HMV uses what most jp. stores use, EMS and that's pretty fast, I'd say you'll get your item in less than a week for sure. Amazon.jp ships whatever they have in stock, so if you have more than one item ordered, they might run out of first pressing editions before your order ships. HMV allocates the item to your order, so if you preorder soon enough, you'll definetly get first pressing regardless of when your order ships. Also you can contact their customer support to confirm you'll be getting the first pressing (CDJ displays if you have the 1st press ordered, but they're quite a bit more expensive).
