PRESIDENT’S MESSAGE

KOJIMA will continue to aspire,
respond, and support.

Thank you for visiting our website.
We're much appreciated with your continued support.
Thanks to your warm support, Kojima Corporation celebrated
its 100th anniversary on March 23, 2017.
Founded in Osaka in 1917, our company has focused on its contribution to society
for 100 years based on the philosophy of the founder, supported by our business partners.

Today, the ever-changing environment surrounding the industry makes it difficult to respond to the needs of our customers by merely applying old ways of thinking.
While staying ahead of the curve with market changes, we will work on issues by taking on all kinds of challenges with the spirit of learning from traditions we have built since our founding, while gaining new insights without dwelling on tradition.

We will continue to respond to the needs of society and maintain our firm position as a general trading company for piping materials and moreover, contribute toward a prosperous society and earn more trust from our stakeholders.
Thank you for your encouragement and support.

Nobuyoshi Kitagaki,
President
