The company began in 1956 as Sanwa Shutter Manufacturing Co., Ltd., a neighborhood factory with the mission of “contributing to society by providing safety, security, and convenience.” Guided by this mission, we have worked alongside our customers for the past 70 years to become the region’s number one building material manufacturer.

During this time, society has changed greatly. However, thanks to the efforts of our predecessors and the support of our many stakeholders, we have grown through our shutter, door, facade, partition, and other entrance products to become a company trusted by customers nationwide.

As we mark this 70-year juncture, we will reflect on our progress thus far and continue to take on new challenges for the next era. We are committed to remaining a meaningful presence in society as a company that supports people’s daily lives, and each of our employees strives wholeheartedly to achieve this.

We look forward to your continued support and patronage.
