Japan’s Ageing Population, Seen from the Train Window

Ride a local train for an hour outside any Japanese city and you will pass a closed primary school, a shuttered shopping street, an unstaffed station, and fields being worked by someone well past seventy.

Japan has the oldest population of any large country, and it is the first to work through what that means at scale. It is not hidden and it is not only a rural story. For a visitor prepared to notice it, it explains more about contemporary Japan than any temple.

What you actually see

Unstaffed stations. A rural station with an intercom instead of a ticket office, a single ticket machine, and a box you drop your fare into. Some have no barrier at all.

Closed schools. Small primary schools have been merged and closed in large numbers as birth cohorts shrank. Many are visible from the train: a 1970s concrete building with a running track, an empty playground, and sometimes a sign showing it has been converted into a community centre, a café, a hotel or a fish farm.

Shutter streets. Shutter-dori — a covered shopping arcade where most units have their shutters permanently down. Almost every regional city has one, hollowed out by out-of-town retail and by shopkeepers with no successor.

Older workers, everywhere. Taxi drivers, parking attendants, construction flaggers, security guards, station staff, farm workers. Many are on post-retirement re-employment contracts at reduced pay.

Akiya. Empty houses, roughly nine million of them, often inherited by children who live in a city and cannot easily sell, demolish or rent. A tax structure that penalises empty land more than an empty building has historically encouraged owners to simply leave them standing.

Rice paddies inside cities, worked by an elderly owner, taxed at agricultural rates, and pending a decision that will probably be made by the next generation.

The numbers, briefly

Japan’s population peaked around 2008 and has been declining since. Around 29% of people are 65 or older — the highest proportion of any large country — and the projection is for that to keep rising past a third.

Births have fallen below 800,000 a year, well ahead of official projections. The total fertility rate has been below replacement since the 1970s.

The consequences compound: fewer workers supporting more pensioners, shrinking domestic demand, and a rural population falling faster than the national average as young people move to the cities and do not return.

Why it happened

No single cause, and the standard explanations all carry weight.

Cost and precarity. Raising a child in urban Japan is expensive, and the growth of non-regular employment left a generation of young adults without the income security that marriage and children have traditionally been organised around.

Work and gender. Long hours and a workplace culture built around an employee with a full-time homemaker at home made combining career and family genuinely difficult, particularly for women. Childcare shortages persisted for decades.

Marriage. Births outside marriage remain rare in Japan — around 2%, against 40–60% in much of Europe — so falling marriage rates translate almost directly into falling births.

Housing and geography. Concentration in Tokyo, where space is expensive and commutes are long.

Government responses — childcare expansion, parental leave reform, subsidies — have not reversed the trend, and this is now a central political question rather than a technical one.

What Japan is doing about it

Visible to a traveller in several ways.

Automation. Ticket machines, self-checkout, ordering tablets in restaurants, robot servers in family restaurants, and automated hotel check-in. Japan automates customer-facing labour partly because it is short of people to do it.

Foreign workers. The number of foreign workers has risen sharply, and it is most visible in convenience stores, construction, agriculture, elder care and hospitality. The specified skilled worker visa categories introduced in 2019 were a significant policy shift in a country long reluctant to frame itself as an immigration destination, and the politics remain contested.

Raising the retirement age. Companies must now secure employment opportunities up to 70, and the visible result is a workforce with a lot of people in their late sixties and seventies.

Consolidation. Schools merged, hospitals concentrated, bus routes cut, and rural rail lines closed — JR Hokkaido and JR West have both withdrawn from unprofitable lines.

Compact city policy. Toyama is the best-known example, deliberately concentrating population and services along a rebuilt light rail spine rather than trying to service a spread-out city with a shrinking tax base.

The akiya question

The empty houses have become internationally famous, usually through articles about houses selling for the price of a used car.

The reality is more complicated. Many are structurally poor, built before 1981 seismic standards, in villages with no shop and an hour from a hospital. Municipal akiya banks list them, and some towns offer renovation grants to attract residents.

Foreign buyers can purchase Japanese property freely — there is no restriction on foreign ownership of land or buildings — but ownership confers no residence right, and renovation, taxes, and the practicalities of living in a depopulating village are the substance of it.

There are genuine success stories, particularly where remote work has made rural living viable, and the government’s regional revitalisation programmes actively encourage it.

What it means for a visitor

Three practical things and one that is not.

Rural transport is thinner than the map suggests. A branch line may run five trains a day and a village bus twice. Check the timetable rather than assuming.

Some places want you there. Regional tourism is one of the few growth levers a depopulating municipality has. Visiting the less-famous prefectures is not merely avoiding crowds; it puts money where it is needed.

Old buildings are being reused. Some of the best accommodation in rural Japan is now a converted school, a restored farmhouse, or a machiya townhouse saved from demolition. Kominka renovation is a real movement and the results are frequently excellent.

And the thing that is not practical: it is worth simply noticing. Japan is running an experiment that every developed country will eventually run, and it is doing it in public, in the open, from the window of a local train.

Where to see it

If this interests you as a subject rather than a backdrop:

• Any local line in Tohoku, Shikoku or the San’in coast, on a weekday afternoon.
• A regional city’s covered arcade at 3pm — the contrast between the station building and the old shopping street a few hundred metres away.
• Ojiya, Yubari or the Noto peninsula — places that have made depopulation part of their own public story.
• A converted school — dozens now operate as hotels, cafés, breweries and museums, and they are usually happy to explain what happened.

Questions people actually ask

Is Japan's population really shrinking?

Yes, since around 2008, by several hundred thousand a year and accelerating. Around 29% of people are 65 or older, the highest share of any large country.

Can I buy one of the cheap empty houses?

Legally yes — there is no restriction on foreign ownership. In practice, most are old, seismically substandard, remote, and need substantial work. Ownership grants no residence rights.

Why does Japan not simply allow more immigration?

It has been increasing foreign worker numbers substantially since 2019 through specified skilled worker visas, but a permanent-settlement immigration policy remains politically contested and the framing is still largely about temporary labour.

Does it affect travel?

Yes, in rural areas: reduced train and bus services, closed line sections, unstaffed stations, and fewer restaurants open in the evening. Plan rural days around the timetable.

Are rural areas dying?

Many are depopulating steeply. Some are being deliberately reinvented — art projects, remote-work incentives, tourism, kominka renovation. The Setouchi art islands are the best-known example of that working.

Is it rude to ask people about this?

No. It is discussed constantly in Japanese media and people are generally direct about it. Approach it as a serious question rather than a curiosity and you will get a serious answer.
