Kamakura is one of the most cultural areas of Japan. It has so many interesting temples and shrines. Many are free, the ones that are not are only a few hundred Yen to get in. You get there directly from Tokyo station for about Y700 and it takes about an hour. You can easily spend a half to a full day visiting all the sights. They are each different enough to justify seeing them all. We only visited a few to make it a half day trip, and it was well worth it. Thie was the 4th time I've been to Kamakura.
