What is the "SustainaBook Project"?

The "SustainaBook Project" (hereinafter, "this Project") is a social contribution activity that began in 2023 with the aim of creating reading opportunities for children and resolving reading disparities in local communities.

This Project is implemented in cooperation with BOOKOFF stores nationwide and local children's facilities as an initiative that reduces environmental impact by extending the lifespan of unneeded items and allows anyone to participate in social contribution activities easily and without burden.

During the period, based on the number of books sold by customers at participating stores, a donation amount will be calculated at a rate of 1 yen per 10 items. Reuse books equivalent to the calculated amount will be donated to children's facilities in need of books.
