“Tsushima Ocean Knife” series is an innovative masterpiece that merges environmental consciousness with traditional craftsmanship, born from a project dedicated to preserving the beautiful seas of Tsushima. Developed in collaboration with the General Incorporated Association Tsushima CAPPA and Tsushima City, Nagasaki Prefecture, the Japanese knife brand “MUSASHI JAPAN” completed this product after two years of development. Sales began in June 2024, offering a total of 45 variations with five types of blades and nine handle colors. This series utilizes a unique recycling process to transform marine plastic waste that washes up on Tsushima’s shores into colorful and lightweight handles. Through collection, sorting, and cleaning, the waste is reborn into handles that combine both beauty and functionality. Additionally, the series overcomes the challenge of molding mixed marine plastic materials, which were traditionally difficult to process, by leveraging thick-wall molding technology. This achievement contributes to reducing environmental impact and promoting a sustainable society. The blades, crafted by skilled artisans using traditional techniques, feature exceptional sharpness and elegance. Moreover, each handle is embedded with an NFC chip, enabling users to conveniently access detailed product information and environmental conservation efforts via their smartphones. Since its launch, the product has gained significant support, selling over 200 units per month. Furthermore, 95% of “Tsushima Ocean Knife” customers are foreign nationals, reflecting high recognition of Japanese craftsmanship and sustainability initiatives from international audiences.
