Census

Japan collects census information every five years, with censuses conducted by the Statistics Bureau of the Ministry of Internal Affairs.^[20][21] The latest population census reflects the situation as of 2020.^[21]

Population density

Japan's population density was 336 people per square kilometer as of 2014 (874 people per square mile) according to World Development Indicators. It ranks 35th in a list of countries by population density. Between 1955 and 1989, land prices in the six largest cities increased by 15,000% (+12% per year compound). Urban land prices generally increased 40% from 1980 to 1987; in the six largest cities, the price of land doubled over that period. For many families, this trend put housing in central cities out of reach.^[11]

The result was lengthy commutes for many workers in the big cities, especially in the Tokyo area where daily commutes of two hours each way are common.^[11] In 1991, as the bubble economy started to collapse, land prices began a steep decline, and within a few years fell 60% below their peak.^[22] After a decade of declining land prices, residents began moving back into central city areas (especially Tokyo's 23 wards), as evidenced by 2005 census figures. Despite nearly 70% of Japan being covered by forests,^[23] parks in many major cities—especially Tokyo and Osaka—are smaller and scarcer than in major West European or North American cities. As of 2014, parkland per inhabitant in Tokyo is 5.78 square meters,^[24] which is roughly half of the 11.5 square meters of Madrid.^[25]

National and regional governments devote resources to making regional cities and rural areas more attractive by developing transportation networks, social services, industry, and educational institutions to try to decentralize settlement and improve the quality of life. Nevertheless, major cities, especially Tokyo, Yokohama and Fukuoka, and to a lesser extent Kyoto, Osaka and Nagoya, remain attractive to young people seeking education and jobs.^[11]

Japan has a high population concentration in urban areas on the plains since 75% of Japan's land area is made up of mountains,^[27] and also Japan has a forest cover rate of 68.5% (the only other developed countries with such a high forest cover percentage are Finland and Sweden).^[23] The 2010 census shows 90.7% of the total Japanese population live in cities.^[28]

Japan is an urban society with about only 5% of the labor force working in agriculture. Many farmers supplement their income with part-time jobs in nearby towns and cities. About 80 million of the urban population is heavily concentrated on the Pacific shore of Honshu.^[29]

Metropolitan Tokyo-Yokohama, with its population of 35 million residents, is the world's most populous city. Japan faces the same problems that confront urban industrialized societies throughout the world: overcrowded cities and congested highways.

Age structure

Japan's population is aging faster than that of any other nation.^[30] The population of those 65 years or older roughly doubled in 24 years, from 7.1% of the population in 1970 to 14.1% in 1994. The same increase took 61 years in Italy, 85 years in Sweden, and 115 years in France.^[31] In 2014, 26% of Japan's population was estimated to be 65 years or older,^[32] and the Health and Welfare Ministry has estimated that over-65s will account for 40% of the population by 2060.^[33] The demographic shift in Japan's age profile has triggered concerns about the nation's economic future and the viability of its welfare state.^[34]

Fertility

As of 2022, Japan's total fertility rate was 1.26, among the lowest in the world and far below the replacement rate of 2.1. Japanese Prime Minister Fumio Kishida has pledged to take urgent steps to tackle the country's declining birth rate, calling it "now or never" for Japan's aging society, and plans to double the budget for child-related policies by June and set up a new government agency in April.^{[citation needed]}

Internal migration

Between 6 million and 7 million people moved their residences each year during the 1980s. About 50% of these moves were within the same prefecture; the others were relocations from one prefecture to another. During Japan's economic development in the twentieth century, and especially during the 1950s and 1960s, migration was characterized by urbanization as people from rural areas in increasing numbers moved to the larger metropolitan areas in search of better jobs and education. Out-migration from rural prefectures continued in the late 1980s, but more slowly than in previous decades.^[11]

In the 1980s, government policy provided support for new urban development away from the large cities, particularly Tokyo, and assisted regional cities to attract young people to live and work there. Regional cities offered familiarity to those from nearby areas, lower costs of living, shorter commutes, and, in general, a more relaxed lifestyle than could be had in larger cities. Young people continued to move to large cities, however, to attend universities and find work, but some returned to regional cities (a pattern known as U-turn) or to their prefecture of origin (referred to as "J-turn"), or even moved to a rural area for the first time ("I-turn").^[11][45]

Government statistics show that in the 1980s significant numbers of people left the largest central cities (Tokyo and Osaka) to move to suburbs within their metropolitan areas. In 1988, more than 500,000 people left Tokyo, which experienced a net loss through migration of nearly 73,000 for the year. Osaka had a net loss of nearly 36,000 in the same year.^[11]

With a decreasing total population, internal migration results in only eight prefectures showing an increase in population. These are Okinawa (2.9%), Tokyo (2.7%), Aichi (1.0%), Saitama (1.0%), Kanagawa (0.9%), Fukuoka (0.6%), Shiga (0.2%), and Chiba (0.1%).^[46]

Emigration

About 663,300 Japanese were living abroad, approximately 75,000 of whom had permanent foreign residency, more than six times the number who had that status in 1975. More than 200,000 Japanese went abroad in 1990 for extended periods of study, research, or business assignments. As the government and private corporations have stressed internationalization, greater numbers of individuals have been directly affected, decreasing Japan's historical insularity. By the late 1980s, these problems, particularly the bullying of returnee children in schools, had become a major public issue both in Japan and in Japanese communities abroad.^[11]

Cities with significant populations of Japanese nationals in 2015 included:

• Los Angeles, United States: 68,689
• Bangkok, Thailand: 48,700
• Shanghai, China: 46,115
• New York, United States: 44,636
• Singapore: 36,963
• London, United Kingdom: 36,721
• Sydney, Australia: 30,448
• Vancouver, Canada: 26,999
• Hong Kong: 26,869
• San Francisco, United States: 18,777
• Toronto, Canada: 13,410

Note: The above data shows the number of Japanese nationals living overseas. It was published by the Ministry of Foreign Affairs of Japan and relates to 2015.^[47]

Immigration

According to the Japanese immigration centre, the number of foreign residents in Japan has steadily increased, and the number of foreign residents exceeded 2.8 million people in 2020.^[48]

In 2020, the number of foreigners in Japan was 2,887,116. This includes 325,000 Filipinos, many of whom are married to Japanese nationals and possessing some degree of Japanese ancestry,^[49][50] 208,538 Brazilians, the majority possessing some degree of Japanese ancestry,^[50] 778,112 Chinese, 448,053 Vietnamese and 426,908 South Koreans. Chinese, Vietnamese, Koreans, Filipinos and Brazilians account for about 77% of foreign residents in Japan.

The current issue of the shrinking workforce in Japan alongside its aging population has resulted in a recent need to attract foreign labour to the country. Reforms which took effect in 2015 relax visa requirements for "Highly Skilled Foreign Professionals" and create a new type of residence status with an unlimited period of stay.

The number of naturalizations peaked in 2008 at 16,000, declining to over 9,000 in the most recent year for which data are available.^[51] Most of the decline is accounted for by a steep reduction in the number of Japan-born Koreans taking Japanese citizenship. Historically the bulk of those taking Japanese citizenship have not been foreign-born immigrants but rather Japanese-born descendants of Koreans and Taiwanese who lost their citizenship in the Japanese Empire in 1947 as part of the American Occupation policy for Japan.

Japanese statistical authorities do not collect information on ethnicity, only nationality.^[52] As a result, both native and naturalized Japanese citizens are counted in a single group.^[53] Although official statistics therefore show homogeneity, other analyses describe the population as “multi-ethnic”.^[54][55][56]

Lifestyle

Japanese people enjoy a high standard of living, and nearly 90% of the population consider themselves part of the middle class.^[11] However, many studies on happiness and satisfaction with life tend to find that Japanese people average relatively low levels of life satisfaction and happiness when compared with most of the highly developed world; the levels have remained consistent if not declining slightly over the last half century.^{[62][63][64][65]} Japanese have been surveyed to be relatively lacking in financial satisfaction.^[66] The societal view generally disapproves of out-of-wedlock births and premarital pregnancies.^[67]

Social isolation is a problem for a segment of Japanese society, with almost 500,000 young people belonging to this group, they are also known as hikikomori.^[68]

The Japanese management working culture in Japan has led some to work-related deaths due to heart attack or stroke, this has led to the term karoshi (lit. "overwork death"). The government has received 200 claims of karoshi related work injuries each year, with some leading to suicide.^[69]

Many Japanese lead a sexless marriage. Japan has the lowest level of couples having sex at 45 times per year, well below the global average of 103 times. With reasons of "tired" and "bored with intercourse" usually given as an answer.^[70] Despite this, Japan ranks as number two globally on the amount spent on pornography, after South Korea.^[71][72]

Discrimination against ethnic minorities

Three native Japanese minority groups can be identified. The largest are the hisabetsu buraku or "discriminated communities", also known as the burakumin. These descendants of premodern outcast hereditary occupational groups, such as butchers, leatherworkers, funeral directors, and certain entertainers, may be considered a Japanese analog of India's Dalits. Historically, discrimination against these occupational groups was based on Buddhist prohibitions on killing and Shinto notions of pollution, and it was also a feature of governmental attempts to maintain social control.^[11]

During the Edo period, such people were required to live in special buraku and, like the rest of the population, they were bound by sumptuary laws which were based on the inheritance of social class. The Meiji government abolished most of the derogatory names which were applied to these discriminated communities in 1871, but the new laws had little effect on the social discrimination which was faced by the former outcasts and their descendants. However, the laws eliminated the economic monopoly which they had on certain occupations.^[11] The buraku continued to be treated as social outcasts and some casual interactions with the majority caste were perceived taboo until the era after World War II.

Estimates of their number range from 2 to 4 million (about 4% of the national population in 2022). Although the members of these marginalized communities are physically indistinguishable from other Japanese, most of them live in urban ghettoes or they live in the traditional special hamlets which are located in rural areas, and as a result, membership in a marginalized group can be surmised from the location of a family's home, a family's occupation, the dialect which a family speaks, or the mannerisms which a family uses when it communicates with people. Checks on the backgrounds of families which were designed to ferret out buraku were commonly performed as a condition of marriage arrangements and employment applications,^[11] but in Osaka, they have been illegal since 1985.

Among the hisabetsu buraku, past and current discrimination against them has resulted in lower educational attainments and it has also resulted in a lower socioeconomic status, by contrast, the majority of Japanese have higher educational attainments and they also have a higher economic status. Movements with objectives which range from "liberation" to the encouragement of integration have attempted to change this situation,^[11] with some success. Nadamoto Masahisa of the Buraku History Institute estimates that as of 1998, between 60 and 80% of burakumin marry a non-burakumin.^[73]

Ryukyuans

One of the largest minority groups among Japanese citizens is the Ryukyuan people.^[74] They are primarily distinguished by their use of several distinct Ryukyuan languages, though use of Ryukyuan is dying out.^[75] The Ryukyuan people and language originated in the Ryukyu Islands, which are in Okinawa prefecture and Kagoshima Prefecture.

Ainu

The third largest minority group among Japanese citizens is the Ainu, whose language is an isolate. Historically, the Ainu were an indigenous hunting and gathering population who occupied most of northern Honshū as late as the Nara period (A.D. 710–94). As Japanese settlement expanded, the Ainu were pushed northward,^[11] by the Tokugawa shogunate, the Ainu were pushed into the island of Hokkaido.^[76]

Characterized as remnants of a primitive circumpolar culture, the fewer than 20,000 Ainu in 1990 were considered racially distinct and thus not fully Japanese. Disease and a low birth rate had severely diminished their numbers over the past two centuries, and intermarriage had brought about an almost completely mixed population.^[11]

Although no longer in daily use, the Ainu language is preserved in epics, songs, and stories transmitted orally over succeeding generations. Distinctive rhythmic music and dances and some Ainu festivals and crafts are preserved, but mainly in order to take advantage of tourism.^[11]

Hāfu

Hāfu (a kana rendition of "half") is a term used for people who are biracial and ethnically half Japanese. Of the one million children born in Japan in 2013, 2.2% had one or two non-Japanese parents.^[70] According to the Japanese Ministry of Health, Labor and Welfare, one in forty-nine babies born in Japan today are born into families with one non-Japanese parent.^[77] Most intermarriages in Japan are between Japanese men and women from other Asian countries, including China, the Philippines and South Korea.^[78] Southeast Asia too, also has significant populations of people with half-Japanese ancestry, particularly in the Philippines, Indonesia, Malaysia, Singapore and Thailand.

In the 1940s, biracial Japanese children (Ainoko), specifically Amerasian children, encountered social problems such as poverty, perception of impurity and discrimination due to negative treatment in Japan.^[79] In the 21st century, discrimination against hāfu occurs based on how different their identity, behavior and appearance is from a typical Japanese person.^[80]

Foreign residents as of 2015

There was an increase of 110,358 foreign residents from 2014 to 2015. Vietnamese made the largest proportion of these new foreign residents, whilst Nepalese, Filipino, Chinese and Taiwanese are also significant in numbers. Together these countries makes up 91,126 or 82.6% of all new residents from 2014 to 2015. However, the majority of these immigrants will only remain in Japan for a maximum of five years, as many of them have entered the country in order to complete trainee programmes. Once they complete their programmes, they will be required to return to their home countries.^[102]

As of December 2014 there were 2,121,831 foreigners residing in Japan, 677,019 of whom were long-term residents in Japan, according to national demographics figures. The majority of long-term residents were from Asia, totalling 478,953. Chinese made up the largest portion of them with 215,155, followed by Filipinos with 115,857, and Koreans with 65,711. Thai, Vietnamese, and Taiwanese long-term residents totaled 47,956, and those from other Asian countries totaled 34,274. The Korean figures do not include zainichi Koreans with tokubetsu eijusha ("special permanent resident") visas, of whom there were 354,503 (of a total of 358,409 of all nationalities with such visas). The total number of permanent residents had declined over the previous five years due to high cost of living.^[95]

Foreign residents as of 2021

The number of foreign residents of Japan reached a high of 2.93 million in 2019 before falling to 2.76 million at the end of 2021.^[103] The number of foreign workers was 1.46 million in 2018, 29.7% are in the manufacturing sector; 389,000 are from Vietnam and 316,000 are from China.^[104]

On April 1, 2019, Japan's revised immigration law was enacted. The revision clarifies and better protects the rights of foreign workers. Japan formally accepts foreign blue-collar workers. This helps reduce labour shortage in certain sectors of the economy. The reform changes the status of foreign workers to regular employees and they can obtain permanent residence status. The reform includes a new visa status called tokutei gino (特定技能, "designated skills"). In order to qualify, applicants must pass a language and skills test (level N4 or higher of the Japanese-Language Proficiency Test). In the old "Technical Trainee programme" a foreign employee was tied to their employer. This caused numerous cases of exploitation. The revision gives foreign workers more freedom to leave and change their employer.^[105]
