Past environmental information has been extracted from terrestrial laminated carbonates such as speleothems in caves and tufa deposits on karst surface stream beds in limestone areas of Iwate, Fukushima, Yamaguchi, Fukuoka, Nagasaki, Kagoshima and Okinawa as follows: i) The historical anthropogenic vegetation change from forest to grassland and/or fields was recorded everywhere in Japan. ii) It is clarified that long-range transport of acid depositions from the AsianContinent has been clearly observed in the stalagmites and tufa deposits. In the eastern area of Akiyoshi-dai Plateau, the possibility of reduction of the biomass by acid rain or leaching of the magnesium ions from the soil was suggested, mainly due to the smelting of copper ores from the sulfidezone. iii) The effects of large scale tunamis wereexamined with respect to the stalagmites from Iwate and Ishigakijima Is. iv) The records were in good agreement with those partially extracted from ancient documents, ancient picture maps and topographical maps. v) Lectures on the historical recordson Akiyoshi-dai Plateau were held in Mine City, Yamaguchi, in March, 2013.

从岩手、福岛、山口、福冈、长崎、鹿儿岛和冲绳石灰岩地区的岩溶地表河床上的洞穴沉积物和石灰华沉积物等陆地层状碳酸盐岩中提取了过去的环境信息，具体如下：i）在日本各地都记录了从森林到草地和/或田野的历史人为植被变化。（2）阐明了石笋和石灰华沉积物中明显存在来自亚洲大陆的酸性沉积物的远距离迁移。在秋吉台高原东部地区，酸雨或土壤中镁离子的淋溶可能导致生物量的减少，主要原因是硫化带中铜矿的冶炼。（3）以岩手和石垣岛的石笋为研究对象，考察了大型金枪鱼对石笋的影响。（4）这些记录与部分从古代文献、古代图画地图和地形图中提取的记录吻合较好。2013年3月，在山口县矿山市举办了关于秋吉台高原历史记载的讲座。
