Work in your seventies is already normal in Japan. It just doesn't look the way foreign HQs picture it. Japan now has 107,677 people aged 100 or older, the first count above 100,000. If you run a team here, the number that matters more is 36.2%, the share of people aged 70 to 74 who were working in 2025.

The centenarian headline invites a leap. People live longer, so they will work longer. Part of that is already true. Another part runs into a quieter statistic, healthy life expectancy, which for Japanese men sits just past 72.

## What sits behind the 100,000 milestone

The figure counts people aged 100 and over on Japan's resident register as of September 1, 2026. The Ministry of Health, Labour and Welfare (MHLW) published it on September 15. The total rose by 7,914 from 99,763 a year earlier, and 87.6% are women.

That is under 0.1% of the population. It tells you the tail of the age distribution is getting longer. It says nothing about how many 72-year-olds can handle a full working week.

## How many people in their seventies work in Japan?

Quite a lot, already. The Statistics Bureau of the Ministry of Internal Affairs and Communications (MIC) reported in September 2026 that the 2025 employment rate was 54.5% for ages 65 to 69, 36.2% for 70 to 74, and 12.6% for 75 and over. All three are record highs. Workers aged 65 and over numbered 9.43 million, or 13.8% of everyone employed in Japan. Roughly one worker in seven.

Now look at the denominator, and at what kind of work this is. The employment rate here counts anyone who worked, including the self-employed and family members working on farms. In agriculture and forestry, 50.6% of workers are 65 or older. Among employees aged 65 and over (excluding executives), 76.1% are non-regular, and part-time work alone accounts for 52.7%.

So when you read that a third of people in their early seventies work, don't picture a third of them still in a corporate job. Most are part-time, on fixed-term contracts, or working for themselves.

Men’s average healthy life expectancy ends just past the age-70 line employers are asked to reach

One age axis from 60: employment rates (2025, Statistics Bureau), healthy and total life expectancy (2022, MHLW), and the two lines in the Act on Stabilization of Employment of Elderly Persons

1. 65Employment must be secured54.5% of people aged 65 to 69 work
2. 70Effort obligation to secure work (since 2021)36.2% of people aged 70 to 74 work. 34.8% of companies have a measure in place
3. 72.57Men’s healthy life expectancyOn average, health starts limiting daily life from here
4. 75.45Women’s healthy life expectancy12.6% of people 75 and over work
5. 81.05 / 87.09Life expectancy, men / womenAbout 8.5 years past healthy life expectancy for men, 11.6 for women

The early 70s are when people of the same age split apart. A post-65 contract built as “the same job, a bit shorter” won’t hold.

Figure 1. In 2025, 54.5% of Japanese aged 65 to 69, 36.2% aged 70 to 74 and 12.6% aged 75 and over were working, and men’s healthy life expectancy of 72.57 falls just past the age-70 line, so the early 70s are when people of the same age split between those who can keep working and those who can’t.

## Why can't you read healthy life expectancy at face value?

Healthy life expectancy is the period lived without health problems limiting daily life. Japan's 2022 figures are 72.57 years for men and 75.45 for women, as reported in the Cabinet Office's 2026 Annual Report on the Ageing Society. Against life expectancy that year, the gap is about 8.5 years for men and 11.6 for women. The latest MHLW life table, for 2025, puts life expectancy at 81.35 for men and 87.33 for women.

Two cautions. Both figures are averages from birth. A man who has already reached 65 in good health has, on average, 19.68 more years (2025 life table), so the at-birth number undersells his runway. And healthy life expectancy comes from a household survey where people report whether health affects their daily life. It is self-reported. It doesn't measure whether someone can work.

Still, the chart makes one thing hard to ignore. The early seventies are where people of the same age split widely. Some are fit and sharp. Others are managing treatment or caring for a spouse. Any plan that treats "employees aged 70" as one group will break.

## What do Japanese employers already have to offer?

The Act on Stabilization of Employment of Elderly Persons requires employers to secure jobs up to 65. Since April 2021 it has also asked them to make efforts to secure work up to 70. That second part is an effort obligation, with no penalty. It applies to the Japanese entities of foreign companies too.

MHLW's 2025 survey of 237,739 companies with 21 or more employees (as of June 1, 2025) found 34.8% had a measure in place for work up to 70. Most of it is continued employment (28.3%). Abolishing mandatory retirement accounts for 3.9%, raising the retirement age to 70 or above 2.5%, and the contract or social-contribution routes the law added just 0.1%. Meanwhile 62.2% of companies still set retirement at 60.

In practice, most of that 34.8% just stretches the post-60 rehire contract further. I covered how that contract tends to cut pay while the job stays the same in [what happens when you are rehired at 60](https://nobusato.jp/en/blog/rehired-after-retirement-age?hsLang=en). Stretch it to 70 and you add health variance on top of the pay problem.

## What I would design for a Japan entity

A young foreign subsidiary can easily file this under problems for big Japanese firms. It can reach you within a few years, though. The people you hire to bring senior client relationships in Japan are often in their fifties already.

I think work after 65 needs its own contract design. Days and hours the person can choose and adjust. A role restated in plain words at every annual renewal, saying which responsibilities stay and which go. Handover to a successor treated as a real deliverable with a deadline. And a way to scale the role down when health changes, written in advance, so nobody has to negotiate it at an awkward moment.

If you are in your fifties, ask which parts of your work will still have a price outside your company at 70. Titles rarely survive. Client relationships, teachable skills and judgment people trust usually do. Japan's long average tenure ([Japan's employee tenure numbers](https://nobusato.jp/en/blog/japan-employee-tenure?hsLang=en)) makes it easy to mistake internal standing for market value.

One thing the data can't tell me is why the 36.2% work. The Labour Force Survey asks whether people work. It doesn't ask whether they want to, or have to because the pension falls short. I suspect it's a mix. And the mix matters, because people who choose to work and people who must work need very different jobs from you.
