Demographics
Japan has a population of almost 125 million, of which nearly 122 million are Japanese nationals (2022 estimates). A small population of foreign residents makes up the remainder. In 2019, 92% of the total Japanese population lived in cities. The capital city Tokyo has a population of 13.9 million (2022). It is part of the Greater Tokyo Area, the biggest metropolitan area in the world with 38,140,000 people (2016). Japan is an ethnically and culturally homogeneous society, the Japanese people form 98.1% of the country's population. Minority ethnic groups in the country include the indigenous Ainu and Ryukyuan people. Zainichi Koreans, Chinese, Filipinos, Brazilians mostly of Japanese descent, and Peruvians mostly of Japanese descent are also among Japan's small minority groups. Burakumin make up a social minority group.Japan is the world's fastest aging country and has the highest proportion of elderly citizens of any country, comprising one-third of its total population; this is the result of a post–World War II baby boom, which was followed by an increase in life expectancy and a decrease in birth rates. Japan has a total fertility rate of 1.4, which is below the replacement rate of 2.1, and is among the world's lowest; it has a median age of 48.4, the highest in the world. As of 2020, over 28.7 percent of the population is over 65, or more than one in four out of the Japanese population. As a growing number of younger Japanese are not marrying or remaining childless, Japan's population is expected to drop to around 88 million by 2065.The changes in demographic structure have created several social issues, particularly a decline in the workforce population and an increase in the cost of social security benefits. The Government of Japan projects that there will be almost one elderly person for each person of working age by 2060. Immigration and birth incentives are sometimes suggested as a solution to provide younger workers to support the nation's aging population. On April 1, 2019, Japan's revised immigration law was enacted, protecting the rights of foreign workers to help reduce labor shortages in certain sectors.
