Field information

Yatsugatake Forest is located in the foothills of the eastern slope of Mount Akadake, the highest peak in the Yatsugatake Mountains. Most areas of the forest are characterized by naturally regenerated secondary forests dominated by oak (Quercus crispula) and Asian black birch (Betula davurica) with Siberian hazel (Corylus heterophylla), and an intermediate moor dominated by alder (Alnus japonica) and Japanese flowering crab (Malus siboldii). Forest areas extended over the Yatsugatke Mountains until the early 20th century. However, land reclamation for farming was undertaken around the area of Yatsugatake Forest since the middle of the 20th century. As a result, the Yatsugatake Forest is recently distinguished as an isolated forest surrounded by farmlands. Kawakami Forest is located on the east side of the Yatsugatake Forest in the western part of the Kanto Mountains. Seventy percent of the area of Kawakami Forest is artificial forest with Japanese larch (Larix kaempferi), and the rest of the forest is similar to the Yatsugatake forest, dominated by oak (Quercus crispula), Asian black birch (Betula davurica) and many maple species. Rare species such as Primrose (Primula sieboldii), Japanese dormouse (Glirulus japonicus) and Japanese Luehdorfia (Luehdorfia puziloi) under conservational protection are observed in the Yatstugatake and/or Kawakami Forests. These forests provide a good background for natural sciences and education for student practice courses (forestry, plant pathological mycology and soil science). In addition, undergraduate and graduate student research projects are conducted in both forests during the field-work season. Monitoring for long-term ecological research focusing on regeneration dynamics, matter flow and the economy of the forest ecosystem is carried out in permanent plots of both forests. Another research subject is the population ecology of the Japanese dormouse. Since 2004, boardwalks in the Yatsugatake Forest provide easy access to the the Yatsugatake Forest for field practices and research activities.


The main bilding of the Yatsugatake Forest has a control office, a lecture room and four laboratories. A dormitory can accommodate 36 guests.
