Company information
Saito Iron Works celebrated its 77th anniversary in May 2025. We would like to express our heartfelt gratitude to our customers, business partners, and all employees who have supported us thus far. In addition to the flood control projects we have been engaged in, we have recently been focusing on disaster prevention gates to address issues such as increased water levels due to sudden heavy rains and tsunamis, steadily building our track record. Aiming to become a 100-year company, we will take on various challenges in the next 25 years, in addition to our sluice gate business. I am confident that this will lead to the growth of our employees, including myself, and contribute to the stability and prosperity of the company. We will continue to strive towards realizing a society in harmony with water, people, and nature, both now and in the future.
