Kintsugi involves a specialized arsenal of urushi lacquers, fillers, and delicate application tools tailored for precision and patience. Gold powder—the heart of Kintsugi’s beauty—is crafted meticulously, available in fine keshi-fun, robust maru-fun, or intermediate nobe-fun varieties. For gold powder for Kintsugi, several specialized producers—both traditional artisan makers in Japan and high-end suppliers abroad—craft the ultra-fine metallic powders essential to achieving that signature golden finish. Japanese craftsmanship still leads in Kintsugi tools, with trusted names like Watanabe Shoten, Minowa Shikko, and Tsutsumi Asakichi offering materials.
