About Inabayama and Miyajimakyo Prefectural Park
Inabayama and Miyajimakyo Prefectural Park is a prefectural park spanning Nanto City and Oyabe City in Toyama Prefecture. It was designated as a prefectural park in Toyama in 1955 (Showa 30). The park covers a total area of approximately 1,200 hectares, with Inabayama mountain at an elevation of 346 meters at its center, surrounded by the scenic gorge of Miyajimakyo.
Characteristics of the Park
The greatest characteristic of Inabayama and Miyajimakyo Prefectural Park is that it is an easily accessible satoyama (foothill village landscape) while maintaining a rich natural environment. Although the elevation is not particularly high, the varied topography and diverse vegetation provide visitors with beautiful scenery throughout the four seasons.
The park is covered with deciduous broadleaf forests such as Japanese beech and Mongolian oak, offering different views with each season: fresh green in spring, deep green in summer, autumn leaves in fall, and snowy landscapes in winter. Along the stream, moss-covered rocks and clear flowing water create a healing space full of negative ions.
The Appeal and Climbing Routes of Inabayama
About Inabayama
Inabayama, with an elevation of 346 meters, is not a high mountain, but the view from the summit is excellent, and on clear days, you can see the Tateyama and Hakusan mountain ranges. It is also popular as an ideal viewpoint for overlooking the unique landscape of the Tonami Plain, known as a scattered settlement village.
There are various theories about the origin of the mountain’s name, but it is said to be named after the area’s former thriving rice cultivation or the mountain’s shape resembling stacked rice.
