that time under Lucas Films. Fine Molds also had a license from Lucas Films to build and sell kits in the Japanese/Asian market, and no one from either Revell, Fine Molds, or Lucas Films gave a rat's a$$ if Fine Molds sold their product in NA/Europe, or Revell sold their product in the Asian market.
So why the change? The only thing that has changed is the company in Japan that now has the license for Star Wars, and the big gorilla called Disney that now owns all things Star Wars.
Doesn't take a math guru to put 2+2 together and realize that up until Disney bought Lucas, no one cared who's kits were sold where. Wasn't until they got their hands on them, and issued new licenses that the proverbial crap hit the fan.
Mickey needs a spankin'!!
