We conducted research on historical development, formation processes and characteristic of geomorphology of coastal sand dunes in Japan from the sediment material points of view. Three field sites were surveyed intensively: the Enshu-nada Sand Dune at Shizuoka Prefecture, the Katamachi Sand Dune at Niigata Prefecture and the Tottori Sand Dune at Tottori Prefecture. The width of the coastal dunes along the Enshu-nada increases from 100m to more than 1,200m towards the east from the mouth of the Tenryu River. In contrast, moving away from the mouth of the Tenryu River, the beach width decreases from 260m to 30m. We surveyed size distributions of beach sediments and beach profiles and concluded that grain size distribution of berm deposits had clue to development of coastal dunes. Interaction between wave processes and blown sand ones were discussed. On the other hand, the Katamachi Sand Dune similarly illustrates that moving away from the mouth of the Seki River; size of the coastal sand … More dune increases. Mineral compositional surveys over the drainage basin of the Seki River revealed that longitudinal dunes were developed at c.a. 80,000-50,000y.B.P., triggered by the volcanic activity of the Myoukou Volcano. Historical formative processes of the Katamachi Sand Dune explain dimensional variations of the dune. Formation processes of the Tottori Sand Dune were surveyed with boreholes (named as B5 and B6) and microtremor measurements. With facies, sequence stratigraphy, diatom, pollen, paleo magne and electorical conductivity analyses as well, we are still discussing paleo environmental changes before the formation of the sand dune. In addition, formation processes of the Oigo-Suribachi at the Tottori Sand Dune were surveyed by wind tunnel experiments and proposed its conservational provision. As for countermeasures for meadow overgrowth at the Tottori Sand Dune, we conducted field experiments for vegetation mapagement using sandblasting and seawater spraying and got some valuable results.

我们从沉积物材料的角度研究了日本沿海沙丘的历史发展，形成过程和表征的研究。对三个场地进行了深入的调查：Shimaka县的Enshu-Nada沙丘，Niigata县的Katamachi Sand Dune和Tottori县的Tottori Sand Dune。沿着Enshu-Nada沿线的沿海沙丘的宽度从Tenryu河口向东增加到1,200m以上。相比之下，从Tenryu河的口搬走，海滩宽度从260m降至30m。我们调查了海滩沉积物和海滩概况的规模分布，并得出结论，毛刺矿床的谷物尺寸分布有线索，可以发展沿海沙丘的发展。讨论了波过程与吹砂之间的相互作用。另一方面，卡塔马奇沙丘类似地说明了从Seki河口移开。沿海沙子的大小……更多的沙丘增加了。 Seki河流盆地上的矿物复合调查显示，C.A.开发了纵向沙丘。 80,000-50,000Y.B.P。，由Myukou火山的火山活动触发。卡塔马奇沙丘的历史形成过程解释了沙丘的维度变化。托托里沙丘的形成过程用钻孔（称为B5和B6）和微生物测量值对它们进行了调查。借助设施，序列层学，硅藻，花粉，古磁和电导率分析，我们仍在讨论Sand Dune形成之前的古环境变化。此外，通过风洞实验对托托里沙丘上的Oigo-Suribachi的形成过程进行了调查，并提出了其保管条款。至于托托里沙丘上草地过度生长的对策，我们使用喷砂和海水喷涂进行了田间实验，以进行植被mapage，并获得了一些宝贵的效果。较少的
