The problem of heat balance is one of the most importan factors in applied climatology especially associated with the water balance. Japan is an extremely rainy country and suffers more frequently from flood damage than from drought. So water is generally excessive excepting in. limited seasons and areas in which the deficit of summer heat often causes crop damage especially to rice in extensive areas in the northern half of Japan. For this reason, the author has studied the radiation problem mainly from the geo-graphical and climatological points of view. In this paper, he deals with the geographical distribution of horizontal solar intensity in Japan and explains the Bai-u or Plum Rain from the heat balance standpoint.
The main items are as follows:
1. Observational materials with the table of monthly normals for horizontal solar intensity including sky radiation.
2. The annual march and the geographical distribution of solar intensity.
3. The transmission of solar intentity in Japan expressed by a newly devised index.
4. The influence of Bai-u or Plum Rain, on the temperature march in the summer season as explained by heat balance.
In this paper, detailed description is difficult because of many limitations.
The full paper in English will be completed in the near future after further study.

There are broad Diluvial uplands on both sides of the lower course of the River Kuji, to the south of Abukuma plateau. Basing on the field observations and the analysis of terrace deposits, the author classified the uplands into three terraces, and explained the processes of their formation. The main subjects discussed in this paper are summerized as follows:
1. The Diluvial uplands are classified into three terraces with altitudes of 80-110m (Upper), 50m (Middle) and 20-30m (Lower). Among them the Middle is the most extensively distributed in this area, and continues to the terraces situated along the upper course of the River Kuji (fig. 1).
2. Three terraces are similarly composed of sand and gravel beds lying unconformably on Tertiary system and are covered by aeorian volcanic ash which contains a pumice band 10-20cm thick. Upper terraces are correlated with so-called Tame terraces. the Middle with Musashino, and the Lower with the Intermediate terrace between Musashino and Post-Loam terraces in the southern part of Kanto district.
3. The author investigated the thickness of gravel beds in the Middle and Lower terraces, and made the machanical and lithological analysis of gravels, from which she inferred the environment of deposition and the process of terrace formation (figs. 1, 3, 4 and tab. 1). The major part of the Middle terrace is an elevated coastal plain consisting of littoral deposits. The former shoreline has been elevated some 50 meters, which is determind by the presence of exotic gravels in the eastern part of the terrace. The deposits of the Middle terrace may be correlated with the upper part of Narita formation deposited in the Palaeo-Tokyo Bay in late Pleistocene. The area studied had occupied the northern limit of the bay. The Lower terrace is of fluviatile origin formed by the extended courses of the Rivers Kuji. Sato and Naka.

Bis heute ist der Wortsinn des Berges “Fuzi”, Fudschi-jama auf Deutsch, von vielen Gelehrten erklirt worden durch ein Aino Wort “Huchi” (=die Grossmutter, die Göttin des Feuers). Aber Dr. K. Kindaiti bewies, dass die Auslegung ein Missverständnis war. Doch es gibt hieriiber noch keinen treffenden Aufschluss in der N issenschaftlichen Welt.
Hierauf land der: Verfasser überzeugende Beweise, dass das Wort “Fuzi”, ein altes echt japanisehes Wort ist, das die Schönheit der langen Abdachung des Berges bedeutet.
(1) Auf Japanischen Inseln gibt es den Dialekt “Fuzi” welehes die lange Abdachung des Berges bedeutet. Auch der Regenbogen und die Glyzinie, die sehön in der Luft hängen, werden noch jetzt im Dialekt als “Fuzi” bezeichhnet.
(2) Die vielen Ortsnamen “-fuzi”, deren Ursprünge die wie obenstehende Bogengestalten sind, verbreiten sick auf den Japanischen Inseln. (Siehe Abb. I).
(3) Der Verbreitungstypus der Ortsnamen von “fuzi” hat eine Struktur der konzentrischen Kreise, deren Zentrum sick in Yamato befindet. Es g_??_bt keine Beziehung zwischen dem Gebiete der, Verbreitung und Hokkaido als Heimat der Aino.
Der Verfasser ermittelte auch, dass die Ortsnamen “-fuzi” nicht so alt sind, wie bis heute von vielen Gelebrten angenommen wilyde; nämlich die Namen der Berge “-fuzi” kamen in der Zeit vom 3. _??_7. Jahrhundert vor, und die der vielen Siedlungen “-fuzi” (Siehe Abb. 1) im 9. J. H..
Die Verbreitung des Namens “Fuzi-san” (-san=-yama=Gebirge) mit dem Namen “Asalma- yama” (“Asama” stammt von “Azama” =Name des Seevolkes in alter Zeit) entsprechen der Entw icklungsregion der Berg-religion von “Fuzi-sengen” (“-sengen” ist die Japanische Farallele des chineschischen Zeichens “Asama”). Der Zasanlmenhang zwischen dem beiden Verbreitungen von Berg und Religion bedeutet, dass diese Bergreligion sich im Gesichtsfeld von “Fuzi-san” entwickelt hat. Das Gesichtsfeld von “Fuzi-san” ist ebenso ausdehnbar, wie die Kreisflache mit dem Halbmesser von 223 KM. (Siehe Abb. 3).
Auch die Name “Fuzimi” (Von aus kann man den “Fuzi-san” sehen) verbreiten sich in diesem Kreise (Siehe Abb. 4).

Abb. 2: Verbreitung der Namen “Azumi”, “Azuma” and “Asama”. Diese N amen sind für Berge and Siedlungen. “Azwni” ist der älteste. “Azuma” and “Asama” folgen nach “Azumi. Diese stammers von Seevolksnamen.
Abb. 3: “Fuzi” and “Asama” -Bergnamen Zeichen des Hiihnerauges ist “Fuzi-san”. Kleine Kreise sind Namen des Berges “Fuzi”, schwarze Punkte sind Namen des Berges “Asalma-yama”.
Abb. 4: Verbreitung des Namens “Fuzimi” “Fuzimi”. bedeutet, dass von -aus man den “Fuzi-san” sehen kann.

The results of my investigation on the centers of population, for the period of 1920 to 1954, of each prefecture in Kyushu and of Kyushu as a whole, are shown in List 1, Diagram 1 and 2. The shift of the centers of population can be classified into the following four types.
The first type is seen in a prefecture which has in some part of it a rapidly developing industrial district. The center of population in such a prefecture had had a tendency to move to the industrial district before the war, but began to move in the opposite direAion in the period of post-war, confusion, and then since about 1947, it has shown again the same tendency as in the pre-war days. Miyazaki, Fukuoka, and Kyushu as a whole are the examples of this type.
The second type is seen in prefectures having several attracting centres, whose interrelatoin make the shift of population center exceedingly complicated. Kumamnoto and -Nagasaki are the examples of this type.
The third type is seen in those prefectures where the capital cities and the centers of population are virtually the same so that the shift of center has been very slight indeed. Examples are to be found in Oita, Saga, and Kagoshima exclusive of Amami-Oshim a.
The fourth and the last type is that of a prefecture in which, with a remarkable decrease of population in a certain district, the center of population moves in the opposite direction in almost a straight line. Kagoshima prefecture, inclusive of Amami-Oshima whose Poulation is rapidly decreasing, is a good example of this type.
