Company Profile

Greetings from the President

Since the establishment of our company in 1918, we have been mainly engaged in the trading and primary processing of precious metal materials and the manufacture and sale of industrial-use precious metal products. With your warm support, we have been able to achieve steady growth.
Precious metals have not only added vividness to our lives with their beautiful and majestic colors, but have also contributed immeasurably to the advancement of science with their various properties that cannot be found in any other material, and in this sense, the expression ""precious metals"" is indeed to the point.
As one who deals with precious metals, we have been striving to improve our technology up to the present day so that we can always provide high quality materials and products to the jewelry and accessory industry as well as to the world's most advanced fields such as electronics, automobiles, nuclear power, and medical.
As a regular member of the Japan Gold Metal Association, which was established in 1979, we are committed to contributing to the expansion and development of the gold market in Japan, so that people can buy and sell gold with peace of mind.
We believe that precious metals will continue to increase their importance in the ever-evolving industrial world, regardless of whether they are visible or invisible to us. In this environment, each and every one of our employees, from manufacturing to sales, will continue to respond to the needs of our customers with a sincere attitude, without being complacent about our history and trust since our establishment. We look forward to your continued support and encouragement.
