“…Although the surface geology is almost uniform, the physical properties of the parent materials vary to some extent depending on the present topographical position. Because the churning movement of the soil materials associated with cryoturbation during the last glacial age was strong in this area (Nogami et al 1980), the depth of the weathered crust on foot slopes or inter-hill depressions is much deeper than that on the rounded tops of hills.…”

“…Tephrochronology suggests their major activity during the LGM (Koiwa 2003;Sawaguchi 2006), but there is no agreement on the environmental conditions when they formed. The wavy forms display a variety of shapes and dimensions, with the largest reaching 2-3 m in (peak-to-peak) am- plitude (Nogami et al 1980). In general, small waves (amplitude <0.6 m) can originate from progressive cryoturbation under non-permafrost (seasonal frost) conditions, whereas larger waves (0.6-2.0 m) occur within the active layer underlain by permafrost (e.g., Huijzer and Isarin 1997).…”

This paper reviews glacial and periglacial geomorphology and associated studies on physical geography and Quaternary geology, undertaken by Japanese researchers during the last three decades. Major progress has been achieved in two aspects. First, overseas fieldwork in a wide range of polar and alpine regions has promoted understanding of present-day glacier and permafrost landforms, processes and sediments. The outcomes have greatly influenced domestic research, improving the interpretation of past glaciation and periglaciation in Japan. Second, Japanese studies have made significant contributions to the international research communities in applying tephrochronology to dating tills and periglacial structures, proposing a distinct feature of glacial advances possibly reflecting climate conditions in eastern Asia, promoting comprehensive monitoring of periglacial processes and understanding periglacial processes in seasonal frost and marginal periglacial conditions.

Conditions for the development of the Pinus pumila zone of Hokkaido, northern Japan

The development of the Pinus pumila zone of Hokkaido, northern J a p a n is discussed on the basis of an examination of the Warmth Index (WI). The Pinus pumila zone is developed on deforested areas in the boreal subalpine belt, and is characterized by strong wind and heavy snow accumulation in winter, and by the presence of rocky fields. It is concluded that in Japan, including Hokkaido, this high mountain zone generally is intrazonal, belonging mainly to the subalpine belt, and that such zones are not common in Europe and North America. Its formation is due mainly to present-day wind, snow and substrate conditions and partly to conditions prevailing during the glacial period.
