At the small land, like in Japan, it is not adequate to explain the relation between land and agricultural management studying only the relation between nature and agricultual crop. Important is the process of development in which, nature turns to the agricultural land or forestland.
About preservatiou of agricultural land the important problems are how to protest the agricultural land from flood, droght or soil erosion. They consider the natural and cultural reason of outbreak of damage and they are going to clearify the conditions hindering from restoration of field & establish the plan. At the problem of land improvement they study the irrigation of field, equipment to adjust water temperataue and drainage.
Altitude limit of the rice field is higher in southwestern and central Japan and lower in northeastern Japan. This is caused by climatical, technical or economical-social reason. Geographic study of water preservation tells us that water is well reserved in the rice field of independent farmers while bad in that of tenant farmers. The tenant farmers have few found and the farm would not become their holding even if they cultivate, so they could not deal with water-leaking or adjustment of floor. Even if they made “Nurume” temperature had not been raised effectively, because it took much time to go and come to their scattered farms, and they could not manage it as the labor power was wanted.

By the “Zenkoku Kojo Tsuran. 1950, ” list of factories in Japan, I recollected all factories by cities, towns and villages. Then I dotted them every community. Therefore the Maps show the regional distribution of industries in Japan.
The facts, observed by this work, are as follows; (1) Industrial distribution have four cores, viz. Tokyo district, Osaka district, Nagoya district and Northern Kyushu district. From these cores the factories expand all around. (2) Many of the big factories situate at the sea coast, while the small ones distribute at the inland districts. And in case of the latter, the industries are chiefly lumbering, agricultural tools, foods, fabrics.
The reason of this fact comes from the abundance of raw materials, lack of capitals, demand of regional makets, and especially the existence of agrarian over-population.

(1) Regarding the administrative unit os the social unit, when we use figures to explain the way of adoptation of population groups to the environment and the way of constitution of environment by the occupation ratio and population density, the arithmetical-progressional difference of the former corresponds with the geometrical-progressional difference of the latter. The secondary and the third industrial population ratio indicates the positive co-relation, while the primary industrial population ratio indicates the negative co-relation. These co-relation come to being successively about two variables and essential grade construction can not be found. We get the almost similar conclusion by the special consideration. The special co-relation at a certain time might constitute approximately im the time system too. So we can suppose the process of urbanization by it.
(2) About administrative unit (especially town) we can recognize the following co-relation: (a) occupation ratio and area (b) occupation ratio and arithmetical population density. About these two items the arithmetical-progressional difference of the former corespond with the geometrical-progressional difference of the latter. At the case of (a) the secondary and the third industrial population ratio have the negative co-relation and at the case of (b) the primary the positive co-lelation. (c) Between the arithmetical population density and the area variable arithmetical-progressional difference coresponds with the geometrical progressional difference of the other variable which indicates the inversely proportional relation the rule of the above mentioned relation seems to show the essential character of adaptation of the human rase to the environment.

Three are some back mashes at the behind of natural levees on the lower Yoshii. As it was difficult to develop the rice field on the slope at the outside of the nutural levees. Many villages depended upon the field though they were on the river. In Tabarakami mura and Futsukaichi mura the field turned to the rise field at the beginning of Edo era, and even now some villages have only a few rice field. While the back marsh was the most favorable rice field at the beginning of agricultural era. Therefore many old tombs are found at the hill at the behind of back levee and the Jori system was laid down here. The stream starting from the back march led the rice field to develop in the broad area to carry out the Jori system. At the middle age, perhaps, they had one crop fields. Some back marshes which might become the pond easily became it due to the lower river. These Hiokike (pond) and Kita ike (pond) were made. But they were abandoned by drainage and cultivation of back marsh at the beginning of Edo era. The irrigation association showed activity at the rice planting season, especially. The significance of back marsh is varied due to its low temperature or owing to the area and era. The back marsh of the lower Yashii was developped by stagnant water. But now they are suffering from surplus water.
