Throughout the Common Era, Japan's population saw relatively steady growth between each century. Failed invasions and distance from Asia's mainland meant that Japan was unaffected by many pandemics, primarily bubonic plague, therefore its development was not drastically impeded in the same way as areas such as China or Europe. Additionally, religious practices meant that hygiene was prioritized much more in Japan than in other regions, and dietary customs saw lower rates of meat consumption and regular boiling of water in meals or tea; both of these factors contributed to lower rates of infection for many parasitic or water-borne diseases. Fewer international conflicts and domestic stability also saw lower mortality in this regard, and Japan was an considered an outlier by Asian standards, as some shifting trends associated with the demographic transition (such as lower child mortality and fertility) began taking place in the 17th century; much earlier time than anywhere else in the world. Yet the most significant changes came in the 20th century, as Japan's advanced healthcare and sanitation systems saw drastic reductions in mortality. Challenges Japan's isolation meant that, when pandemics did arrive, the population had less protection and viruses could have higher mortality rates; smallpox has been cited as the deadliest of these pandemics, although increased international contact in the late 19th century brought new viruses, and population growth slowed. Earlier isolation also meant that crop failure or food shortages could leave large sections of the population vulnerable, and, as mentioned, the Japanese diet contained relatively little meat, therefore there was a higher reliance on crops and vegetables. It is believed that the shortage of arable land and the acidity of the soil due to volcanic activity meant that agriculture was more challenging in Japan than on the Asian mainland. For most of history, paddy fields were the most efficient source of food production in Japan, but the challenging nature of this form of agriculture and changes in employment trends gradually led to an increased reliance in imported crops. Post-Sakoku Japan Distance from the Asian mainland was not the only reason for Japan's isolation; from 1603 to 1853, under the Tokugawa shogunate, international trade was restricted, migration abroad was forbidden, and most foreign interaction was centered around Nagasaki. American neo-imperialism then forced Japan to open trade with the west, and Japan became an imperial power by the early-1900s. Japanese expansion began with a series of military victories against China and Russia at the turn of the century, and the annexation of Taiwan, Korea, and Manchuria by the 1930s, before things escalated further during its invasion of China and the Second World War. Despite its involvement in so many wars, the majority of conflicts involving Japan were overseas, therefore civilian casualties were much lower than those suffered by other Asian countries during this time. After Japan's defeat in 1945, its imperial ambitions were abandoned, it developed strong economic ties with the West, and had the fastest economic growth of any industrial country in the post-WWII period. Today, Japan is one of the most demographically advanced countries in the world, with the highest life expectancy in most years. However, its population has been in a steady decline for over a decade, and low fertility and an over-aged society are considered some of the biggest challenges to Japanese society today.

Historical chart and dataset showing Japan population growth rate by year from 1961 to 2023.

In 2023, the total population in Japan slightly decreased to just below 125 million people compared to the previous year, with the female population reaching around 63.9 million, as compared to 60.5 million men. The oldest population in the world  Japanese society is facing severe demographic problems such as decreasing birthrates, remaining under one million births annually recently, and a thereby aging population. The country’s average age lies at around 48 years, making its population the oldest in the world. Elderly people aged 65 years and older accounted for about 29 percent of the population in 2023. According to a forecast, the age group 65 years and older would make up approximately 39 percent of the Japanese population by 2070. Challenges with the demographic shift The rapid aging of the society poses significant economic and sociopolitical challenges to the country, as the workforce will continue to shrink while increasingly more elderly will receive long-term support. Currently, close to seven million Japanese require long-term care, leading to national benefit expenses of over 14 trillion yen annually, including in-home and community-based services.

Graph and download economic data for Population, Total for Japan (POPTOTJPA647NWDB) from 1960 to 2024 about Japan and population.

In 1800, the population of Japan was just over 30 million, a figure which would grow by just two million in the first half of the 19th century. However, with the fall of the Tokugawa shogunate and the restoration of the emperor in the Meiji Restoration of 1868, Japan would begin transforming from an isolated feudal island, to a modernized empire built on Western models. The Meiji period would see a rapid rise in the population of Japan, as industrialization and advancements in healthcare lead to a significant reduction in child mortality rates, while the creation overseas colonies would lead to a strong economic boom. However, this growth would slow beginning in 1937, as Japan entered a prolonged war with the Republic of China, which later grew into a major theater of the Second World War. The war was eventually brought to Japan's home front, with the escalation of Allied air raids on Japanese urban centers from 1944 onwards (Tokyo was the most-bombed city of the Second World War). By the war's end in 1945 and the subsequent occupation of the island by the Allied military, Japan had suffered over two and a half million military fatalities, and over one million civilian deaths.

The population figures of Japan were quick to recover, as the post-war “economic miracle” would see an unprecedented expansion of the Japanese economy, and would lead to the country becoming one of the first fully industrialized nations in East Asia. As living standards rose, the population of Japan would increase from 77 million in 1945, to over 127 million by the end of the century. However, growth would begin to slow in the late 1980s, as birth rates and migration rates fell, and Japan eventually grew to have one of the oldest populations in the world. The population would peak in 2008 at just over 128 million, but has consistently fallen each year since then, as the fertility rate of the country remains below replacement level (despite government initiatives to counter this) and the country's immigrant population remains relatively stable. The population of Japan is expected to continue its decline in the coming years, and in 2020, it is estimated that approximately 126 million people inhabit the island country.

Japan is one of the highly urbanized and severely aging society. In an aging society, chronic disease and disability are prevalent, and the population is sensitive to environmental issues and climate change. To detect the impacts of population changes, formulate the population and public health policies, and assist environmental applications, the high-resolution and accurate gridded population dataset is strongly desired. To provide basic data for these studies, we create an open access annual dataset containing the total, male, and female population counts in each grid at a 500-m resolution from 2001 to 2020. The yearly population dataset is based on the 4th-level mesh data from the Statistics Bureau of Japan to make it easy to use. The dataset is provided here alongside the descriptions of the data and methods used in the fitting, cross-validation, and prediction processes.

The total population data are stored in 20 attributes, named the “X0000” style. The “0000” of “X0000” represents the four-digit year. For example, the attribute “X2001” reports the total 2001 population in the mesh. The dataset also preserves the direct output from the random forest and the logarithms of the total population. The attributes of the logarithms of the total population in each year are named in “X0000_log” style. The “0000” of “X0000_log” also stands for the four-digit year. The attributes of the female population, the logarithm of the female population, the male population, and the logarithm of the male population are written as “X0000_fema”, “X0000_fe_l”, “X0000_male”, and “X0000_ma_l”, respectively.

The accuracy of the models constructed to predict the total, male, and female populations are 92.09%, 91.92%, and 92.16%, respectively.

With approximately ** million inhabitants, Tokyo Prefecture was the largest prefecture based on population size in Japan as of 2023. The smallest prefecture in this regard was Tottori Prefecture, which in the same year counted about ******* residents. Rural depopulation Like many industrial economies, Japan is facing the problem of depopulating rural areas. While the birth rate continues to decline, many young people decide to migrate from small towns and villages to large cities like Tokyo or Osaka for higher education and employment. The population of Tokyo Prefecture has shown substantial growth over the past decades and consists largely of working age citizens. Smaller communities are trying to counteract the depopulation process with initiatives meant to invite younger workers and tourists back. Migration to Japan Japan is often described as a very homogenous society, with a low share of foreign residents. Despite the declining birthrate and many businesses experiencing a labor shortage, companies have been hesitant to employ foreign workers, in part due to the strict immigration laws. The Japanese Government has tried to ease immigration restrictions and encourage foreigners to work in Japan. The largest share of foreign workers in Japan, however, is residing in the county with a permanent residence or as the family member of a Japanese national.

Over the last decade, Japan’s population has aged more and more, to the point where more than a quarter of Japanese were 65 years and older in 2022. Population growth has stopped and even reversed, since it’s been in the red for several years now.

It’s getting old

With almost 30 percent of its population being elderly inhabitants, Japan is considered the “oldest” country in the world today. Japan boasts a high life expectancy, in fact, the Japanese tend to live longer than the average human worldwide. The increase of the aging population is accompanied by a decrease of the total population caused by a sinking birth rate. Japan’s fertility rate has been below the replacement rate for many decades now, mostly due to economic uncertainty and thus a decreasing number of marriages.

Are the Japanese invincible?

There is no real mystery surrounding the ripe old age of so many Japanese. Their high average age is very likely due to high healthcare standards, nutrition, and an overall high standard of living – all of which could be adopted by other industrial nations as well. But with high age comes less capacity, and Japan’s future enemy might not be an early death, but rather a struggling social network.

According to a survey conducted in November 2023, most women in Japan were within the normal range of the body mass index (BMI). Around 69.7 percent of female respondents in the age group 30 to 39 years were of normal weight in terms of BMI, while about 12.4 percent were overweight. Weights control in Japan The majority of deaths in recent Japanese society are caused by lifestyle diseases. In order to reduce the number of deaths from lifestyle diseases, the Japanese government implemented a new annual metabolic syndrome examination in 2008 for citizens aged over 40 years old. People who are classified as having metabolic syndrome or pre-metabolic syndrome at the examination receive advice and support from a nutritionist to improve their diet and lifestyle habits. The government also introduced a new license Tokuho in 1991 for food and beverages that contain ingredients that can have a positive influence on the physiological function. Major companies in Japan currently produce a lot of food and drink products that can meet the requirement of the license. Despite those measures, the share of people in Japan that are classified as overweight has not fluctuated much in recent years. As of 2019, close to 32 percent of Japanese men were classified as obese. Underweight among young women In contrast to the people categorized as overweight, young female Japanese are facing an underweight problem. According to the survey, approximately 24 percent of women in their twenties and 18.3 percent of girls below 20 years old were reported as being underweight. The Japanese health ministry pointed out that the dissemination of beauty standards in society and media, alongside the flooded information about diet methods, are facilitating young Japanese women’s desire to be “thin.” To reduce the risk of health disorders, such as amenorrhea and osteoporosis among women, the government has set the goal of less than 15 percent of the female population under 30 years old to be underweight by 2032.

Longitudinal data set of a nationally representative sample of the population aged 65 and over in Japan, comparable to that collected in the US and other countries. The first two waves of data are now available to the international research community. The sample is refreshed with younger members at each wave so it remains representative of the population at each wave. The study was designed primarily to investigate health status of the Japanese elderly and changes in health status over time. An additional aim is to investigate the impact of long-term care insurance system on the use of services by the Japanese elderly and to investigate the relationship between co-residence and the use of long term care. While the focus of the survey is health and health service utilization, other topics relevant to the aging experience are included such as intergenerational exchange, living arrangements, caregiving, and labor force participation. The initial questionnaire was designed to be comparable to the (US) Longitudinal Study of Aging II (LSOAII), and to the Asset and Health Dynamics Among the Oldest Old (AHEAD, a pre-1924 birth cohort) sample of the Health and Retirement Study (HRS), which has now been merged with the HRS. The sample was selected using a multistage stratified sampling method to generate 340 primary sampling units (PSUs). The sample of individuals was selected for the most part by using the National Residents Registry System, considered to be universal and accurate because it is a legal requirement to report any move to local authorities within two weeks. From each of the 340 PSUs, 6-11 persons aged 65-74 were selected and 8-12 persons aged 75+ were sampled. The population 75+ was oversampled by a factor of 2. Weights have been developed for respondents to the first wave of the survey to reflect sampling probabilities. Weights for the second wave are under development. With these weights, the sample should be representative of the 65+ Japanese population. In fall 1999, 4,997 respondents aged 65+ were interviewed, 74.6 percent of the initial target. Twelve percent of responses were provided by proxies, because of physical or mental health problems. The second wave of data was collected in November 2001. The third wave was collected in November 2003. Questionnaire topics include family structure, and living arrangements; subjects'''' parents/spouse''''s parents/children; socioeconomic status; intergenerational exchange; health behaviors, chronic conditions, physical functioning; activities of daily living and instrumental activities of daily living; functioning in the community; mental health depression measures; vision and hearing; dental health; health care and other service utilization. A CD is available which include the codebook and data files for the first and second waves of the national sample. The third wave of data will be released at a later date. * Dates of Study: 1999-2003 * Study Features: Longitudinal, International * Sample Size: ** 4,997 Nov/Dec 1999 Wave 1 ** 3,992 Nov 2001 Wave 2 ** Nov 2003 Wave 3 Link: * ICPSR: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/00156

Abstract

Sustainable Development Goal (SDG) target 2.1 commits countries to end hunger, ensure access by all people to safe, nutritious and sufficient food all year around. Indicator 2.1.2, “Prevalence of moderate or severe food insecurity based on the Food Insecurity Experience Scale (FIES)”, provides internationally-comparable estimates of the proportion of the population facing difficulties in accessing food. More detailed background information is available at http://www.fao.org/in-action/voices-of-the-hungry/fies/en/ .

The FIES-based indicators are compiled using the FIES survey module, containing 8 questions. Two indicators can be computed:
1. The proportion of the population experiencing moderate or severe food insecurity (SDG indicator 2.1.2), 2. The proportion of the population experiencing severe food insecurity.

These data were collected by FAO through the Gallup World Poll. General information on the methodology can be found here: https://www.gallup.com/178667/gallup-world-poll-work.aspx. National institutions can also collect FIES data by including the FIES survey module in nationally representative surveys.

Microdata can be used to calculate the indicator 2.1.2 at national level. Instructions for computing this indicator are described in the methodological document available in the documentations tab. Disaggregating results at sub-national level is not encouraged because estimates will suffer from substantial sampling and measurement error.

Cleaning operations

Statistical validation assesses the quality of the FIES data collected by testing their consistency with the assumptions of the Rasch model. This analysis involves the interpretation of several statistics that reveal 1) items that do not perform well in a given context, 2) cases with highly erratic response patterns, 3) pairs of items that may be redundant, and 4) the proportion of total variance in the population that is accounted for by the measurement model.

Sampling error estimates

The margin of error is estimated as 3.5. This is calculated around a proportion at the 95% confidence level. The maximum margin of error was calculated assuming a reported percentage of 50% and takes into account the design effect.

Data appraisal

The variable DEGURBA was not considered in the computation of the published FAO food insecurity indicator based on FIES due to the results of the validation process.

Background: Anthropogenic factors potentially affect observed biogeographical patterns in genetic variations of populations, but the effects of ancient human activities on the original patterns that were created by natural processes are unknown. Sinotaia quadrata, a widely distributed freshwater snail species in East Asia, was used to investigate this issue. It is unclear if S. quadrata in Japan was introduced from China, and how different human uses and varying geographic patterns affect the genetic structure of contemporary populations between the two regions. Thus, we investigated the population history of S. quadrata and detected its genetic structure in Japan and continental East Asia.

Results: S. quadrata populations first naturally migrated from continental East Asia to Japan, which is associated with the ancient period in Japanese geohistory (about 70,000 years ago). They were then artificially introduced in association with agriculture expansion by human movements in two recent periods (about 8000 and 1200 years ago). Populations in different parts of Japan have their own sources. Natural migration in the ancient period and artificial introduction in the recent period suggest that the population distribution is affected by both the geohistory of East Asia and the history of human expansion. In the background of the historical migration and introduction, contemporary populations in the two regions show different genetic patterns. Population divergence levels were significantly correlated with geographical patterns in Japan, and significantly correlated with human interventions variables in continental East Asia, suggesting that long-term geographical isolation is likely the major factor that shaped the genetic structure of contemporary populations in Japan, while modern human uses are likely the major factor in continental East Asia.

Conclusions: Our preliminary results show a complex population history and unusual genetic patterns in the contemporary populations for a common freshwater snail and are of significance to determine the historical formation and contemporary patterns of biogeography in Japan and continental East Asia.

Methods This data set is used for population genetics analysis for the freshwater snail, Sinotaia quadrata. Genetic data set is genotyped using 12 microsatellite loci, and divided to three structure files of total, Japan, and (East Asia) continent, respectively. The DIYABC input file contains 237 randomly sampled individuals representing for the four groups in the East Asia continent and Japan. It is used for population history analysis in software DIYABC. The variable data are extracted from WorldClim (http://worldclim.org) and NASA’s Earth Observation system Data and Information System (EOSDIS) (https://sedac.ciesin.columbia.edu).

Japan JP: Prevalence of Stunting: Height for Age: % of Children Under 5, Modeled Estimate data was reported at 5.200 % in 2024. This records an increase from the previous number of 5.100 % for 2023. Japan JP: Prevalence of Stunting: Height for Age: % of Children Under 5, Modeled Estimate data is updated yearly, averaging 6.200 % from Dec 2000 (Median) to 2024, with 25 observations. The data reached an all-time high of 6.900 % in 2009 and a record low of 5.100 % in 2023. Japan JP: Prevalence of Stunting: Height for Age: % of Children Under 5, Modeled Estimate data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Japan – Table JP.World Bank.WDI: Social: Health Statistics. Prevalence of stunting is the percentage of children under age 5 whose height for age is more than two standard deviations below the median for the international reference population ages 0-59 months. For children up to two years old height is measured by recumbent length. For older children height is measured by stature while standing. The data are based on the WHO's 2006 Child Growth Standards.;UNICEF, WHO, World Bank: Joint child Malnutrition Estimates (JME).;Weighted average;Undernourished children have lower resistance to infection and are more likely to die from common childhood ailments such as diarrheal diseases and respiratory infections. Frequent illness saps the nutritional status of those who survive, locking them into a vicious cycle of recurring sickness and faltering growth (UNICEF). Being even mildly underweight increases the risk of death and inhibits cognitive development in children. And it perpetuates the problem across generations, as malnourished women are more likely to have low-birth-weight babies. Stunting, or being below median height for age, is often used as a proxy for multifaceted deprivation and as an indicator of long-term changes in malnutrition. Estimates are modeled estimates produced by the JME. Primary data sources of the anthropometric measurements are national surveys. These surveys are administered sporadically, resulting in sparse data for many countries. Furthermore, the trend of the indicators over time is usually not a straight line and varies by country. Tracking the current level and progress of indicators helps determine if countries are on track to meet certain thresholds, such as those indicated in the SDGs. Thus the JME developed statistical models and produced the modeled estimates.

In 2023, the home ownership rate in Japan stood at 60.9 percent, remaining mostly flat in the past 15 years. That year, the total number of houses owned in the country amounted to approximately 33.9 million. Which type of dwelling is common in Japan? Among all residential buildings in Japan, detached houses exceeded all other building types in numbers. The majority of ordinary Japanese households live in detached houses. Japanese architecture is well known for its traditional wood constructions, and the use of timber for housing construction is still widely spread. Wood is still the major type of structure used for new residential buildings in Japan, followed by materials like steel. The problem of abandoned houses Due to a shrinking and aging population, and rural depopulation, Japan faces an increasing share of vacant dwellings, often referred to as “Akiya”. A large proportion of unoccupied houses in Japan are available for sale or rent. Some local governments and municipalities have reacted to the problem of abandoned houses by offering properties at reduced prices or even for free on certain conditions.
