On the top left, you can set the Shipping Address (that is unrelated to the shipping address of your amazon account, you can freely change it to any place on the earth).
Just change it to somewhere in Tokyo and it will show up.
But i'd recommend to just buy at e-earphone because they are 1. official and certified, authorized Sony partner (and the biggest one) and 2. the price is lower because Sony gives 10% off on the WM1ZM2 and WM1AM2. e-earphone only shows the 10% off prices when your logged in, but its cheaper + you're suporting a cool company instead of amazon
