Importing games from Japan is a little bit easier now, especially if you've been wanting to use Amazon Japan for purchases. NeoGAF users recently stumbled upon the new option for international shipping, and a few further tests confirmed how simple it is. It only applies to games that Amazon sells directly, but that's plenty.
Anyone who wants to buy a game for themselves can just switch the site to English with the handy 'in English' button at the top, which translates most of the relevant information.
You can browse Amazon Japan's video games section here. You'll also need to start a new account for Amazon Japan if you don't already have one.
