i have been asked about an easy way to get a Japanese keyboard. looking around most pages will take you to a full Japanese page when you change the language. This is not helpful when looking to start learning Japanese and want a keyboard that has the Hiragana on them.
By far the easiest way to get a keyboard is from Apple. On the page that allows you to add to the cart, you can select what language you would like the keyboard to be in. It is that simple, select your language and add to cart. you will then be taken to the check out and your keyboard will be on its way.
here is a link to a wireless keyboard from Apple that you can order.
