Ikawa University Forest is located on eastern part of the Akaishi Mountains, Central Honshu. Ikawa University Forest covers the upper stream of the Higashigouchi River, a tributary of the Ohi River, and forms a 1700 ha basin. The lowest elevation in the Ikawa University Forest is at the south end (900 m asl), whereas the highest elevation is the peak of Mt. Aonagi (2406 m asl) at the northwest end. Vegetation types in the Ikawa University Forest change with the elevation. Broad-leaved deciduous forest mainly composed mainly of Quercus cripula and maple trees are distributed in the low-altitude areas, while subalpine conifer forest (e.g., Abies mariesii) are distributed in the higher-altitude areas (over 2000 m asl). Ikawa University Forest is a suitable site for studies and research on natural vegetation and wild animals because of extensive secondary forests (1350 ha). Median Tectonic Line and Itoigawa-Shizuoka Tectonic Line, the largest tectonic lines in Japan, cross at the northern tip of the Akaishi Mountains. Therefore bedrock fractured by active tectonics is significantly weak. Several large landslide (> 5 ha) amd multiple shallow landslides in the Ikawa University Forest supply large amounts of sediment. Debris flow also frequently occurs in the rivers and tributaries. Therefore, many field studies and observations on the geomorphology of high mountains have been conducted in the Ikawa University Forest.
The main bilding, a garage, Automated Meteorological Data Acquisition System (AMeDAS), and an outdoor house at Mutake. The main bilding is comprised of a control office, a lecture room, and a dormitory with a dining room, a kitchen, bed rooms and both rooms. A dormitory can accommodate about 28 guests.
Orthonized-color aerophotographs（resolution: 40cm), monochrome aerophotographs, 1m mesh DEM, weather stations（six sites), a wheel loader, dry oven, river flow meters (two sites) and others.
