Why is Japan population decline?


Japan has been experiencing a population decline since the 1970s, with projections estimating that by 2060, the population will have decreased by 40%. This phenomenon is caused by a combination of factors, including an aging population, low fertility rates, and a lack of immigration. In this article, we will explore the reasons behind Japan’s population decline in detail.

Aging Population

Japan has one of the oldest populations in the world, with a median age of 47 years. The aging population is due to a combination of factors, including increased life expectancy and low fertility rates. The older population also means that there are fewer people of working age to support the economy.

Low Fertility Rates

Japan has one of the lowest fertility rates in the world, with an average of only 1.4 children per woman. This is due to a combination of factors, including high education and career expectations for women, a lack of family-friendly policies in the workplace, and cultural attitudes towards marriage and parenthood.

Lack of Immigration

Japan has historically been a relatively closed society, with limited immigration policies. This has led to a lack of diversity in the population and a shortage of workers in certain industries. While there have been recent efforts to increase immigration, it remains a contentious issue in Japanese society.

Economic Challenges

The aging population and low fertility rates present significant economic challenges for Japan. The labor force is shrinking, which makes it difficult for businesses to find workers. There is also a strain on social security systems as more people retire and require support.

Gender Inequality

Japan has long struggled with gender inequality, particularly in the workplace. Women are often paid less than men for doing the same job and are underrepresented in leadership positions. This has led to a lack of support for working mothers and a reluctance to have children.

High Cost of Living

The cost of living in Japan is notoriously high, particularly in large cities like Tokyo. The high cost of housing, education, and healthcare can make it difficult for young people to start families and afford to raise children.

Declining Marriage Rates

Marriage rates in Japan have been declining for decades, with many young people choosing to remain single or delay marriage. This is due to a combination of factors, including economic challenges, changing societal attitudes towards traditional gender roles, and a lack of interest in marriage among younger generations.


Japan has one of the highest rates of urbanization in the world, with over 90% of the population living in cities. This has led to a decline in rural communities and a concentration of resources in urban areas. The lack of opportunities in rural areas can make it difficult for young people to stay and start families.

Work Culture

Japan’s work culture is notoriously intense, with long hours and a focus on productivity over work-life balance. This can make it difficult for employees to find time for family and personal life, particularly for women who are often expected to prioritize their careers over starting families.

Education System

The education system in Japan is highly competitive, with a focus on academic achievement over creativity and personal development. This can lead to high levels of stress among students and a reluctance to start families due to concerns about balancing education and parenthood.

Government Policies

The Japanese government has implemented various policies in an attempt to address the population decline, including subsidies for childcare and incentives for companies to hire more women. However, these policies have had limited success due to cultural attitudes towards parenthood and gender roles.


Japan’s population decline is a complex issue with no easy solutions. While there have been recent efforts to address the problem, including increased immigration and family-friendly policies, there is still a long way to go. The aging population and low fertility rates present significant economic challenges for Japan, and it will require a concerted effort from government, businesses, and society as a whole to address these issues and ensure a sustainable future.

What is the main problem with Japan’s population?

In 2021, Japan experienced a historic decrease in the number of births, resulting in the largest natural population decline ever recorded. Additionally, approximately 28% of the population in Japan is over the age of 65, contributing to this issue. This information was reported as of January 23rd, 2023.

Is Japan’s birth rate declining?

Japan is experiencing a significant demographic crisis, with the annual number of births falling below 800,000 for the first time in 2022. The current birth rate of 1.34 is below the 2.07 rate needed to maintain a stable population. This could result in Japan’s population decreasing from 125 million to 88 million by 2065.

Why is there a declining birth rate in Japan and South Korea?

They mention various reasons for their concerns, including an unpredictable job market, high housing costs, gender and social disparities, limited opportunities for upward social mobility, and the significant financial burden of raising children in a fiercely competitive society. The statement was made on February 22, 2023.

What is Japan doing to stop population decline?

In response to a decline in population over the past few decades, the government has implemented several initiatives. These include policies to improve child care services and housing for families with children. In some rural towns, couples are even being incentivized with financial rewards to have children. This has all been launched as of January 23, 2023.

How can Japan fix its population?

Japan’s low birth rate can only be improved through two methods on the domestic supply side. Firstly, incentivize couples to have more children by providing financial support. Secondly, provide additional economic benefits like paid parental leave or subsidized childcare to support families. This is an approach that is being considered as of January 24, 2023.

What is the 2025 problem in Japan?

Japan is facing a significant issue known as the “2025 problem” caused by the rapidly increasing number of residents aged 75 years or older, with the greater Tokyo metropolitan area being the most severely impacted region. This is a major concern for the country as a whole.

Technological Advancements

Another factor that may be contributing to Japan’s population decline is technological advancements. With the rise of automation and artificial intelligence, many jobs previously done by humans are now being replaced by machines. This can lead to a decrease in the number of available jobs and may discourage young people from starting families due to concerns about job security and financial stability.

Cultural Attitudes

Cultural attitudes towards family and parenthood in Japan may also be contributing to the population decline. Japanese society places a strong emphasis on individualism and self-reliance, which can make it difficult for people to prioritize family over personal goals and ambitions. Additionally, there is still a stigma attached to single parenthood in Japan, which can make it difficult for single mothers to raise children on their own.

Environmental Concerns

Environmental concerns may also be playing a role in Japan’s population decline. With climate change and natural disasters becoming increasingly frequent and severe, many young people may be hesitant to bring children into a world that seems increasingly unstable and uncertain.

Alternative Lifestyles

Finally, the rise of alternative lifestyles may also be contributing to Japan’s population decline. Many young people in Japan are choosing to pursue non-traditional lifestyles, such as cohabitation or remaining single, which may not involve having children. While these lifestyles can provide greater flexibility and freedom, they may also contribute to a decline in the overall birth rate.
