The four ridges are Higashikama (東鎌), Yarihotaka (槍穂高), Nishikama (西鎌) and Kitakama (北鎌) to the east, south, west and north, respectively.

The four valleys are Yarizawa (槍沢), Hidazawa or Yaridaira (飛騨沢 or 槍平), Senjōzawa (千丈沢) and Tenjōzawa (天丈沢) to the southeast, southwest, northwest and northeast, respectively.

In the autumn of 2005, a new mountain trail was constructed going up from Hidarimata Valley (左俣谷 Hidarimata-dani) to Mount Okumaru (奥丸山 Okumaru-yama).

This made it possible to reach Yari-ga-take walking from Shinhodaka onsen upstream along the Hidarimata Valley following the mountain ridge of Mount Okumaru.

Being situated in the Japanese Alps, several prominent mountains can be reached from Mount Yari, among them: Sugoroku-dake (双六岳), Nishi-dake (西岳), Ōgui-dake (大喰岳), Naka-dake (中岳), Minami-dake (南岳), Okumaru-yama (奥丸山).
