If you can find your original Windows installation disk you can load support for Japanese language on to it. Unfortunately you still need someone to translate the page for you. I married my translator.

If you send me your email address (by PM) I will forward it to my brother-in-law and he will contact you about buying the taishogoto. As for cost I think you are looking at $200 and up but I'm not really sure about that. Mine is very pretty with a lacquer finish and some nice floral work. But the keys are cheap and the sound could be better. It was a gift though and it's the thought that counts. I love it.
