If you have Windows you don't need to download or buy anything. You just need to turn on the right settings. Someone did it for me, so I'm not entirely sure how to do it, but MMM made a post with a link of how to set it up once in another thread. You could either search for that post or do a google search on how to set up Japanese with your computer.

By the way, you might be able to do it with a Mac too without downloading or buying, but I don't own one, so I'm not sure.

Good luck!
