Types of Commercial Warehouses in the Tokai and Hokuriku Area and the Basis of Their Existence

The distribution of warehouses in Japan is highly concentrated in Aichi Pref. and Shizuoka Pref. by comparison with other prefectures. Predominantly stored items of each locality are iron and steel, wheat, beans, other cereals, and tobacco leaves in the Nagoya Port area; food in commercial areas of Nagoya and Shimizu City; textile goods in Ichinomiya City and Fukui City; paper and pulp in Fuji City, and chemicals in Yokkaichi City.The warehouses are grouped into three types: warehouses in producing areas, those in transit areas, and those in consuming areas. Warehouses in Ichinomiya, Fuji and Fukui are those of the producing-area type; those in the Nagoya port area, Tobishima Village, and Tokai City are of the transit-area type; and those in commercial areas in Nagoya are of the consuming-area type, in the main.Factors affecting the location of warehouses in the textile-centered producing areas of Ichinomiya and Fukui lie in the division of labor in the production processes and the seasonality of demand; and those in pulp-and-paper producing Fuji and chemical-producing Yokkaichi lie in stagnant freight trading at harbors, and the existence of the consuming-area warehouses corresponds to consumers' demand in the built-up areas of highly centralized cities.Major conditions affecting the location of a warehouse are: for producing-area warehouses, the producer's development of a stock-reducing plan. Transit-area warehouses are indicated by quantity of goods and intended handling at a harbor. Positional relation to central megalopolises is critical for consuming-area warehouses.

The Trend of Heavy Freight Storing and the Areal Differences of the Demands in Tokai Area

Concerning the distribution of littoral relay warehouses, the warehouses of cement and petroleum products center on Nagoya Port, though rather dispersed locations can also be found. On the contrary there is a remarkable concentration of steel warehouses at Nagoya Port. This occurs because steel, which is heavy and solid, with a diversity of products, can be loaded more efficiently, and because of the ever-present demand at that location.The shipping areas of cement for littoral relay warehouses center in the western area of Japan where there is a surplus of production. Steel warehouses cross all of Japan. This is affected by the varieties of products, locations and production capacities of steel mills. Petroleum product warehouses range from the Kanto area to the Kansai area; mainly centering in the Tokai area. Because few differences are found among products of oil refineries, receiving from the nearby vicinity is promoted.Though cement and petroleum products are marketed most in Aichi Pref., these also are marketed comparatively well in Gifu Pref. and Mie Pref., while steel is marketed overwhelmingly in Aichi Pref. This high demand for steel comes from development of automobile industry in Aichi Pref. Gifu Pref. consumes a large amount of cement to control land and water. Petroleum products are marketed well in Mie Pref. because a large quantity of naphtha is produced at group oil refineries in Yokkaichi.Areal difference between sales shares tends to be determined by the shares of the prefectures where the mills exist. Usually sales share extends remarkably in the prefecture where the mills exist and in adjoining prefectures.

Incidence of Gross Malformations and Vertebral Anomalies of Natural and Hatchery Plecoglossus altivelis

A total of 5,327 ayu were collected from the River of Yahagi, Aichi Pref., by cast net from April 1973 to November 1977 (Table 1). Numbers of young were collected from the Ibi River, Gifu Pref. (400), in May 1974, and the Nuchii River, Hokkaido (153), in July 1975 using the same gear. In May 1975, 335 young ayu were collected from Lake Biwa (Fig. 1). Juveniles were also obtained by artificial crossing of five pairs of adult fish from the Kiso River, Aichi Pref. The larvae were reared in a fishpond and fed zooplankton (Brachionus plicatilis) and artificial foods during culture. In this case, tem-

The Change of Agriculture in Mountain Villages around Industrialized Areas: A Case Study of Mikawa Mountainous Area (Aichi Pref.)

This article is an attempt to examine the change of agriculture and the trend of farmers in the Mikawa mountainous area (especially in Inabu cho and Toei cho) in the the period of higher economic growth after the Second World War. Mikawa mountainous area is in the northeastern part of Aichi pref. in Central Japan and extends near Toyota city where the automobile industry has rapidly grown in recent years (Fig. 1).In Japan, the demand of industrial labor has increased in the process of high economic growth since 1960. Many young laborers in rural areas have moved into metropolitan areas (especially Tokyo, Osaka, and Nagoya). As the result, many mountain villages, which are now out of the mainstream of traffic, have been seriously depopulated. But after about 1965, the industrialization began to spread in many mountain villages because of industries, moving from metropolitan areas to mountainous areas for cheap labor. Furthermore, even in mountain villages, the improvement of roads and the motorization made commuting possible between the villages and neighboring industrial cities. Consequently, mountain villages were newly organized. Therefore, the author tries to clarify the following point: 1) the structure and its change of the local labor market through the above industrialization; 2) the relation of such industrialization and the outflow of agricultural population; 3) the relation of such outflow and the change in agriculture; 4) the trend of farmers in the two settlements which the author chose.The following results were obtained:1) The structure of the local labor market in this area changed after about 1965. Many small industries like automobile parts, textiles and electronics have moved to this area for the aquiring of cheap labor (Table. 4) and in the western district of this area, many people began to commute automobile industry in Toyota city by microbus (Table. 3) Consequently the labor market of this area has divided into three classes. That is, (1) both the labor market in the neighboring city and “the first type” labor market, which pay the average wages in Aichi pref; (2) “the second type” labor market which employs cheap labor composed of female workers; (3) the labor market of daily employment which is composed of the building industry and the sawing industry (Fig. 4).2) Under such conditions, the outflow of agricultural population has increased (Table. 7). The author confirmed the fundamental tendency of “the outflow of agricultural population→the decline of agricultural production”. Though agricultural production (especially the production of rice, elephant feet and eggs) developed till about 1965, after which it began to decline. Many part-time farm-households which have remarkably increased, continue subsistence agriculture (monoculture of rice production). On the other hand, the production of broiler, tea and flowers shows a tendency to increasing development, but these products are produced by only a few upper class farmers.3) Observing the trend of farmers in the unit of the settlement, in O settlement, Inabu cho, commuting farmers have continued or even expanded their farming, and in K settlement, Toei cho, in about one third of the total farm-households, the members are old people, and they are willing to continue the subsistence agriculture while their son works outside of this settlement (Table. 9). Recently, it is said that the depopulation of mountain villages has slowed, but such a phenomenon has a background that the old household has been increasing. So, we must consider that mountainous areas have new problems beyond the above depopulation.Mikawa mountainous area is strongly connected to the automobile industry which has shown signs of prosperity during the recent economic depression. In that sense, this area is an exception in comparison with many other mountainous areas.

Some Regional Aspects of Roofing Tile Manufacture and the Market Areas in Japan

In Japan, roofing tile was introduced from China at the end of the sixth century. But it was not until the nineteenth century that roofing tile was utilized by many people and mass production began.Today, roofing tile manufacturing workshops and plants can be found throughout the entire country except in Hokkaido and Aomori prefecture. The distribution of the production, however, is uneven: Aichi, Hyogo and Saitama prefectures account for more than 60% of the total production of the country (Tab. 2, Fig. 6).The purpose of this paper, then, is to examine the spatial distribution of agglomerated roofing tile producing centers and their market areas, and to try to point out factors contributing to the development of such centers. Results obtained may be summed up as follows:(a) The distribution of the market areas of the roofing tile industry in Japan is shown in Fig. 6. Four major and two minor market areas are found. Of course, it must be understood that besides these market areas, many local markets of lesser significance are widely distributed throughout the country.(b) Western-Mikawa (Aichi pref.) and Southern-Awaji (Hyogo pref.) have been examined in detail as representatives of roofing tile centers initially developed on the basis of the abundance of local raw material. The Aichi center has grown in response to the active demand in Edo (Tokyo) since the end of the eighteenth century, similarly the Awaji agglomeration based on the heavy demands from Osaka since the end of the nineteenth century. Of course, the availability of water transportation was also important for the development of these production centers.(c) Recently, however, the raw material, the clay, in the vicinity of these production centers has been depleted, and the raw material had to be brought in from fairly distant places. In an effort to counteract such a handicap, “rationalization” of the production and management-such as the improvement of the kiln-has been undertaken.(d) As a result of these endeavours, the production cost has been reduced, and the volume of production have rather increased. The products from those centers have not only been able to maintain their longstanding reputation but also expanded their shares in the market. Moreover, the development of transportation networks, especially the growing use of lorry lines, has helped increse these tendencies.

Study on the Deepseated Weathering of Granites

No suitable method has yet been found for the study on the texture, the structure and the mineral composition of the deep weathered granites, which has been called the Masa. In this paper, it is reported that the writer has made the systematic study of the disintegrated and the weathered granites. Its method is the analysis of the relationship between the distance from the fault and the diameter of the particles, and also the analysis of the cumulative curve for the size distribution, the apparent specific gravity, the seismic sounding, the electric prospecting, the relief quantity. The area reseached by the writer covered nearly over the whole area of Rokko mountains, Hyogo Pref., Dogo Dist., Ehime Pref., Yashima, Kagawa Pref., Sanage Dist., Aichi Pref. and the other regions.

Geomorphic History of the Nishi-Mikawa Plain Situated along the Lower Course of the Yahagi River, Aichi Pref. Japan

Rising from the southern part of the Kiso Mountains, Central Japan, the Yahagi River flows southwestward through the narrow valley in the granitic area of Mikawa Plateau, one of the famous elevated peneplains in Japan. In the lower course area, this river flows down along the western foot of Mikawa Plateau, developing the broad lowland which consists of younger Pliocene unconsolidated deposits called Yadagawa Formation. It enters into the Mikawa Bay opening the pacific Ocean. This lowland is named Nishi-Mikawa Plain. The authers surveyed this area in order to make clear the geomorphic history. The main results are as follows: 1) The Nishi-Mikawa Plain is divided into six landform surfaces. They are Fujioka(200-60m in altitude), Miyoshi (130-35), Koromo (130-20), Hekikai (80-5), Koshido (50-35) and the alluvial surfaces. 2) Fujioka Surface is considered to be a depositional surface of Yadagawa Formation, one of the most important Pliocene deposits in Japan. It has the character of lacustrine deposits. Morphologically, Fujioka Surface is classified into two groups. The one is the flat topped hills situated in the northern part, and the other is a low relief hillland in the southwestern part. It is presumed that such a difference is caused by the difference of the lithological composition of Yadagawa Formation. Namely, in the northern part where the gravels prevail, the original flat surface is preserved, while in the southwestern part consisting of sands and silts, the surface has a tendency to erode. 3) Miyoshi surfaceis a high flat topped terrace, and is presumed to be a depositional surface of Miyoshi Formation which was accumulated by the Yahagi River. 4) Koromo Surface is the depositional terrace of Koromo Formation which was transported by the Yahagi. River, too. The northern part of this surface is an elevated fan and the southern part is an elevated delta. 5) Hekikai Surface is also the depositional terrace of Hekikai Formation derived from the Yahagi River Although Hekikai Formation has characteristic features of the fan or flood plain deposits in the north, some features of delta and neritic sediments are seen in the south. 6) While above mentioned surfaces are broadly developed in this region, Koshido Surface is locally distributed only along the Yahagi River. This surface is concluded to be the river terrace. In the lower course area, this terrace surface is buried with the marine deposits of Alluvial age. 7) It is interpreted that Miyoshi, Koromo and Hekikai Surfaces were formed during the stage of successive high sea level of Pleistocene Period, and the altitude of the estimated ancient shore line is about 80m in Koromo Surface, and about 20m in Hekikai Surface. 8) On the contrary, Koshido Surface was formed in the last low sea level stage just before the Alluvial transgression.

A STUDY ON THE GROWTH AND REARING METHODS OF THE FRY OF BLACK PORGY, MYLIO MACROOEPHALUS (BASILEWSKY)

Hitherto, many attempts have been made to rear the larvae hatched from the pelagic eggs of various kinds of marine fishes. However, notwithstanding the efforts made by many biologists and fish-culturists, no satisfactory method to raise the fry and to maintain their survival at a high percentage has yet been achieved. The authors made three trials in the artificial fertilization of the black porgy, Mylio macrocephalus. These three trials were carried out at the Iride fish market, situated on the wes-tern coast of Hamana Bay, on the 30th of April, the 7th of May and the 23rd of May, 1959. Rearing experiments were carried out at the Ikawazu Fisheries Laboratory, Aichi Pref. to which the fertilized eggs were transported from there. The eggs hatched out in 40-50 hours and 60-70 hours at water temperatures of 19°C and 17°C respectively (Table 1). As food for the hatched out larvae, substantial amounts of several kinds of protozoa were previously cultured and given to them from a few days after hatching. It was observed that the fry, shortly before the yolk sac was entirely absorbed, namely at the age of two to three days after hatching, began to feed on fine Dino-flagellata, Oxyrrhis sp. (10-30μ×8-15μ). Subsequently, at fry measurements of 3-3.5mm. in total length, a species of Spirotricha, Stylonchia sp. (50-100μ×30-40μ) were largely fed on by the fry. Later, as the fry grew, they were observed to take in various living food organisms of gradually larger size in direct relation to their growth. For instance, in our experiments it was observed that the fry took the nauplius of copepoda or barnacle at 4-4.5mm. in total length, ie. 9-12 days after hatching; the nauplius of brine shrimp at about 5mm. in total length, ie. 15 days after hatching; young mysid shrimp at about 7mm. in total length, ie. 3-4 weeks after hatching and finally the fry was able to feed on chopped fish when they measured about 15mm. in total length, ie. 6-7 weeks after hatching (vide Fig. 2). As to the number of fry that survived, we obtained 638 young porgies (13% to the number of the hatched larvae) after 52 days in the first round of rearing, 614 fry (17.5%) after 45 days in the second trial and 102 fry after 60 days in the last trial. In each trial to raise the larvae, a considerablly high mortality occurred at the age of 6-8 days after hatching. It is observed that these days are the period when the fry change their diet from protozoa to larger food organisms. Further study is necessary so as to make it possible to improve the survival rate of the fry especially during this critical period when the fry changes its diet from protozoa to larger living organisms. Once this critical period was crossed it was observed that the fry grew rapidly, reaching about 4.5mm. after two weeks, 10.1mm. after a month and 32.0mm. (1.03gm. in body weight) at the age of two months (Fig. 3).

Observations on the Ancient Horses of Japan

I tried to classify the ancient horses of Japan by comparing the limb bones of the ancient horses with those of the existing native horses such as the Kiso horse, the Misaki horse, the Hokkaido horse, the Tokara pony, the Korean pony, the Mongolian horse, etc.1. The ancient horses of Japan can be classed according to their size, as Small and Medium sized. The horses of Izumi (Jomon Period, Kagoshima Prefecture), Tayui (First phalanx, Yayoi Period, Nagasaki Pref.), Urigo (Yayoi Period, Alchl Pref.), Hirade (Haji Period, Nagano Pref.), Yoyatna (Jomon Period, China Pref.) and Nogami (Jomon Period, Tochigi Pref.) belong to the Small category, and those of Atsuta (Yayoi Period, Aichi Pref.), Hirai (Jomon Period, Aichi Pref.), Kamoi (Yayoi Period, Kanagawa Pref.) and Tabata (Yayoi Period, Tokyo Metropolis) to the Medium sized category. The horses of Karakami and Haranotsuji (Yayoi Period, Iki Island in the Tsu Strait between Japan and Korea, Nagasaki Pref .) are intermediate between the Small and the Medium sized categolies. The horses of Mirinri (Korean stone age) are similarly Medium sized.2. The native horses of Japan can be classed according to their size as belonging to the Island type (Tokara pony) or the Inland type (Kiso, Misaki and Hokkaido horses). The height at withers of the former is about 114.5cm and that of the latter is 132cm or thereabouts. The ancient horses of Japan that belong to the Small sized category are nearly all of the same size as the Tokara pony which is of the Island type, and their size is nearly the same as that of the Korean pony and the horses of the southeastern region of Asia (Miyako pony, Hainan Island pony and Szechwan pony). Those that are of Medium size are nearly all the same in size with the native horses of Inland type and Mongloian horse in a narrow sense.3. The Small sized horses such as the Tokara pony, which were called three feets horses or Kakaba (so small as able to ride under the flowering trees ), were kept in Korea and in south-west China on the Continent (Yunnan, Kwangsi and Hainan) from the 2nd century B. C. to the 10th century A. D. But, in the southern part of Indo-China and Indonesia, there is no reference concerning the existence of horses in ancient Chinese literature.4. In the stone age of Japan, the remains of horses are very rare in comparison with those of the wild boar or deer. There is no evidence that the bones were broken or crushed for food, and judging from the condition of the teeth, they seem to have reached a very old age. I believe therefore, that the horses represented by these remains which were found in the shellmounds were well cared for by the people of the stone age.

愛知縣沿岸の年平均潮位の変化

The anther studied the changes in the heights of yearly mean sea levels at the mareograph stations situated in Aichi Prefecture and at the mouth of Kisogawa River. It is suggested from the results of the present study that the land in Aichi Pref. sank gradually from 1931 to 1938, then it rose since 1938, and the upward movement continued till it begins to sink again in 1944. The local irregularities in rising or sinking of the land in the region under consideration are not remarkable but for the land of Kii Peninsula where the general mode of deformation was of different type.

Natural Gas in the Western Region of Nagoya City

Chemical characters of the quaternary natural gas and underground water are shown on the following tables and figures.On account of the invasion of the underground water current into the natural gas deposits caused by ordinary wells for agricultural water supply, there is no payable gas field in the downstream districts of the River Kiso and Ibi.But the writer thinks it is quite neccessary to survey the midstream district of these rivers (Amagun, Nakashima-gun, Haneshima-gun, Aichi Pref: Yasuhachi-gun, Yoro-gun, Umitsu-gun, Gifu Pref: Kuwana-gun, Mie Pref.) where the gas quality is better and the present wells are few.
