I have a MacBook OS X version 10.6.2, and I ordered my MacBook with a Japanese keyboard. The only problem is it doesn't type in Japanese.

Sure I can type Japanese by switching the language input at the top right, but it types using the English letters to make kana. It doesn't use the kana on the keys...

Does anyone know how I can switch the input of the keyboard itself so that it doesn't type in English letters but in the kana printed on the keys?
