Displaying the Japanese language

Does anyone know how I would go about enabling my computer to display Japanese writing properly? Do I have to buy something, or does the solution just require a little bit of tinkering with settings and stuff?

Any help would be very appreciated.

I'm not exactly sure.

Thanks a bunch, Samuraid. Turns out that's the exact thing I needed. Problem solved!
