Shizuoka City acts the role of tea-market that controls the tea-industrial area of Shizuoka Pref., which produces 65% (about 60, 000, 000 pounds) of the output of Japanese tea. The writer discussed the relation of this market to its market region by the investigation through the process of their deve-lopement. The main subjects are summarized as follows:
1. The transaction of tea in Shizuoka commenced in the early days of 17 century. Through the Tokugawa era, it was carried on between the tea-farmers in the Abe and Warashina basin and the tea gild in Sumpu (the old name of Shizuoka city in Tokugawa era), that had the privilege of collecting all the tea produced by farmers. For this reason, Sumpu was the privileged tea-market to its hinterland of that time. This feudal com-mercial relation was broken down by the commencement of tea export at 1858 and the Meiji Restoration.
2. By the influence of export, the tea gardens was increased rapidly in area in different parts of Shizuoka Pref., and about 1880, tea-markets came into existence in the towns along the railway and in the ports. The tea, which was collected at these tea-markets, was supplied to the tea-export-market in Yokohama. By the combination with their surrounding regions, each tea-market had formed an independent tea-industrial region, and they had been united by the export-market in Yokohama. That was the tea-industrial organization in Shizuoka. Pref, at that time (Fig. 2). Shizuoka tea-market had been one of those local markets under such organization, but it had had the largest market region, and had collected about 8, 000, 000 pounds, equivalent to 40% of the output of tea in Shizuoka Pref, about 1900.
3. About 1905, the export-market moved from Yokohaiiia to Shizuoka. For this reason, the latter became the unifying center in the tea-industrial organization, and all the tea-markets in Shizuoka Pref. became the entrepot-markets for the export-market in Shizuoka.
4. After the World War I, tea-making was mechanised, and transporta-tion. made a remarkable progress. By the influences of these changes of conditions, the transaction in the entrep5t-markets AN-as decreased, and the tendency that the tea-maker sell their tea directly to Shizuoka without possing through the entrepot-markets, arose. On the other hand, during the same time, the importance of export-market to the entrepot-markets was diminished, because of the decrease of export. Thus, the latter have enlarged their home-market or home-debouche, and their independent market functions have been raised. These tendencies have become more remarkable after the World War II.
5. Thus, at the present time, the tea market in Shizuoka directly com-bines with his market-region, which covers all the tea industrial regions in Shizuoka Pref., and indirectly with it through the entrepôt-markets above mentioned.
It is the existence of the export-market of tea in Shizuoka City that maintains the tea-industry organization, though it is modified by changes in the environment of tea-industry as exemplified by Ila and IIb in Fig. 2.

Toinvestigate areal differentiation of agricultural regions, various distribution maps were constructed and the results of the agricultural census of 1947 were taken into consideration. Between the upland field section (β) on one hand the upland field section (α) and the paddy field section (ρ) on the other, remarkable areal contrasts were observed as follows:
Ratio of tobacco area to area of all crops:
β section: 0 per cent, no tobacco except in a few enumeration districts.
α section: generally more than 5 per cent; several districts exceed 10 per cent.
ρ section: some peripheral districts range between 5 and 10per cent; some central ones range between 1 and 5 per cent.
Ratio of mulberry area to area of all crops:
β section : over 5 per cent except in southern districts where values less than 2 per cent occur.
α and p section: under 1 per cent with few exceptions.
Ratio of mulberry-growing farms to all farms:
β section: over 20 per cent except for southern districts.
α and p section: under 10 per cent in general.
Average mulberry area per mulberry-growing fauns:
β section: over 3 tanbu (1 tanbu=0.25 acre) except in southern districts.
α and p section: generally less than 2 tanbu.
Ratio of farms engaged in sericulture to all farms:
β section: except for southern districts, generally more than 20per cent.
α and p section: generally under 5 per cent.
Ratio of corn area to area of all crops:
β section: more than 4 per cent with the exception of a few districts.
α and p section : under 4 per cent in general.
Ratio of corn growing farms to all farms:
No remarkable contrast exists: corn is grown by almost every farm as a subsistence crop.
Average corn area per growing farm:
β section: over 0.8 tanbu except southeastern districts.
α and p section: generally less than 0.8 tanbu.
As stated above, the upland field section (β), except for the southern dis-tricts, is characterized as a region with sericulture and corn growing, but almost without tobacco, thus clearly distinguished from the other two sections in which tobacco is planted as a staple crop, sericulture is almost lacking, and corn is also insignificant. Sericulture and tabacco growing are two branches of agricultural operation, which usually stand in contradiction because: (1) Both require a considerable amount of labor at about the same season of the year, resulting in extreme labor concentration if they are planted side by side on the same farm. (2) Mulberry leaves grown in the nieghbourhood of tabacco field are believed to be harmful to silkworms. Moreover, because tabacco-planting, now under the control of the Public Monopoly Bureau, is usually permitted each year to the former growers in preference to new applicants, chances for its spreading into new areas are strictly limited. Accord-ingly, even in 1947 when sericulture was in a depression, the β section re-mained as the sericulture region with no tabacco growing.
Corn in the a section is mostly white dent corn, its seed being exported to Hokkido, where large amounts are required for livestock as ensilage, but where summers are too short to mature its seed properly. In the β section, where the leading sources of cash income such as tabacco in the a and paddy rice in the p section are lacking, dent corn is planted as an auxiliary cash crop utilizing more or less extensive dry fields especially when sericultrue is not profitable. In 1947, dent corn and sericulture contended with each other for fourth and fifth place as sources of cash income next to paddy rice, wheat and sweet-potatoes. In the southern part of the a section, however, where the average area of paddy field per farm is comparatively large and that of dry field small, the corn area per farm remains below that of the main division mentioned above.

In Marugame City, there are two districts of uchiwa production, one along the railway line and the other in the southern part of the city.. This industry is carried on by small-scale factories, wholesale stores, and traders with characteristics of wholesale dealers; the upper part of the industry is under the financial control of Tokyo and Osaka' wholesalers. There is a tendency for the upper part of the industry to be stagnant whilethe lower part is in a ruined and centrifugal condition. The theory of location of industry by Alfred Weber does not rule the industry. The most fundamental locational factor relates to the economic advantages of the area while other factors are the natural social environments. These factors act upon one another to establish the location of the industry. Movement of the production area is the most interesting problem connected with the theory of location,

In this paper the writer describes the torographic features of lacustrine terraces around Lake Inawashiro. The Lake is situated at the southern foot of Mt. Bandai, a famous volcano in Japan. A river flowing over a mud-flow district is the northwestern outlet of the lake.
According to the writers observations, many terraces consisting of “Paleo-Lake Inawashiro beds”, accumulations of later diluvium or early alluvium, are found along the rivers. These terraces containing diatom. fossils which are only found along lake shores. The distribution of these lacustrine terraces indicates, therefore, that the level of the lake were higher than at, present. The maximum. height appears to have been 535 meters above sea level while the present lake level is 514 meters.
This inferred heigit of the level of Paleo-Lake Inawashiro suggests that the lake was made by the damming action of two volcanoes, Mt. Bandai and Mt. Nekoma, and after that the lake water flowed down to the Aizu Basin fromn tine lowest part of Paleo-Lake Inawashiro. That part is Onohara which is composed of the mud-flow “Okinajima-oshidashi”; this mud-flow was not formed by the volcanic activity which formd the present cones of the two volcanos. The general altitude of Onohara, which the writer got by measuring summit levels, is 540 meters above sea level. That altitude generall ycoinci-des with the heights of the lacustrine terraces around the lake.
The existence of many drowned valleys on the bottom of the lake, the charaeter of knick points on the river beds of inflowing rivers which were ex, ased by the lowering of the lake level, and the distribution of earthenwares articles of pre-historic age are further evidences used by the writer.
