Mount Takanosu (鷹ノ巣山) is a 1,736m-high mountain in Okutama City, in western Tokyo. It is a popular waypoint on the way to Mount Kumotori, the highest peak in Tokyo. I started the hike at Okutama station (奥多摩駅) in the morning and followed the Ishi Ridge (石尾根; Ishione) through Mount Mutsuishi（六ツ石山; 1,479m）to the summit of Mount Takanosu. There was a great view of Mount Fuji there. I then went down the mountain towards Nippara Valley (日原). There, I hurried to visit the Nippara Cave (日原鍾乳洞), the largest limestone cave in the Kanto region, before taking the bus back to Okutama station.
