A Japanese cast-iron foundry established at the end of the Edo period in 1852, currently run by the fifth generation of Genjuro Oikawa. Located in Oshu, Iwate, it has been producing a wide catalogue of cookware and homeware for over 170 years, preserving the traditional craft of Nambu Tekki. OIGEN’s incense holders reveal the history of each use through their bare, uncoated iron, a promise to stay true to the material.
