HOSONO Corporation

Founded in 1931 as Hosono Iron Works, our company began as a specialized manufacturer of pressure machine castings, with a focus on cast iron pipes for pumps. For over 90 years, we have continued to move forward, grounded in a spirit of sincere craftsmanship.
Today, we are also engaged in real estate projects that support people’s lifestyles and in businesses addressing challenges faced by local communities.
On October 1, 2025, we took a new step forward by changing our company name to "HOSONO Corporation."

Moving ahead, we will continue to contribute—through our business activities—to the success of our customers, the well-being of all our employees and their families, and the development of our communities. By walking and growing together with all our stakeholders, we aim to realize a sustainable future.

We sincerely ask for your continued warm support and patronage.
