About Us

In 1916, Nousaku began manufacturing Buddhist ritual objects, Japanese tea sets and vases made of brass and bronze in Takaoka, Japan. The city has flourished since 1609, and built its reputation as the center of the copper industry in Japan over those 400 years.

Casting is a manufacturing process in which a molten metal is poured into a mold to form an object of the desired shape. Every Nousaku product starts with the creation of a sand mold, and then undergoes several finishing processes. Hand-finishing by experienced craftsmen accentuates its material beauty and fineness.

Sand Casting

Place a metal frame on a wooden mold of the intended shape.
Ram sand into the frame.
Remove the wooden mold.
Pour the molten metal into the hollow cavity of the sand mold.
Take out the product from the sand mold after solidified.
Grind the surface by a lathe and then handfinish using bladed tools.
Apply coloring if necessary.
