Looking for mixed onsen (konyoku) in the Nikko area
 

Wife and I will be leaving for Nikko in two days for a little Golden Week vacation, and are interested in trying some new Onsen. We'd like to be able to bathe together, but already have the "private bath" option at our hotel, so are interested in the real, traditional experience of konyoku. We'll be staying in Nikko proper, so preferably something not TOO far out of the way. Anyone with info is most appreciated (particularly station info and directions or links, etc.). Thanks!
