Sin-rin is a community builder emerged from a redefined CSR approach, aiming to build forest-connected communities. With 70% of Japan's land covered by forests, many neglected, "cutting" is more important than "planting." The redefined CSR captures frontline forest workers' experiences, relays them to the public to reflect on their relationship with forests. Activities include WEB/SNS, printed ZINE, and formative experience programs, fostering a fresh perspective on human-forest relationships.
