As a result of creating the distribution map of many Meisho-Zue published at the Edo period, it turned out that the most overlaps with "Miyako Meisho-Zue", and it became clear that the many were adopted as the "Kyoto Minzoku-Shi" published by Showa-period.Since much wells and spring-water existed in the Kyoto city area of the Edo period, as a result of restoring water environment based on it, it became clear that much wells and spring-water existed to Nijo Castle at the westernmost end from near Gosho in the Kyoto city area of those days, and near Kyoto Station. Since well-boaring technology of those days existed sprin-gwater also in that it was about 5-10m at most, and the southwest of the city area when it took into consideration that Kyoto basin was formed with grit(Samegai-well etc.), even if it disregards change of geographical feature, It became clear that the groundwater level existed near bottom of ground surface 1-5m.The boundary line in Rakuchu which capital people in those d … More ays recognized, and besides Rakugai was able to become clear from the analysis result of "Miyako Meisui Mikurabe-Sumo" found out in the research process, and this was able to be presumed to express the boundary line of the figure outside"Rakuchu Rakugai-Zu"also used as a national treasure in detail.Moreover, from existing spring-water and the water analysis result of the well, as one of the methods for presuming catchment are, oxygen and the hydrogen stable isotoperatio of rain were measured, and the method of comparing with the isotopic ratio of groundwater in a basin is effective, and it conducted the detailed investigation.Rain extraction equipment was installed in three points of northern part mountain land(Kibune area) from Kyoto basin for one year from September, 2009 to August, 2010, rain was extracted every two months, and the isotopic ratio was measured.The corresponding object advanced effects of the rain of the result of the isotopic ratio of rain to this research area were-0.7‰/100m(r^2=0.819) in-0.17‰/100m(r^2=0.981), andδD atδ18^O.When synthetically thought from the analysis result of silica, it was checked that it is in a state almost like the groundwater considered to be the Kamogawa-river origin of Kyoto basin has almost constant water quality regardless of the existing depth(5-100 m), and a bamboo basket.It became clear that it is what is depended on the feature of such groundwater that brewing, tofu, soy milk skin, etc. which still used good groundwater in the city area can be manufactured.
