Company information
Our company has been a primary wholesaler specializing in unique non-ferrous metals, such as [phosphor bronze bars, nickel silver bars, and beryllium copper bars], since our founding in 1964. Since our establishment, we have always worked with a spirit of gratitude and challenge under the management philosophy of "coexistence and mutual prosperity." By maintaining a sense of gratitude, our actions and responses change. As a result, we believe we can grow into a company that earns the trust of everyone and society. Moreover, challenges often come with anxiety, but as the saying goes, "it's easier to give birth than to worry," taking that first step often leads to better outcomes than expected. We aim to continue challenging ourselves with a broad perspective and knowledge. While cherishing the core values of gratitude and challenge that are the foundation of Shinwa Shoji Co., Ltd., we will work together as a company to advance in the wholesale business.
