Demographics of Japan - statistics & facts
While there is a range of factors determining the demographics of a country, Japan鈥檚 most prominent feature is its population development and age structure. Following high growth rates in the late 19th and early 20th century, population growth started slowing down after World War II. The population eventually reached its peak with more than 128 million people between 2007 and 2010. Low birthrate, as well as low levels of immigration, have led to a declining trend since then. Despite the decreasing number of inhabitants, the population density in Japan remains one of the highest in Asia. The population is highly concentrated in metropolitan areas, most notably Tokyo, which is one of the world鈥檚 most populated cities, as well as Osaka and Nagoya. While many rural areas face depopulation tendencies, land prices in the three large metropolitan areas have been increasing since the mid-2010s.聽
Aging population
Japan鈥檚 population is currently not only shrinking, it is also one of the fastest aging populations in the world. At the same time, it has one of the highest life expectancies. The cohort of people aged 65 years and older consisted of around 36.5 million people in 2025 and was estimated to make up almost 39 percent of the population by 2070.
Due to those demographic changes, the Japanese economy today faces severe labor shortages, as is exemplified by a comparably low unemployment rate. Until recently, the workforce in Japan was shrinking rapidly, putting pressure on the social security system. But continued employment of the elderly and the growing integration of women into the labor market have kept the labor force relatively stable and even led to a slight increase in recent years.
Immigration as a growing counterweight
The population in Japan appears largely homogenous compared to many other countries around the world. Yamato people, a term used since the 19th century for the ethnic group native to the Japanese archipelago to distinguish them from minority groups, such as Ainu, Ryukyuans, or Koreans and Taiwanese who had settled in peripheral areas of Japan, make up the overwhelming majority of the population. However, the number of foreign residents living in Japan has grown sharply in recent years,. As this group consists largely of younger people, it is expected to play a growing role in sustaining Japan's workforce at a time when the country's total fertility rate has dropped to a record low.
