After Twenty Years, a Fresh Start: Why Japan’s Late-Life Divorces Keep Rising

Japan is getting married a little more and divorcing a little less. Yet one group is moving firmly in the other direction. Final vital statistics from the health ministry show that couples who had lived together for at least 20 years accounted for a record 24.2 per cent of all divorces in 2025, even as the total number of divorces fell to about 179,000. Divorces after 30 or more years together were the only category that actually grew.

The Japanese term for this is jukunen rikon, often translated as “late-life” or “silver” divorce. The share first crossed 20 per cent in 2019 and has crept up almost every year since. Behind the numbers is a quiet rewriting of what a long marriage is expected to deliver.

A hundred-year life changes the maths

Marriage counsellors in Japan often point to one simple factor: time. When retirement at 60 or 65 was followed by a relatively short old age, many unhappy couples simply waited it out. Today a healthy 60-year-old can expect several more decades of life. For someone who has spent 30 years managing a household around a partner’s career, the question changes from “how do I get through the rest?” to “what do I want to do with it?”

Retirement itself is often the trigger. A husband who was rarely home during his working years suddenly occupies the living room all day. Couples who had little shared routine discover they have even less to talk about. Some lawyers say that the arrival of a retirement lump sum is when many wives finally feel able to leave, because it is the first time a meaningful share of family assets becomes concrete and divisible.

Women are usually the ones who file

In cases that reach the courts, wives file roughly twice as often as husbands. Incompatibility is the most common reason given, but financial neglect and psychological abuse also feature prominently. Family lawyers describe older clients who spent decades in marriages where they were expected to stay home and defer, and who now want a life in which their opinions and money are their own.

Money remains the biggest obstacle. Japan’s labour data show a sharp generational split: among women aged 25 to 44, most employees now hold regular, full-time positions, but among those 45 and older, more than half are in non-regular jobs with lower pay and weaker pensions. For many older women, leaving a marriage still means a real risk of poverty. Some choose a middle path, remaining legally married while living separately, a pattern that rarely appears in official divorce figures.

Smartphones and shifting norms

Social media has also played a part. Women in their fifties and sixties now see peers travelling, studying or starting businesses, and they can find detailed information about property division, pension splitting and legal procedures in minutes. Public awareness of domestic violence between spouses has grown, too, making it easier to name experiences that previous generations were told to endure.

Men, meanwhile, often describe the experience as a shock. Many say they had no idea their partner was unhappy. Counsellors note that men of this generation frequently have few friends outside work, which makes a late divorce especially isolating and can raise health risks in old age.

What it says about Japan

It would be easy to read the trend as a sign of family breakdown. A more accurate reading may be that Japanese marriages are being held to new standards. Later generations are marrying with different expectations about shared housework and dual incomes, and the share of very early divorces has actually fallen below 30 per cent for the first time. The rise of late-life divorce may be the older generation’s version of the same shift, arriving decades late.

For policymakers, the practical questions are about safety nets: fair pension splitting, affordable housing for single older people and support for those, often women, who leave long marriages with limited savings. For everyone else, the numbers carry a gentler message. It is never too late to ask whether the life you are living is the one you want.
