Skyscrapers, a massive terminal station, neon lights, young people, and tourists from around the world.

That is the image of Shinjuku many people overseas may carry.

But within that same Shinjuku, there is a place that may offer a glimpse of another Japanese future.

Toyama Heights.

The history of Toyama Heights goes back to the early postwar years.

Built against the backdrop of severe housing shortages, the public housing at Toyama was among the pioneers of large-scale public housing developments in postwar Japan.

As the economy grew and the urban population expanded, the complex was rebuilt into the high- and mid-rise housing estate it is today — one of the symbols of the new urban lifestyle Japan envisioned at the time.

More than 70 years later, Toyama Heights now faces a very different set of realities:

  • An aging population

  • People living alone

  • Social isolation

  • A shortage of caregiving workers

  • A shortage of people able to sustain community activities

  • Housing units and spaces whose potential use is worth reconsidering

New social challenges and local resources now exist side by side.

That is why I do not think Toyama Heights should simply be seen as “an aging housing complex.”

Toyama Heights was once Japan’s future.

And now, it may once again be living slightly ahead of Japan’s future.

The Systems Exist. But on the Ground, They Do Not Connect.

I spoke with Satoshi Yoshine of Go happy! project, who has been involved in community activities centered on Toyama Heights.

For many years, Yoshine has worked in home-visit caregiving, facing issues that do not fit neatly into any single system: older people with dementia living alone, elderly couples caring for one another, and people experiencing financial hardship.

What struck me most was that the problem was not simply “a lack of support systems.”

The Tokyo Metropolitan Government has programs.

Shinjuku Ward has programs.

Care systems exist.

Community activities exist.

Volunteer frameworks exist.

The problem, Yoshine explained, is that these systems are often divided vertically into separate structures, making it difficult for people on the ground to gather the information they need and connect it horizontally to the people who need support.

  • Finding the right system

  • Assessing a person’s situation

  • Confirming which support is actually available

  • Coordinating professionals and volunteers

  • Following up after support has been provided

A single person’s life is one continuous whole.

Yet the systems designed to support that life are scattered across multiple structures.

From this, one question emerges:

The problem may not be a lack of support.
It may be a lack of connection.

The systems, people, and information already exist.

They simply may not connect at the moment they are needed most.

Can a Super-Aged Society Keep Running on Unpaid Goodwill Alone?

Another theme Yoshine returned to repeatedly was volunteering.

In Japan, there is still a strong assumption that “volunteering means doing something for free.”

The voluntary desire to help others is, of course, at the heart of what volunteering means.

But in a society where the population is aging and the need for community support continues to grow, can that work continue to depend indefinitely on individual goodwill alone?

Yoshine has a formative experience behind this question.

In the 1980s, while involved in NPO activities in New York, he was struck by the fact that people were being paid for their work while still describing themselves as volunteers.

That was where he encountered the concept of the paid volunteer.

This experience raises an important question for Japan today.

It is not simply about whether volunteering should be paid or unpaid.

It is about how society chooses to value the time, experience, responsibility, and contribution of the people who support their communities.

Yoshine told me:

“I want people to be able to say, with pride, that they volunteer.”

Supporting a community should not be framed merely as goodwill offered in someone’s spare time.

It should also be recognized as valuable activity that helps sustain society itself.

In a super-aged society, that shift in thinking may matter more than ever.

From Volunteers to the Next Generation of Community Caregivers

Still, willingness alone cannot overcome every barrier.

Some forms of support require qualifications, because caregiving and daily-life assistance include areas that demand specialized knowledge and formal training.

What Yoshine has in mind is not simply increasing the number of volunteers.

It is developing the people who are already active in the community.

For example, building a pathway such as:

Volunteer → Experience → Learning → Formal Training / Qualification → Care Work

A person may begin by talking with neighbors or helping with local activities.

They gain experience.

They learn.

They complete the training they need.

They move toward formal qualification.

And those who wish to can then step into paid, professional roles supporting their community.

This is a story about volunteering, but it is also a workforce strategy.

It is about cultivating the next generation of caregivers from within the community itself.

The answer to a labor shortage does not have to come only from bringing in new people from outside.

Finding the potential already present in local residents, developing that potential, and connecting it to new roles can also create a form of circulation within the community workforce.

Is a “Vacancy” Really Only a Problem?

Toyama Heights contains another resource worth reconsidering:

housing units and spaces whose potential use could be explored.

Vacant or underused spaces are usually framed simply as problems.

But seen differently, they can also be understood as local resources that have not yet been given a new role.

For example:

  • A place for community consultations

  • A training space for volunteers

  • A learning hub for developing caregiving staff

  • A site for digital support for older residents

  • A shared space where residents can meet one another

  • A base for community activities

Unused space can become social infrastructure.

Could space that is currently underused be transformed once again into social infrastructure that supports the community?

There are more older residents.

There are fewer people available to support them.

And at the same time, there may be spaces whose potential use is worth reconsidering.

Rather than treating these as separate problems, could they be reconnected as resources that already exist within a single community?

So What Should AI Actually Do?

This is where AI enters the picture.

But what I have in mind is not AI providing care to older people.

Yoshine himself has long wondered whether AI could help reduce the burden on the ground — by sharing case examples, for instance, or by supporting the matching of people who need help with people who may be able to provide it.

From our conversation, the areas where AI could genuinely help became more concrete:

  • Organizing information about systems and local resources

  • Organizing the circumstances of the person in question

  • Searching for available support options

  • Organizing volunteer shifts

  • Suggesting potential matches between people who can help and people who need support

  • Organizing records of past support

  • Flagging necessary follow-up

These are tasks that currently consume a great deal of human time.

If AI can take on part of that work, people can spend more of their time on what only humans can do:

Listening.

Seeing someone face to face.

Noticing small changes.

Confirming what a person actually wants.

Thinking things through together.

And building trust.

AI does not provide care.
AI can return time to care.

Which Is Exactly Why Human Judgment Cannot Be Handed Over to AI

Even as AI creates more opportunities for efficiency, not everything should be entrusted to it.

Who should be prioritized for support?

Who should be connected with whom?

How far should intervention go?

Does the person actually want the support being offered?

Leaving decisions like these to a simple score or algorithm carries real risk.

AI Human
Observe Choose
Organize Approve
Suggest Connect
Trace

The more AI’s role expands, the more clearly we need to define where AI’s responsibility ends and human judgment begins.

This is not only a question of technical performance.

It is a question of who decides, and who bears responsibility.

If AI is going to be used in a super-aged society, that structure has to be designed alongside the technology itself.

From One-Directional Support to Circulation

Seen this way, the challenge facing Toyama Heights is not only:

How do we support older people?

Information can circulate.

Support can circulate.

People can grow.

Experience and knowledge can pass from one person to another.

Underused space can take on a new role.

Community contributions can be recognized.

And people who have received support can, in turn, participate in the community with whatever they are able to give.

Receive. Connect. Give. Circulate.

Someone helped by another person today may become someone else’s conversation partner tomorrow.

Someone who cannot provide physical support may still be able to pass on the neighborhood’s history.

Someone may be good at gardening.

Someone may speak a foreign language.

Someone may be able to share their experience with a younger generation.

A person should not be seen only through the single category of “someone who needs support.”

Their experience, ability, time, and potential matter too.

Turning support that once flowed in one direction into something that circulates through the community may open a new possibility for an aging society.

Can a Place That Was Once “the Future” Build the Future Again?

There is something deeply symbolic in the history of Toyama Heights.

In the postwar years, Japan did not have enough housing.

One answer to that shortage was a new form of large-scale public housing.

Today, Japan faces a different kind of shortage.

Not enough people to provide support.

Not enough connection between people.

Not enough capacity to link separate systems horizontally.

Not enough structure to sustain community activity.

But at the same time, many of the necessary resources already exist.

The systems already exist.

The people already exist.

The experience already exists.

Community activity already exists.

The spaces already exist.

And new technology exists too.

What may be needed, then, is not to rebuild everything from zero.

It may be to reconnect what already exists.

The Community Loop Project — A Pilot Beginning at Toyama Heights

Out of this thinking, a concept is now under consideration, centered on Go happy! project:

Community Loop Project — Toyama Heights Pilot

The goal is not to introduce AI for its own sake.

It is to ensure that information, people, support, learning, space, and contribution to the community do not each end in a single direction, but instead reconnect and circulate within the community.

This is still a concept under consideration, and there are no answers yet.

Questions remain:

  • Will it actually work on the ground?

  • Where should the roles of AI and humans be divided?

  • How can volunteer activity become sustainable?

  • How can workforce development lead to real employment?

  • How can available housing units and spaces become community resources?

  • How can existing systems be connected horizontally?

There is much that still needs to be tested.

That is exactly why Toyama Heights matters.

From Toyama Heights, to Japan — and to the World

Aging is not a problem unique to Japan.

In many countries, the number of older people is growing, while challenges such as caregiver shortages, social isolation, and the difficulty of sustaining community life continue to intensify.

Of course, caregiving systems, housing systems, and volunteer cultures differ from country to country.

A framework developed at Toyama Heights cannot simply be copied abroad as it is.

But the underlying ideas may travel across borders:

  • Connecting resources that already exist in a community

  • Developing the next generation of caregivers from within the community itself

  • Turning underused space into a social resource

  • Using AI to support human judgment and relationship-building, not replace it

  • Turning one-directional support into circulation

If this model can be demonstrated at Toyama Heights, it would not simply be the success story of one housing complex.

It could become one proposal from Japan for how an aging society might respond.

So the question worth asking in the age of AI is not:

Can AI replace human care?

It is:

Can AI help rebuild the conditions in which people can care for one another?

I believe that is where AI’s real role in a super-aged society may lie.

Toyama Heights was once Japan’s future.
Could it now become a place that generates a new answer for a super-aged society?

As the CSNN Japan Desk, I will continue to follow this question — and the evolution of the Community Loop Project.
