Nokogiri-yama is a mountain forming the border of Kyonan-machi in Awa-gun and Kimitsu City, Chiba Pref. The mountain is 329 m above sea level. It is a part of Boso Kyuryo (hills) and Minami-Boso Quasi-National Park. The rocky cliffs are composed of tuff, which was called Boshu-stone and had been quarried as building material since the Edo period. The stone was used for the construction of many buildings in Tokyo including Waseda University and Yasukuni Shrine, but quarrying is shut down at the present day. As the quarried cliffs were shaped like the teeth of saw, people began to call it Nokogiri-yama (saw-mountain). The original name is Mt. Kenkon. The access to the top is easy by taking the ropeway from the foot of the mountain. You can command a panoramic view including Mt. Fuji and the towns of Yokohama beyond Tokyo Bay.
