Part I Developments in Land, Infrastructure, Transport and Tourism Administration that Underpin Japan’s Economic Growth ~ Strategic infrastructure management that brings about productivity revolution ~ Section 1 Japanese Economy and Its Surrounding Conditions I Relationships between Japanese Economy and Land, Chapter 1 Chapter 1 Infrastructure, Transport and Tourism Administration Relationships between Japanese Economy and Land, Infrastructure, Transport and Tourism Administration and Tourism Transport Relationships between Japanese Economy and Land, Infrastructure, Chapter 1, Relationships between Japanese Economy and Land, Infrastructure, Transport and Tourism Administration, on the assumption of discussions described in chapter 2 and following sections, looks at the significance of the effects infrastructure development has on economic growth with awareness of severe circumstances surrounding the Japanese economy from the perspective of history and statistical data. Section 1, Japanese Economy and Its Surrounding Conditions, provides an overview of an increasingly declining population, especially that of a productive-age population, to become a super aging society with an estimated aging rate of close to 40% in 2050, and a severe fiscal position due to rapidly growing, long-term outstanding debts and other circumstances. Section 2, Economic Trends and Infrastructure Development, looks at how infrastructure has supported peoples’ lives and the economy of the time by exploring economic growth and the history of infrastructure development (Edo period and post-war economic growth period). In international comparisons of the level of public investment, we describe the need to consider Japan’s poor land and severe natural environment, provide an overview of the stock effect of the infrastructure, and examine its impact on the infrastructure, productivity, and economic growth. Section 1 Japanese Economy and Its Surrounding Conditions 1 Japan’s Population Conditions and Future Estimates (1) Changes in population and productive-age population Because of the progression of declining birthrate and aging population, the total population of Japan is falling after peaking in 2008, with the productive-age population also decreasing after the peak in 1995. The preliminary figure from the National Census in 2015 showed that the total population of Japan declined for the first time since the quinquennial Census, falling to 127,110,000. According to the projection of the National Institute of Population and Social Security Research (median projection for birth/death), the total population is projected to decline to 116,620,000 in 2030 and 86,740,000 in 2060 (down 32.3% when compared to 2010), with the productive-age population projected to decline to 67,730,000 in 2030 and 44,180,000 in 2060 (down 45.9% when compared to 2010) (Figure 1-1-1). 2 WHITE PAPER ON LAND, INFRASTRUCTURE, TRANSPORT AND TOURISM IN JAPAN 2016 Section 1 Japanese Economy and Its Surrounding Conditions Figure 1-1-1 Changes in Population Structure in Japan (1,000 people) (%) I 140,000 80 Estimates Chapter 1 70 120,000 60 100,000 Relationships between Japanese Economy and Land, Infrastructure, Transport and Tourism Administration and Tourism Transport Relationships between Japanese Economy and Land, Infrastructure, 50 80,000 40 60,000 30 40,000 20 20,000 10 0 0 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 2040 2045 2050 2055 2060 (year) Aged 0–14 Aged 15–64 Aged 65 and over Ratio of young Aging rate (right axis) Ratio of productive-age population (right axis) population (right axis) Source) “National Census” and “Population Estimates” by the Ministry of Internal Affairs and Communications for dates up to 2010, “Population Estimates” by the MIC for 2015 data (as of October 1, 2015); estimates are calculated by the MLIT from the median estimates of “Japan’s future population estimates” (estimates from January 2012) by IPSS.

Also, projected changes in population by smaller municipality units show that the smaller the size of municipality is, the higher the rate of population decline will be; municipalities with populations less than 10,000 are projected to see their population decrease by about half during the period from 2010 to 2050. Population increases are projected only in limited regions including the Tokyo and Nagoya areas, and depopulation is expected to become more severe across Japan.
