We do not leave them alone when they are hurting.
We aim for a society where, even in loneliness or isolation, there is somewhere to turn.
Some struggles are hard to solve. Some cannot be fixed by logic alone. Some feelings have nowhere to go.We stay with young people until ”there’s nothing I can do” can begin to feel like ”I’ll be okay.”help them find their own answers, look for another path, and choose to keep living.
Caught in the gaps of social systems, facing family issues, school problems, and mental illness. The problems vary in type and severity, but many share the same feeling: ”there’s nothing I can do.”

Child suicide is on the rise. 2024 saw a record high of 529 cases.
Abuse often continues across generations and the cycle persists.
School non-attendance is increasing. 2024 saw a record 350,000 cases.
The 1st family is “the person's own family,” the 2nd is “the local community.”The 3rd family is a network of people you may not know personally, but who can still be there for you.Ultimately, finding a place of belonging within reach.
For teenagers who are not connected to existing support systems,
we build networks of mutual support among peers — not top-down adult intervention.
We try everything little by little until they feel they can trust us.
Teenagers' problems are complex and often hard to solve.
When fundamental resolution is difficult, first help them get through.
We aim for a future where they can live joyfully as adults, breaking the cycle of problems.
First, finding a sense of “okay” even in hard situations —finding their own answers, looking for another path, choosing to keep living.Then, finding a place of belonging within their own reach.

Representative
The catalyst for her work was losing her younger brother to suicide during her second year of university. For a year she was unable to do anything, but drawing on her love of making things, she tried building a message board for people struggling with their home environment — and far more people gathered than she expected. While receiving heartfelt messages of thanks, she also realized the gravity of the issues people were facing, and felt she had to do more. She left her first job at LINE Corporation and founded NPO The Third Family (Daisan no kazoku). Today she is not driven by her own past, but is fully absorbed in creating better circumstances alongside the teenagers who fall through the cracks.
