Key information about Japan population

• The Japan population reached 123.7 million people in Dec 2024, compared with the previously reported figure of 124.3 million people in Dec 2023
• The data reached an all-time high of 128.1 million people in Dec 2010 and a record low of 43.4 million people in Dec 1899

• In the latest reports, Japan Unemployment Rate increased to 2.5 % in Oct 2024
• Monthly earnings of the Japan population was 1,957.4 USD in Oct 2024
• Japan Labour Force Participation Rate remained the same rate at 63.5 % in Oct 2024

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.

In 2023, women made up about **** percent of centenarians in Japan, indicating that the vast majority of people aged 100 years and older in the country were female. The share of women among centenarians peaked in the previous year at **** percent.

The number of mobile cellular subscriptions per 100 inhabitants in Japan has grown rapidly since 2000, reaching from roughly ** to above 100 by 2011. The number continued to grow, peaking in the most recent year of 2023 at approximately *** mobile cellular subscriptions for every 100 people in the country.

This statistic presents the results of a survey on the perceived percentage of population over 65 years old by 2050 in Japan as of 2018. According to data published by Ipsos, Japanese respondents overestimated the proportion of their population who will be over ** in 2050. On average, the respondents thought that around ** out of every 100 people in Japan will be over 65 years old in 2050, when the actual share of elderly population, according to projections by the World Bank, will be around ** percent in Japan.

Japan Population Census: Male: Age 100 to 104 Years data was reported at 8,383.000 Person in 2015. This records an increase from the previous number of 5,851.000 Person for 2010.

The data is categorized under Global Database’s Japan – Table JP.G002: Population: Annual.

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.

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

There were 61 300 900 Facebook users in Japan in April 2023, which accounted for 49.2% of its entire population. The majority of them were women - 53.3%. People aged 18 to 24 were the largest user group (14 100 000). The highest difference between men and women occurs within people aged 25 to 34, where women lead by 6 000 000.

The fertility rate of a country is the average number of children that women from that country will have throughout their reproductive years. From 1800 until 1865, Japan's fertility rate grew quite gradually, from 4.1 children per woman, to 4.8. From this point the fertility rate drops to 3.6 over the next ten years, as Japan became more industrialized. Towards the end of the nineteenth century, Japan's fertility rate grew again, and reached it's highest recorded point in the early 1920s, where it was 5.4 children per woman. Since this point it has been gradually decreasing until now, although it did experience slight increases after the Second World War, and in the early 1970s. In recent decades Japan's population has aged extensively, and today, Japan has the second oldest population and second highest life expectancy in the world (after Monaco). In contrast to this, Japan has a very low birth rate, and it's fertility rate is expected to fall below 1.4 children per woman in 2020.
