You won't see the keyboard change like you did in XI but it's there, try ALT+~ to see if that switches input to Japanese, if not the language might be on English so try ALT+SHIFT to switch first and type, if still not godo, try ALT+~ after this. Wish there was a display icon showing the language status.

I'm on English Windows 7 with Japanese IME, and playing FFXIV in Japanese on a US version CE box.
If you have Windows 8, you can use the "Windows Key + Space" in order to switch between keyboard settings. You just need to make sure that you have the Japanese Language added to your list of available Languages (which you can find by pressing the Start key and search for "Language" in the start menu).

Hope this helps! (^_^ )
