3.1.3 Region C – Northeast Japan
Tertiary Mountains and Hills and Volcanoes and Volcanic Landforms are the main physiotope
classes, consisting of 30% and 22% respectively, followed by Quaternary Plains with Volcanic
Ash Soil, Quaternary Plains, Mesozoic Granite Mountains and lastly Plutonic and Metamorphic
Mountains (Fig. 2a). This region is characterized by the presence of an isolated Quaternary
Plain with Volcanic Ash Soil patch at a 14% largest patch index (Fig. 2c). Another peculiarity is
