Japan’s largest city, greater Tokyo, had a staggering ***** million inhabitants in 2023, making it the most populous city across the Asia-Pacific region. India had the second largest city after Japan with a population consisting of approximately ** million inhabitants. Contrastingly, approximately *** thousand inhabitants populated Papua New Guinea's largest city in 2023. A megacity regionNot only did Japan and India have the largest cities throughout the Asia-Pacific region but they were among the three most populated cities worldwide in 2023. Interestingly, over half on the world’s megacities were situated in the Asia-Pacific region. However, being home to more than half of the world’s population, it does not seem surprising that by 2025 it is expected that more than two thirds of the megacities across the globe will be located in the Asia Pacific region. Other megacities are also expected to emerge within the Asia-Pacific region throughout the next decade. There have even been suggestions that Indonesia’s Jakarta and its conurbation will overtake Greater Tokyo in terms of population size by 2030. Increasing populationsIncreased populations in megacities can be down to increased economic activity. As more countries across the Asia-Pacific region have made the transition from agriculture to industry, the population has adjusted accordingly. Thus, more regions have experienced higher shares of urban populations. However, as many cities such as Beijing, Shanghai, and Seoul have an aging population, this may have an impact on their future population sizes, with these Asian regions estimated to have significant shares of the population being over 65 years old by 2035.

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.

As of 2025, Guangzhou had the largest metropolitan population in the Asia-Pacific region, with approximately **** million inhabitants. Tokyo had the second-largest metropolitan population of around **** million inhabitants. There were a total of ** megacities with a population of over 10 million inhabitants in the Asia-Pacific region as of 2025.

As of January 2025, Hangzhou in China had the highest annual metropolitan population growth rate among megacities in the Asia-Pacific region, at about **** percent. In contrast, all three Japanese megacities—Tokyo, Nagoya, and Osaka—had the lowest annual population growth rates across APAC, with Osaka's population shrinking by ***** percent as of January 2025.

With approximately **** million inhabitants, Tokyo was Japan's most populous city as of 2023, followed by Yokohama, which, in the same year, counted about **** million inhabitants. In total, there were twelve cities with a population of over one million people in Japan.

As of January 2024, more than ******* residents from China were registered in Tokyo Prefecture, accounting for the largest share of foreign nationals. The second-largest group of foreign nationals living in the prefecture were from South Korea.

In 2025, the degree of urbanization worldwide was at 58 percent. North America, Latin America, and the Caribbean were the regions with the highest level of urbanization, with over four-fifths of the population residing in urban areas. The degree of urbanization defines the share of the population living in areas defined as "cities". On the other hand, less than half of Africa's population lives in urban settlements. Globally, China accounts for over one-quarter of the built-up areas of more than 500,000 inhabitants. The definition of a city differs across various world regions - some countries count settlements with 100 houses or more as urban, while others only include the capital of a country or provincial capitals in their count. Largest agglomerations worldwideThough North America is the most urbanized continent, no U.S. city was among the top ten urban agglomerations worldwide in 2023. Tokyo-Yokohama in Japan was the largest urban area in the world that year, with 37.7 million inhabitants. New York ranked 13th, with 21.4 million inhabitants. Eight of the 10 most populous cities are located in Asia. ConnectivityIt may be hard to imagine how the reality will look in 2050, with 70 percent of the global population living in cities, but some statistics illustrate the ways urban living differs from suburban and rural living. American urbanites may lead more “connected” (i.e., internet-connected) lives than their rural and/or suburban counterparts. As of 2021, around 89 percent of people living in urban areas owned a smartphone. Internet usage was also higher in cities than in rural areas. On the other hand, rural areas always have, and always will, attract those who want to escape the rush of the city.

In 2024, the gross total floor area of new large-scale office buildings in Tokyo’s 23 wards amounted to approximately ******* square meters. The supply volume of new office space was forecasted to increase to **** million square meters in 2025. Tokyo Metropolis Tokyo Metropolis is Japan’s largest city, with a population of more than **** million inhabitants. It consists of 23 special wards and over 30 towns, cities, and villages. The five wards of Chuo, Shibuya, Shinjuku, Minato, and Chiyoda form Tokyo’s central business district. These districts boast the highest average land prices and rents for office space in the city. Tokyo is the leading office market in Japan, and a large proportion of office buildings are concentrated there. Office buildings in Tokyo The floor space of office buildings with a floor size of 100 tsubo or more in the central business districts of Tokyo reached over ** million tsubo in 2024, equal to about **** square kilometers. Most of the existing office building stock in Tokyo was completed between the 1980s and 1990s. During this time, Japan experienced an asset price bubble that led to a real estate development boom. Some major office construction projects in Tokyo are scheduled to be completed in the coming years. ***********, for example, will become Japan's tallest building, with a height of *** meters, upon its completion in 2028.

In Japan, the population sex ratio has seen slight changes over the past decades. In 2021, the number of men was around **** for every 100 women, constituting a decrease from **** in 1950.

What is the sex ratio? The population sex ratio is determined by the sex ratio at birth, different mortality rates between men and women, as well as losses and gains through migration. In the absence of alteration, the sex ratio in human populations is quite constant, with only minor deviations. While the sex ratio at birth is usually *** to ***, the population sex ratio, which refers to the total number of males for every 100 females, is often below 100. The reason for the shift mostly lies in differing lifestyles and physical constitutions of men and women. In general, women tend to be more resistant to disease throughout life, while men tend to engage in higher risk behavior or violence.

Influences and consequences
The sex ratio at birth and its possible determinants such as gestation environment, climate change, chemical pollution or socio-economic factors have long been subject to scientific research. Recently the impact of natural disasters, like the nuclear disaster in Japan in 2011, was presumed to influence the sex ratio at birth. The adult gender ratio has long been recognized as a key population-level determinant of behavior. However, there are many different or competing theories in existing literature about the social impacts of gender imbalance on topics such as violence, family stability, reproduction etc.

Japan’s geography The Japanese archipelago consists of the five main islands of Honshu, Hokkaido, Kyushu, Shikoku, and Okinawa in addition to thousands of smaller islands. Together, they cover a surface area of around ******* square kilometers. ************** of the country’s land area is covered by mountains. Forestland and farmland constitute about ** percent of its landmass, while developed land accounts for **** percent. The population of *** million is concentrated in major cities like Tokyo, which is home to over **** million inhabitants. Urban-rural divide and land prices Owing to an overconcentration of economic activity in Tokyo and other major cities like Osaka and Nagoya, more than half of the population is located in ***** metropolitan areas. Tokyo and its surrounding prefectures that comprise the Tokyo metropolitan area attract many people from other parts of the country each year, often young individuals seeking jobs or starting university. In contrast, rural regions are confronted with depopulation and economic stagnation. Japan’s urban-rural divide is also reflected in land prices. Tokyo has by far the most expensive land prices. In terms of land price growth, the cities of Sapporo, Sendai, Hiroshima, and Fukuoka have outpaced the Greater Tokyo Area in the past decade.
