Japanese Sand Casting: A 300-Year Heritage of Sustainable Craft

This piece is crafted by a foundry with a legacy spanning over 300 years since the Edo period. They have mastered "Sunagata-chuzo," or sand casting, a traditional Japanese technique where metal melted at 1200°C is poured into sand molds. While their exceptional craftsmanship is trusted for manufacturing cutting-edge rocket components, they also embrace a circular production model that recycles materials, showing deep consideration for the future. Each creation is infused with the enduring spirit of Japanese tradition, innovation, and sustainability.
