MESSAGE Message from the President
On January 1, 2026, KORITSU INDUSTRIES CO., LTD. celebrated its 70th anniversary. We believe our long-standing success over these seven decades stems directly from our commitment to being a company that society truly values and needs.
At just 14 years old, our founder, Yasunobu Fukuhiro, enlisted as a naval aviation trainee. Having survived the devastating war, he dedicated his life to the reconstruction of Japan. He initially focused on inspiring the younger generation through education, teaching at a technical high school where he nurtured his students with a strong sense of virtue, preparing them to become the builders of a new Japan.
Driven by a passion to revitalize Japanese technology, he later chose to transition from education to entrepreneurship, founding KORITSU INDUSTRIES CO., LTD. This vision became the cornerstone of our company.
“We aspire to be a company held in high esteem by the community, advancing traditional Japanese craftsmanship while remaining dedicated to social contribution.”
In today’s rapidly evolving world, we will continue to strive to deliver essential, high-value products to society. We remain dedicated to perfecting the sand-making technology we have developed over the decades, always staying true to our founding philosophy of “RITA SOKU JIRI”—the belief that in helping others, we find our own true success.
