We are staying in Yokohama in January 2014 for 12 nights. I have a list of all the attractions in Yokohama we are interested in but think we will have a few days spare. Can anyone suggest a day trip from Yokohama that we could do? I have info on Nikko and thought this would be good. I am also interested in Mt Fuji. I am interested in any suggestions that may be dfferent. We dont usually do guided tours we like to go at our own pace and I research the area and plan how to get there and what to see. We love history and museums.
