Does anyone know why this "ships free to anywhere in the world except for Japan"? The Japanese landing page seems to only state that it'll be available soon, though I might've missed something on there as my Japanese isn't that strong yet.

From the text that linked to the Japanese article, there were mentions about certificate, and then a quick googling of the roman words would actually be enough for almost anybody to get the gist of the text.
