If you ever check out Yamada Denki for iPad and iPhone accessories, the range is quite limited and simple. They generally stock a lot of expensive Softbank accessories, so I have been on the hunt for some interesting websites in Japan that stock some decent ones.

The AppBank Store shop stocks a whole range of interesting products and lots more than you will typically find in your department stores here in Tokyo.

Some of the products that have tempted me:
Ipad venture Case-Mate
Ipad 2 Smartcover
