Nambu Iron Paperweights

In 1975, Nambu Ironware was designated as the first traditional craft by the Japanese government. From a early stage Cohana had a strong desire to create a paperweight using Nambu Ironware.

The OISEI Foundry created a stackable paperweight, adjusting the hole diameter so that it could be used as a pen stand, and using tasteful colours. 

The OISEI Founfry is located in Haneda-cho, Mizusawa-ku, a “foundry town” with many other foundry-related companies in the area. Casting has been actively carried out in this area since ancient times. The company was started in 196 and the current Chairman is the sixth family member to be the boss!

History of Nambu Ironware

Originally, the casting industry in Mizusawa began in the late Heian period (794-1185) when the Fujiwara clan invited casting craftsmen from Omi Province to polish the skills of the local people.

Production began with special-purpose items such as bells and statues of Buddha for temples, and gradually expanded to household items such as baths, pots, and iron kettles. In the old days, it took more time and effort to make things than it does now, and things were used with great care by people. Iron is recyclable, so when it breaks, it can be melted down and reused to create something new, and it was valued as a wonderful material.

However, there was a time when Nambu ironware was not so favoured.

War Time

It was 1938, the military demand for Nambu ironware became so strong that iron kettles, pots, and other daily necessities had to be discontinued. Since the material was recyclable, even temple bells were collected, melted down, and turned into guns and airplane parts. Production of non military ironware began in 1947.

The Foundry Today

The foundry today is maintaining the traditional manufacturing methods that have been handed down by the craftsmen and their predecessors, and making the most of the unique texture of Nambu ironware.
