Yes a Japanese web page translator does indeed exist! Go to
www.languageforce.com & view their products. I can tell you that I first
got the Universal Translator from them to help me with my language
studies, it translates 33 languages, including Japanese. However you
have to view each of the products & be very careful about what you buy,
because they all do different things. If you want to translate Japanese
web pages, you must get the UT Stargate package. Not only does it
translate Japanese web pages, but also several other languages including
Chinese! It also tranlates E-Mail, & allows you to participate in
foreign language chat rooms! Its around $189.00 & comes with a headset.
