“best pot” employs a cast iron lid and a ceramic earthenware pot made of Banko-yaki (Banko ware) which boasts a long history of over 300 years in Yokkaichi City in Mie. Produced by Nakamura Manufacturing with its high-precision technology to carve difficult-to-cut materials used in rocket and aircraft parts, the gap between the lid and the pod was minimized to 0.01mm or less. Thanks to its excellent sealing, best pot can be used both as a regular earthenware pot and a waterless cookware. In addition, its sleek design can also serve as a tableware. With the unique design that combines a double-layered structure and a shape of “hagama,” Japan’s traditional rice cooker, it allows heating up evenly and thoroughly to keep the soup temperature above 70 degrees even after two hours. It is an innovative product that fuses Japan’s traditional craft with high-precision processing technology.
