Komin Osawa was born in 1941, in the district of Takaoka, famous for its copper-utensil industry. In 2005, his 'chukin' work was designated as an important intangible cultural heritage.

Chukin is a goldsmith technique that encompasses metal-fusing, mold-injection and casting. The craft dates back to the Yayoi period. It includes various casting methods such as, 'sogata, 'rogata, 'sunagata' and 'yakigata'. With the yakigata method, large work such as statues could be manufactured. Yet experience and mastery of the technique are necessary in all processes of the work.

Through the yakigata method, Osawa discovered his original 'igurumi' method to achieve his own aesthetic effects. Moreover, he also experiments with the beauty of geometry.

It is common for Osawa to work until midnight, yet he asserts with a fresh smile, 'Something just comes out of my brain when I'm working really hard.'
