The Society for the Promotion of Japanese Sword Culture (NBSK) is a public foundation established in 2009, dedicated to preserving and promoting the rich heritage of Japanese sword culture. With roots extending back over a millennium, NBSK aims to cultivate public appreciation for the artistry and historical significance of Japanese swords, regarded as a vital symbol of national culture. The foundation engages in various activities, including hosting sword exhibitions, offering training courses for swordsmiths, and conducting research on traditional craftsmanship.

NBSK also publishes informative materials on Japanese swords and actively collaborates with other organizations to stage events and competitions that highlight the skills of contemporary sword artisans. By fostering the next generation of craftsmen and connecting enthusiasts globally, NBSK seeks to enrich minds and sustain the tradition of Japanese swords, ensuring they are recognized not only as artifacts of Japan's past but also as treasures for future generations
