Haha, ok. Let me try and write out the steps.

1. Click on Start -> Control Panel
2. Click on Clock, Language, and Region
3. Click on, "Change keyboards or other input methods"
4. Click on, "Change keyboards"
5. Click on, "Add..." and scroll down until you see "Japanese (Japan)", click the drop-down list and click on "Keyboard", then check, "Microsoft IME".

Tadaa!
