The average life in Japan

What does an average life in Japan look like? From birth weight to school, first job, marriage, children, peak pay, retirement age and life expectancy, this page lines up the latest official figures from Japan's ministries in age order, for men and women. At the end, it asks why almost nobody actually lives the average life.

Birth: about 3 kg

According to the Ministry of Health, Labour and Welfare's Vital Statistics (2025, final figures), the average birth weight was 3.04 kg for boys and 2.95 kg for girls. Japan recorded 671,270 births in 2025, the fewest since the survey began in 1899.

School: almost everyone finishes high school, about 6 in 10 go to university

The education ministry's School Basic Survey (2025) shows 98.6% of junior high graduates go on to high school. The share going on to an undergraduate university program (including those who enter after a gap year) is 58.6%: 60.7% of men and 56.5% of women. Including junior colleges, it is 61.5% for men and 61.2% for women, almost no gap. So the "average person" goes to university, but about 4 in 10 people born in the same year take another path.

Work: about ¥260,000 to start, peak pay in the late 50s

Of those who finished university in March 2025, 77.0% went into a job (School Basic Survey). In the 2025 Basic Survey on Wage Structure, new university graduates earned ¥264,900 a month (men) and ¥259,700 (women).

In the same survey, monthly pay for regular workers rises with age and peaks at ¥445,600 for men aged 55–59, and at ¥305,700 for women aged 45–49 and 55–59, before falling in the 60s. Men's pay climbs to about 1.8 times what it is in the early 20s; women's rises more gently, to about 1.3 times.

Marriage and children: first marriage around 30

Vital Statistics (2025, preliminary annual figures) put the average age at first marriage at 31.0 for husbands and 29.7 for wives, and the mother's average age at the birth of her first child at 31.0. These averages only count people who married or had a child; many people do neither.

Home: about 6 in 10 homes are owner-occupied, 8 in 10 for older households

The Statistics Bureau's Housing and Land Survey (2023) found that 60.9% of homes are owner-occupied. Among households with someone aged 65 or older, 81.6% live in a home they own. Many people rent when young and own later in life.

Retirement: 60 is common, moving toward 65

The 2025 report on the employment of older workers (as of June 1, 2025, firms with 21 or more employees) shows 62.2% of firms set the mandatory retirement age at 60 and 27.2% at 65. Firms with a retirement age of 65 or older, including those with none, rose 2.3 points to 34.9%. 99.9% of firms have some arrangement, such as a higher retirement age or continued employment, that lets people work until 65.

Old age and death: life expectancy 81.35 for men, 87.33 for women

According to the 2025 Abridged Life Tables, life expectancy at birth is 81.35 years for men and 87.33 for women. At 65, men can expect to live another 19.68 years and women another 24.52. 26.7% of men and 50.8% of women live to 90: one woman in two reaches 90.

Healthy life expectancy, the years lived without health problems limiting daily life, was 72.57 for men and 75.45 for women in 2022. That is 8.49 and 11.63 years short of life expectancy in the same year.

The median lifespan, the age by which half of those born have died, is 84.13 for men and 90.17 for women, nearly three years above life expectancy. Deaths at younger ages pull the average below the middle.

Almost nobody lives the average life

Very few people match every line of that table. About 6 in 10 go to university; the average lifespan is shorter than the median; the ages at first marriage and first birth only count those who married or had children. Each number is a common value, but a life where all of them line up is rare.

And the year, the prefecture and the household you are born into shift every one of these numbers. See Where and into what family you are born, Work and wages and How long you live.

Live one life, not the average

Born in Japan is a Japanese life simulator that uses public statistics like these to let you live one person's life, born somewhere in Japan, one year at a time. You choose your schooling, work, marriage, home and spending at each turning point, and the statistics and the game's assumptions turn that into a life unlike anyone else's. At the end, you see where your life landed among people with the same birth.
