Tateyama Mountains(Highest Peak Mt. O-nanji-yama)

Tateyama Mountains is representative of the mountains in Chubu-Sangaku National Park and is located in the northern part of the Northern Japan Alps.  Interestingly, a mountain named Mt. Tate-yama does not exist.  In general, three mountains, Mt. O’yama (3,003M), Mt. O-nanji-yama (3,015M), and Mt. Fujino-oritate, are called Tateyama mountains.  The main peak is Mt. O’yama and the highest peak is Mt. O-nanji-yama.

 

Tateyama Mountains, known from the past as a place for mountain worship, is also known as one of Japan’s three holy mountains with Mt. Fuji-yama, Mt. Haku-san.

O’yama Shrine stands at the peak of Mt. O’yama and in summer hiking season, a prayer service is held by a Shinto priest.

Tateyama Mountains keep people away for more than half a year, even then, many hikers visit the mountain to enjoy the wide variety of alpine plants in season.  There is also a good chance that one will encounter ptarmigan in this area.

Tateyama Mountains : Elevation 3,015m (Highest Peak Mt. O-nanji-yama)

The typical route to Mt. O’yama and Mt. O-naji-yama starts from Murodo, passing by Ichi-nokoshi to the summits.  Most hikers, however, take the trail back when they reach Mt. O’yama and do not continue to hike to Mt. O-naji-yama.  They visit the mountain out of religious faith and do not seem interested in the highest peak of Tateyama mountains.  A trail from Mt. O’yama to Mt. O-naji-yama is a graveled ridgeline but does not include a hazardous zone.  The hike on this path gives you a rare experience of a 3,000m altitude ridge walk so it is highly recommended.

 

From Murodo, there is a trail which passes Mt. Ryuo-dake and reaches Mt. O’yama by Ichi-nokoshi or another trail that climbs up from Raicho-sawa to Raicho-saka, then reaches a ridgeline by Bessan-nokkoshi to Mt. O’yama.

For the beginners, a round trip from Murodo ~ Ichi-nokoshi ~ Mt. O’yama ~ Mt. O-naji is recommended.

Also, many hikers enjoy the route from Mt. O-naji-yama ~ Fujino-oritate ~ Bessan ~Bessan-nokkoshi ~ Raicho-sawa ~ Murodo.
