kewaizaka Pass, located approximately 1.4 km south-west of Tsurugaoka Hachimangu Shrine, is a “kiridoshi” pass that was built to open a route from Ogigayatsu leading to Kanto region. The extant part of the pass, extending over a length of approximately 0.5 km, was constructed by scraping off one side of the slope. In addition, there remains vestiges left by acts of scraping off the mountain on a large scale and many “yagura” caves along the “kiridoshi” pass.
