Where are you living? Is it the UK? Because if so, you'll need a TV that can do 60hz. Every TV on sale (except second hand ones) will be of 60hz.
If it's the US, then I'm not familiar with watching Japanese formats on a US television.
Oh, and I'm not sure, but I think there might be a way to set the language of the Wii, possibly to English. Should be in the Wii menu (bottom left hand corner). Try the options one at a time changing them until the desired happens. (I know, it's a clumsy way of doing it, but you should be fine).
