Professional in School Project (PinS Project) launched in April 2018 at Tomioka Town Elementary and Junior High School, which reopened seven years after the Great East Japan Earthquake and Fukushima Daiichi nuclear disaster. Professionals from creative fields—artists, architects, musicians, craftspeople—join the school as "transfer students," using the school building as their workplace while sharing daily school life with children in an artist-in-residence format.

The project's philosophy, called the "PinS Model," centers on "education without teaching—an environment where serendipity thrives." By intentionally not over-instructing, adults create space for children to actively discover their innate observation, insight, creativity, and imagination. Everyone involved becomes a facilitator of learning in this intergenerational educational approach.

Another distinctive feature is that transfer students create artworks to remain at the school each year. The creative process itself becomes a learning environment, while the works serve as archives of memory—preserving the experiences and time shared at the school. By engaging people who think outside conventional frameworks, the project aims to envision a future for Tomioka that honors the town's unique character.
