On the 6th day of my recent Japan trip, I went to Kamakura. Located some 50 kilometers southwest of Tokyo, this small city that's filled with shrines and temples makes for a very pleasant day trip from the Japanese capital -- and I'd go as far as to state that I much preferred visiting it than the apparently more highly thought of Nikko.
Although I only managed to visit five of Kamakura's 65 Buddhist temples and 19 Shinto shrines, I felt I did good for a day -- and enjoyed my day out there so much that I consider it to be one of the high points of my recent Japan vacation.
For the record, the five holy places I managed to go to in that former de facto capital of Japan were the "big three" Kamakura sites of the Hase Kannon Temple (AKA Hasedera), Hachimangu Shrine (AKA Tsurugaoka Hachimangu) and the Kotokuin Temple area that is home to the Daibatsu (i.e., the Great Buddha of Kamakura -- which originally was located inside a temple hall but now is open to the elements, having withstood typhoons and a tsunami even when the temple buildings didn't), and -- via a hiking trail -- a couple of small but interesting and more out-of-the-way Shinto shrines in the Sasuki Inari Jinja and Zeniarai Benten Shrine.
More than incidentally, I don't think it's coincidence that all the sacred places I visited were located on relatively high ground (cf this Photo Hunt entry's top most photo taken in the grounds of the Hase Kannon Temple) and also often required going up a number of steps to get to their main areas (as can be seen in the middle photo taken at Hachimangu Shrine). Perhaps it's thought that one will be more likely to have high minded thoughts when one is up in elevated spaces? Alternatively, it often felt like one was being made to feel some strain and sacrifice while making one's pilgrimage to those sacred places. Alternatively put: no (physical) pain, no (spiritual) gain! ;D
