Kokoro Graph is a tool that visualizes the emotional memory embedded in your relationships.
It’s not a social app. It’s a record, and a research platform, for understanding who you are through the people who have shaped you.

Kokoro Research is built on a bold mission: to record the human inner world.
As a core product, Kokoro Graph reimagines human nature through the lens of relationships—mapping the emotional, psychological, and existential impact of connection.

Who changed the way you see the world?
What moments of loss made you grow?
Which relationships defined who you are?

We believe that by capturing these invisible threads, we can build the world’s first emotional infrastructure of humanity.

Kokoro Graph isn’t just for you.
It’s for the future of human understanding.
