From the CEO'S DESK

Kimiko Kayama

Welcome to our company’s website.


In 1985, I inherited this metal scrap business from my father, who taught me the value of sustainability and integrity. Over the years, we’ve faced many challenges, but with hard work, innovation, and a commitment to ethical practices, we’ve grown into a respected player in the industry.


As we celebrate our 90th anniversary in 2025, I’m proud of how far we’ve come. We’ve embraced new technologies, improved our sustainability efforts, and built lasting relationships with our customers and partners.


Looking ahead, we remain committed to excellence, innovation, and a sustainable future. 


Thank you for your continued support!
