Since the first report by Teiichi TOKUDA in 1917, about 300 reports on the sand dune study had been published in Japan until 1973.
Fig. 1 shows the number of the papers published during that period. A rapid increase is seen in 1963, when active researches were stimulated by an excursion organized by the Japanese Geological Collaboration. Chances for publication were given at the symposium in 1966 held by the Japanese Geological Society as well as at the Tottori Symposium in 1970 held by the Association of Japanese Geographers.
In the early days, studies were concerned with the characteristics of the sand dune itself, such as the form of dune, the size of sand grains, and the velocity of sand movements. In the recent years, the primary interest has focused on the earth histories of both sand dune and surrounding regions. The influence of changes of sea level, climate and vegetation upon the formation of the sand dune have also been studied.
