A Message from the Founder

What I wanted to give
the self I was that night.

Before I talk about Rainbow, let me start with the story of one night.

It was around the time I first left my child at nursery. In the classroom, children the same age ran about and traded words. My child had not yet caught up to that.

At home, we celebrated together each time yesterday's impossible became today's possible. But the moment you place a child among a group, the measuring stick changes. No one said a word to me, yet on the walk home from pick-up there was a moment I realized: "my child is different."

That night, I sat alone and turned it over and over.

How do I support this child? Search, and all you find are generalities. In the dead of night there is no one to tell this worry to. And when tomorrow comes, I have to send them off, the same as before.

—— People living through nights like this exist all across Japan, at this very moment.

Years later, I could finally put it into words. What I truly wanted that night was someone who would find what is good and keep saying it out loud for my child. Not “they’ll catch up eventually,” not “let’s wait and see a little longer,” but someone who would meet this child as they are today and hand over their good points in words, patiently, every day— I wanted someone like that beside me.

It’s the thing a parent seems most able to do, yet finds hardest. Precisely because you face them every day, it’s the “can’ts” that burn into your eyes. Thirty minutes to get dressed again today. Couldn’t play with friends again today. Amid that pile-up, the room to catch a small good moment and say “that’s wonderful” that same day has vanished by the time night falls.

So someone has to build a system that carries that role — every single day.

This isn’t a “nice to have.” It’s strange that it doesn’t already exist. That society has no system to speak daily to a child’s strengths. That a parent carrying it all alone has no window that reaches them in the dead of night. That an older person with no one to talk to when they come home from the field goes unseen unless they raise their own hand. — These can be solved, if someone builds them in earnest.

So I’m building it.

Rainbow is a project to make “finding what’s good and keeping on saying it” the standard of society, through AI and the local community. For children, and for older people. Across generations, for everyone living through the same night.


If we wait, no one will build it.
So I will.

To give what I longed to give the self I was that night —
now, to someone living through the same night.

Others are living
the same night, right here.

Parents carrying a child’s night alone. Older people with no one to talk to after coming home from the field. Children in a developmental “gray zone” who don’t even qualify for support. — No one lives “that night” alone. The same night exists all across Japan.

A voice I heard on a phone call.

They had begun repeating the same stories they’d long stopped telling. “I don’t want to be a burden,” they’d say, never speaking their real fears. “I won’t go out anymore, even if I’m invited.” — They said it quietly.

— A voice I heard on the other end of the line

After I put down the receiver, I couldn’t move for a while.

This person hadn’t had anyone find what was good in them for years. Try to visit, and they refuse — “I don’t want to be a burden.” Invite them, and they say “I won’t go.” Society stopped inviting, so they stopped responding. Or perhaps they simply grew tired of responding.

It was the same structure as the child’s night.

What was missing was this: someone to find what is good and keep saying it out loud. More than missing — the system that should carry that role simply doesn’t exist in society. Not for children, and not for older people.

—— So we build it.

Turning “finding what is good and saying it aloud”
into a system.

Pillar 01

Adult Connect

Outreach that actively reaches older people

“Unless you raise your own hand, no one finds you” — we end that. In Adult Connect, AI keeps reaching out actively by LINE and phone, and translates each person’s good points back to the community. Even those who’ve kept declining invitations receive a gentle voice — never forced, never a strain.

Pillar 02

Kids Bloom

Sharing a child’s good points, every day

“They’ll catch up eventually” doesn’t get you through tonight. Kids Bloom is a system that finds what is good in your child as they are now — every day — and keeps saying it out loud. Its voice reaches children who have no diagnosis but leave you “a little worried,” and becomes a support so that no parent has to carry the night alone.

The two pillars are not separate services.
They are one system, built to reach across generations into the same “night.”

How the business works.

This is how Rainbow runs.
Good intentions alone won’t reach anyone’s night.
We’ve properly designed the system that delivers.

01 / PROJECT MAP

The whole picture

The voices of older people, children, and families — AI gathers them and delivers them to municipalities, facilities, and families. Two entry points, Adult Connect and Kids Bloom; a core powered by AI dialogue; and a dashboard that reaches the municipality. We’ve put the whole intergenerational system into a single diagram.

02 / SOLUTION

AI–older adult conversation screen

No smartphone needed — a single phone call is enough to take part. reach out → measure loneliness → reconnect — AI repeats these three steps every day, so that “nights no one notices” are never repeated again.

03 / PRODUCT

Connecting through four screens

Older people, children, municipalities, operations. Rainbow runs on four screens, each tailored to its user: Adult Connect / Kids Bloom / Municipal portal / Operations portal — every one of them designed from the voices of the field.

Why start in Shiroi?

Shiroi is a land of pears.
You grow, you wait, you harvest, and return it to the soil.

In this town, a culture of waiting and the wisdom of nurturing run deep.
And I myself live here.
I’ve raised my child and cared for family here.

Not a business dreamed up on paper, but a system that grows out of my own life
that’s how Rainbow begins, from Shiroi.

Start where I live. Reach where it's needed.

A project that doesn’t “replace” existing services
but “fills the gaps” between them.

Shiroi already has excellent initiatives, such as the Shiroi Elderly Watch Network and the Children’s Development Center. Rainbow was born to fill the “gaps” between them — three blanks in particular: active outreach by AI, a structure that connects generations, and outcome reporting based on KPIs.

PROJECT FOUNDER

Founder of the Rainbow Project. As someone living in Shiroi, I want to grow a new form of support — built by AI and the local community — around one principle: never leave alone the people who fall through the gaps of the system. From that wish, I started this project on my own. Grounded in hands-on experience in welfare and community support, I aim for work that reaches the field, not theory on paper.
