Mountain Hangetsuyama (半月山, also pronounced as Hangetsusan) is a mountain at the southeastern corner of Lake Chuzenji.
Hiking trails lead up to the top of the mountain. Near the summit there is an observation deck with great views of the Okunikko region including Lake Chuzenji and Mount Nantai. The Hangetsuyama Observatory is known as one of Nikko’s most spectacular spots, with a panoramic view of Hatchodejima. The scenery from the drive route on the way is also spectacular.
For those who want to enjoy hiking, we also recommend the walking path from the Hangetsuyama Daiichi Parking Lot on the way. The altitude of Mt. Hangetsu is 1,753 meters. It takes about 30 minutes on foot from the Hangetsuyama Daiichi Parking Lot to the summit, and about 1 hour from the summit to Tanukikubo on the shores of Lake Chuzenji, so you can fully enjoy the nature of Oku-Nikko even in a short time. It is a popular hiking trail that you can do.
