  • Recent Trends in Rural to Urban Migration in Japan: the Problem of Depopulation
    Recent Trends in Rural to Urban Migration in Japan: the problem of Depopulation 著者 KAKIUCHI George, H., HASEGAWA Masami 雑誌名 The science reports of the Tohoku University. 7th series, Geography 巻 29 号 1 ページ 47-61 発行年 1979-06 URL http://hdl.handle.net/10097/45077 Recent Trends in Rural to Urban Migration in Japan : the Problem of Depopulation George H. KAKIUGHP and Masami HASEGAWA** Introduction The large-scale out-migration of Japan's rural population into the cities became very noticeable during and after the latter half of the 1950's, causing some serious social and economic problems. Most of those leaving the rural areas have gone to the larger cities of the Pacific Coast Manufacturing Belt, stretching narrowly for some 600 miles along the coast from the Kanto plain through the Inland Sea to northern Kyushu (Map 1). In fact, in 1968, almost half of the migrants went to the two metropolitan areas centering on Tokyo and Osaka.') The population concentration has been such that the Pacific Coast Manufacturing Belt , with only 22.9% of the total land area of Japan, accounted for 55.8% of the total population and 71.0% of the manufacturing by value in 1975.2) Once the migrants have left their rural villages, very few return. This has created severe problems associated with overcrowding within the highly industrialized and urbanized Belt , while in many of the outlying rural areas critical problems related to underpopulation have arisen. The out-migration of labor and population from the villages is undoubtedly strongly influenced by the large

Main flows, excluding early 1940s. were from rural areas to urban areas (major municipalities zones). From the begining the dominant cities of population concentration were Tokyo and Osaka. This tendency continued till the end of 1950s. There was a shift in migration patterns in 1960s, characterized by: a) increase in migration rates from 3 major cities zones (Tokyo. Osaka. Nagoya) to non urban zones b) inter big cities areas migration numbers grew. c) inter-prefectural migration flows grew. In mid 1970s internal migration reached balance, in particular this among big cities zones and non-urban zones. Furthermore, in the begining of 1980s the increase in big cities zones influxes was recorded again (Kurota. 1976: 61-63). In 2005 almost 50% of Japanese population resided in 3 major cities zones while other regions accounted for 49.8% of total polulation. According to the National Institute of Population and Social Security Research. by.2035 year 3 big municipalities areas would occupy 53.2% of total population and their working age population will account for 54.7% of total population1 J http://www.ipss.go.jp/syoushika/rohkei/suikei07/suikei.html Access: 28.04.2011.

All rights reserved Migration in East Asia: Japan in Comparative Focus David W. Haines George Mason University Makito Minami National Museum of Ethnology Shinji Yamashita University of Tokyo This special two-day conference on migration, held May 31–June 1, 2007, at Japan’s National Museum of Ethnology (Minpaku) in Osaka, was one of the first and most comprehensive meetings of scholars on the full dimensions and implications of migration both to and from Japan. It was also a valuable opportunity to reconsider international migration from an East Asian vantage point – and especially convenient for non-Japanese since the papers were written in English.1 MIGRANTS IN JAPAN Japan is now very much a country of migration, with sizeable numbers of people moving both outward and inward across its borders. The number of foreigners residing in Japan exceeds two million and includes a very wide range in type of migration (labor, refuge, education, marriage) and country of origin. Conference papers provided especially detailed discussion of six groups: Koreans, including the quite distinctive experience of Jeju Islanders and ethnic Koreans from China; “oldcomer” and “newcomer” Chinese; Brazilians, with attention to their experience in Japan and the effects on sending communities in Brazil; Filipinos, ranging from early, widely respected boxers and musicians to more recent, generally disesteemed entertainers and healthcare workers; Vietnamese, who now include early official refugees and more recent students, workers, and international spouses; and Nepalis, including their complex migration routes throughout East Asia.

ABSTRACT: This paper examines the economic segmentation model in explaining 1985-86 Japanese interregional migration. The· analysis takes advantage of statistical graphic techniques to illustrate the following substantive issues of interregional migration: (1) to examine whether economic segmentation significantly influences Japanese regional migration and (2) to explain socioeconomic characteristics of prefectures for both in- and out-migration. Analytic techniques include a latent structural equation (LISREL) methodology and statistical residual mapping. The residual dispersion patterns, for instance, suggest the extent to which socioeconomic and geopolitical variables explain migration differences by showing unique ·..:. clusters of unexplained residuals. The analysis further points out that extraneous factors such as high residential land values, significant commuting populations, and regional-specific cultures and traditions need to be incorporated in the economic segmentation model in order to assess the extent of the model's reliability in explaining the pattern of interprefectural migration. This paper examines two theories of migration is held to be an important way regional migration patterns in Japan: ( 1) by which workers respond to changing the economic opportunity thesis and (2) economic opportunities and thereby re­ the economic segmentation-model.

  • Japan, 1944-47 Keywords: Migration; War; Demographic Change
    The Geography of Wartime Demographic Change: Japan, 1944-47 Keywords: Migration; war; demographic change; Japan; census; World War II Abstract This study examines the geography of demographic change in Japan at the end of World War II (1944-47) in relation to its preceding population growth trajectory. The trajectory is estimated using Japanese Census data at the prefecture level between 1920 and 1940, and subsequent annual population counts for 1944, 1945, 1946, and 1947 are compared to this trajectory to characterize and understand the impact of the War. The findings illustrate and highlight the highly unusual geographic and temporal patterns of population change at the close of the War. Key findings include a systematic characterization of prefectures according to their experience over the four years in four groups, the two largest cities, other urban prefectures, a ring of rural prefectures surrounding these urban prefectures, and peripheral rural prefectures. Similarly, each of the four years is characterized based on the unique pattern of population change specific to that year. In keeping with broad pre-War patterns, 1944 reveals a slight loss of population in rural areas and a slight gain in urban areas. 1945 is dominated by urban-to-rural migration as urban dwellers fled the cities to take refuge in rural areas from the Allied strategic bombing campaign. 1946 shows a partial reversal of the trend seen in 1945. The highlight of 1947 is the repatriation of large numbers of Japanese citizens from the territories lost by Japan in the aftermath of the War. Keywords: Migration; war; demographic change; Japan; census; World War II Introduction In terms of loss of life, World War II was “history’s deadliest quarrel” (Clodfelter, 2008, p.581).

  • What Factors Have Caused Japanese Prefectures to Attract a Larger Population Influx?
    What factors have caused Japanese prefectures to attract a larger population influx? Keisuke Kokubun1 1 Economic Research Institute, Japan Society for the Promotion of Machine Industry Abstract Regional promotion and centralized correction in Tokyo have long been the goals of the Government of Japan. Furthermore, in the wake of the recent new coronavirus (COVID-19) epidemic, the momentum for rural migration is increasing, to prevent the risk of infection with the help of penetration of remote work. However, there is not enough debate about what kind of land will attract the population. Therefore, in this paper, we will consider this problem by performing correlation analysis and multiple regression analysis with the inflow rate and the excess inflow rate of the population as the dependent variables, using recent government statistics for each prefecture. As a result of the analysis, in addition to economic factor variables, variables of climatic, amenity, and human factors correlated with the inflow rate, and it was shown that the model has the greatest explanatory power when multiple factors were used in addition to specific factors. Therefore, local prefectures are required to take regional promotion measures focusing on not only economic factors but also multifaceted factors to attract the outside population. Keywords: population inflow rate; excess inflow rate; Covid-19; economic factors; hierarchical regression analysis; climatic factors, amenity factors, human factors; prefectures; Japan Introduction Japan has a heavily concentrated population in Tokyo, the capital of Japan, and its problems have been discussed concerning efficiency, urban traffic congestion, housing shortages, environmental pollution, disaster risk, and rural depopulation (Hirata, 2019; Porter, 1990).

  • A Review of Recent Population Changes in Japan*
    Hitotsubashi Journal of Social Studies 19 (1987) 1 5-30. C The Hitotsubashi Academy A REVIEW OF RECENT POPULATION CHANGES IN JAPAN* MASATOSHI YORIMITSU I Introduction It is frequently pointed out that Japanese society is now facing a major turning point in terms of the economy and people's lifestyle that characterized the postwar Japanese social structure (Economic Planning Agency, 1983, pp. 4-9). First, basic economic conditions have been transformed from 'high' economic growth to 'low' and 'stabilized' growth. This change can be attributed to many factors, including the oil shocks, which directly hit Japan during the period of highpaced economic growth. At the same time, many industries that accounted for the post-war economic growth have reached a 'matured' stage and have lost their power to drive the Japanese economy. The industrial structure has shifted from the heavy and chemical industries to the knowledge- intensive and service-oriented industries (Economic Planning Agency, 1982, pp. 96-99). Second, the Japanese popL]lation is expected to have one of the world's most aged structure (Management and Coordination Agency, 1984). Birth rates have declined since the sharp drop following the baby boom of 1945-1950, and Japanese population growth will continue to slow down in the coming years. This aging of society effects on the economy in two ways; the shrinkage in labor supply of young adults who are thought to be most adaptable to technical changes will continue, and the vast accumulation of aged population addresses a serious problem of how to guarantee employment and support for them (Popu- lation Problem Council, 1984).

This vision of diverse Japan will be extended by developing new ways of accommodation for the contemporary immigrants, especially increas- ing wave of international students and refugees. In fact, this process had been strongly pushed by the government since 2014, through policy changes within Japan Revitalization Project (JRP). This paper will discuss and analyses current effects of those migration policies focusing on international students, migrants and refugees. The strategy made by the Japanese authorities is giving major ad- vantages to “newcomers” wanting to work or study. However, at the same time, people seeking refuge within borders of Japan still are facing many obstacles due to bureaucracy barriers. Keywords: Japan, Students, Immigration, Policy * Ph.D. Candiate.

This thesis examines Oonan Town in Shimane Prefecture as a case study, as it is a rural town that has been successful in getting in-migrants back into the community. Through oral, biographical interviews, participants reported factors that played a significant role in the migration decision-making process. Data show that in- migrants in Oonan Town were largely affected by four factors, which are 1) family ties, 2) life course events, 3) lifestyle preferences, and 4) financial factors.
