In the case of Kinokuniya, as direct imports they would have been slapped with a truckload of import duties, taxes, levies etc. which jacks the prices up. That's why a lot of import stores are so expensive.
Ghost Starscream shouldn't have been an import though -- that would have been distributed by Hasbro Australia and thus exempt from the kinds of tax stuff that importers have to pay. I can't think of any good reason for TRU to charge such a ridiculous price for Ghost Starscream. After all, Hasbro AU previously distributed Masterpiece Ultra Magnus and MP Convoy w/ trailer to Target who sold them at reasonable prices.
And it's not the first time we've seen TRU do this. They'll happily let expensive toys shelf warm for years. Look at how long Supreme Cheetor self warmed for (although that wasn't necessarily "overpriced" they sure didn't bother marking it down after ages of shelfwarming). Then there was G1 coloured movie Jazz... what a rip. TRU seem to have a habit of overcharging for exclusive toys.
