Approximately 36.5 million people in Japan were estimated to be within the age group 65 and over in 2024. This number was projected to increase until 2040 and then decline to about 20.1 million by 2120.

The statistic shows the total population in Japan from 2020 to 2024, with projections up until 2030. In 2024, the total population of Japan amounted to around 123.89 million inhabitants. See the figures for the population of South Korea for comparison. Total population in Japan From steadily low fertility rates to a growing elderly population, it is no secret that Japan’s population is shrinking. Population growth rates jump around a little, but are currently following a declining trend. The post-war baby boom generation is now in the 65-and-over age group, and the percentage of the population in that category is expected to keep growing, as is indicated by a high median age and high life expectancy. Japan already has the highest percentage of its population over 65 in the world, and the aging population puts some pressure on the Japanese government to provide welfare services for more people as rising numbers leave the workforce. However, the amount of jobs opened up for the younger generations by the older generations leaving the workforce means that unemployment is kept to a minimum. Despite a jump in unemployment after the global recession hit in 2008, rates were almost back to pre-recession rates by 2013. Another factor affecting Japan is the number of emigrants to other countries. The United States absorbs a number of emigrants worldwide, so despite a stagnating birth rate, the U.S. has seen a steady rise in population.

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.

The median age of the population in Japan has steadily been increasing since 1950 and is projected to be around 47.7 years old in 2020. As of 2021, the median age of Japan is the second highest in the world, behind the Principality of Monaco. The elderly in Japan An improved quality of life and regular health checks are just two reasons why Japan has one of the highest life expectancies in the world. The life expectancy from birth in Japan improved significantly after World War II, rising 20 years in the decade between 1945 and 1955. As life expectancy continues to increase, Japan expects difficulties caring for the older generation in the future. Shortages in the service sector are already a major concern, with demand for nurses and care workers increasing. Fertility and birth rates The fertility rate among Japan’s population has been around 1.4 children per woman since 2010. Apart from a small baby boom in the early seventies, the crude birth rate of Japan has been declining since 1950 and is expected to be as low as 7.5 births per thousand people in 2020. With falling birth rates and such a large share of its inhabitants reaching their later years, Japan’s total population is expected to continue declining.

The total population in Japan was estimated at 123.6 million people in 2024, according to the latest census figures and projections from Trading Economics. This dataset provides - Japan Population - actual values, historical data, forecast, chart, statistics, economic calendar and news.

Tokyo Prefecture continued to be a magnet for domestic migration in Japan, attracting nearly 58,500 new residents from other prefectures in 2023. By contrast, Hiroshima Prefecture showed the highest population loss due to outbound migration within the country, with a net loss of approximately 7,400 migrants. Attractiveness of Tokyo The population density in the prefecture has grown over the past two decades, surpassing 6,400 inhabitants per square kilometer in 2020. The appealing nature of Tokyo is also reflected in the age demographics of the metropolis, with most residents falling within the working-age group of 15 to 64 years. Numerous prestigious universities and large corporations make the area a popular destination for young people with aspirations. Depopulation of rural areas The migration patterns across Japan's prefectures indicate significant regional disparities. While Tokyo leads in population size with 14 million inhabitants in 2023, prefectures like Tottori struggle to retain residents, counting only about 540,000 people. This imbalance has prompted concerns about the sustainability of rural communities and has led to various initiatives aimed at revitalizing less populous areas. The Japanese government faces the complex task of addressing these demographic shifts while also navigating challenges resulting from a nationwide aging population due to prolonged life expectancy and fertility decline.

In 2023, around 29.1 percent of the total population in Japan was aged 65 years and older. Due to a low birth rate and high longevity, people aged 65 years and over were estimated to make up approximately 38.7 percent of the population in Japan by 2070. The share of children below 15 years old was expected to decrease to around 9.2 percent by that year.

In 2024, around **** percent of the male population and **** percent of the female population aged 15 years and above in Japan were in the workforce nationally. The labor force participation rate among women reached the highest share since 1973. Female employment rate Japan’s employment rate, the share of people who are employed among the total population aged 15 years and above, rose to **** percent in the same year. It was mainly a higher share of ***** in employment that contributed to the overall increase in the employment rate in 2024. Despite the female employment rate reaching an all-time high, a significantly larger share of women, over **** of female employees, were in non-regular employment, such as part-time and temporary work. Distinctive work patterns of women shaped by Japan’s labor market and corporate culture are one of the reasons for its gender gap when it comes to equal economic participation. Women’s work patterns One of these work patterns is the M-shaped curve of female labor participation. The curve reflects the trend that female labor force participation peaks in the age group of ** to **-year-olds and then falls, as women drop out of the workforce upon life events such as marriage and childbirth, only to reenter the workforce at a later stage. This curve has gradually flattened in recent years, as fewer women left the workforce in their ********. However, the so-called L-shaped curve of women in regular employment suggests that instead, fewer women stay in regular employment. The percentage of women working in regular full-time jobs peaks in the age bracket of ** to **-year-olds and then declines steadily. This makes women less likely to enter leadership positions.

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.

In 2023, there were around *** live births per 1,000 inhabitants in Japan, down from about *** in the previous year. The total number of live births in the nation amounted to approximately ******* in 2023. Japan’s super aging society Directly after the end of WWII, the live birth rate in Japan was over ** per 1,000 of population. The rate has constantly dropped in the last decades after the second baby boom (between 1971 and 1974). Meanwhile, the life expectancy of the Japanese people has increased, reaching about **** years for women and **** years for men in 2022. Due to the combination of both factors, Japan has developed into one of the most rapidly aging societies in the world. Almost ** percent of Japan’s population is currently aged 65 years and older, falling into the “super-aged nation” defined by international institutions and organizations.  Decreasing number of marriages In Japan, the number of births outside of marriage is small. The Japanese government, therefore, considers the decreasing number of marriages as the driving factor behind the country’s fertility decline. As of 2023, the number of marriages per 1,000 Japanese citizens was ***, less than half compared to that in the early *****. The average age of first marriage has also risen for both men and women. This trend can be partially attributed to the increasing number of employed and therefore financially and socially independent women in the past two decades. The employment rate of women in Japan exceeded ** percent for the first time in history in ****.

BackgroundKawasaki disease (KD) is a common cause of acquired paediatric heart disease in developed countries. KD was first identified in the 1960s in Japan, and has been steadily increasing since it was first reported. The aetiology of KD has not been defined, but is assumed to be infection-related. The present study sought to identify the factor(s) that mediate the geographical variation and chronological increase of KD in Japan.Methods and FindingsBased upon data reported between 1979 and 2010 from all 47 prefectures in Japan, the incidence and mean patient age at the onset of KD were estimated. Using spatial and time-series analyses, incidence and mean age were regressed against climatic/socioeconomic variables. Both incidence and mean age of KD were inversely correlated with the total fertility rate (TFR; i.e., the number of children that would be born to one woman). The extrapolation of a time-series regressive model suggested that KD emerged in the 1960s because of a dramatic decrease in TFR in the 1940s through the 1950s.ConclusionsMean patient age is an inverse surrogate for the hazard of contracting the aetiologic agent. Therefore, the observed negative correlation between mean patient age and TFR suggests that a higher TFR is associated with KD transmission. This relationship may be because a higher TFR facilitates sibling-to-sibling transmission. Additionally, the observed inverse correlation between incidence and TFR implies a paradoxical “negative” correlation between the incidence and the hazard of contracting the aetiologic agent. It was hypothesized that a decreasing TFR resulted in a reduced hazard of contracting the agent for KD, thereby increasing KD incidence.
