KOYAMA SANGYO CO LTD

KOYAMA SANGYO CO LTD has been in business since 1960, which is much longer than most modern suppliers and suggests deep industry experience. The company offers used clothes, mens undergarments, and socks — a niche market that often sees lower margins but steady demand from resale and budget retailers. Unlike many new suppliers who lack verification, KOYAMA SANGYO CO LTD has no verified work email, phone number, or business documents, which raises concerns about legitimacy and ability to respond to urgent buyer needs. This lack of verification is common among older Japanese companies that may use traditional communication methods or operate through intermediaries. Buyers should request additional proof, such as a company registration or bank statement, before placing any large orders. While the long history is a strength, the missing verification signals a higher risk for new buyers who need reliable contact and documentation.
