Cold Region Geomorphology in Japan

抄録

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.
