Any good Japan electronics online stores with international shipping?

I know this sounds like a weird question but does anyone know of a well established electronics store in Japan that provides international shipping??

There is something I want to buy that's only available from amazon.jp not amazon.co.uk but apparently they're unable to ship certain items such as electrical goods.

I'm not sure if this is some kind of legal issue in Japan with regards to exports of goods but it's kind of annoying.
