Japanese tetsubin (iron teapots) evolved from larger vessels used centuries ago to heat water for tea and provide warmth and humidity in the home during the winter. Without many specialized machines, artisans centuries ago had to do nearly everything, from preparing the molten iron to perfecting the last design detail, by hand. Today, craftsmen at Iwachu pay respect to this tradition by infusing each product with skilled precision and detail throughout the entire manufacturing process. This pot has a hobnail design. The hobnail design is one of the oldest and most classic tetsubin designs, favored by many for its simple beauty. Iwachu is one of the finest and most respected manufacturers of Japanese ironware, with a company history of over 100 years. The superior quality, beauty and lasting durability of Iwachu products have earned them the worldwide reputation as the leading manufacturer of authentic Japanese tetsubin.
