If you prefer to use ATOK (the most appreciated IME by Japanese users), the monthly fixed-charge service is reasonable. You can use the same features as the standard & latest version of ATOK, and the monthly charge is just 300 yen. Subscription and cancellation is monthly basis. It works on Japanese version of Windows.
