Since its foundation in 1941, TAISEI KIKO has pioneered Japan’s water, sewage, and gas pipeline maintenance sector, continuously engaged on the frontier of technological innovation in product development and maintenance work.

TAISEI, in the Japanese market, has long enjoyed its reputation as a leading enabler of interruption-free construction work in pipeline replacement and maintenance and as a major manufacturer of various pipeline joints.

Our products include TAI-FLEX, a flexible expansion joint that moves freely like a human joint, and EARTHQUAKE RESISTANT REINFORCEMENT FITTING, FLANGE REINFORCEMENT FITTING, and FLANGE SUPPORT which are mounted onto existing pipe joints to prevent them from pulling out. These products make a major contribution to improving earthquake resistance and extending the service life of water pipes. They also protect water pipes from threats such as ground subsidence or earthquakes. Thanks to these products, we at TAISEI KIKO have earned an excellent reputation for our technology.

In October 2021, we carried out experiments on the behavior of underground water pipes under conditions of ground collapse. This was done using E-Defense, a large-scale experimental facility of the National Research Institute for Earth Science and Disaster Resilience. The results demonstrated the excellent performance of our earthquake-resistance products, and raised expectations for our products and technologies.

Today's society is constantly changing from moment to moment, and it is our mission at Taisei Kiko to always respond quickly to these changes, without ever standing still.

Going forward, we will strive every day to improve our technologies, and continue our assiduous efforts to develop new products and new construction methods.

In the area of overseas expansion, we at Taisei Kiko have worked for a long time to promote technical exchange with overseas partners and expand our networks with foreign firms. Our business motto, “Gratitude and Repayment to Society,” and the founder Shinkichi Yano’s last message, "Be remindful of the original enterprising spirit," are engraved into the mind of every TAISEI employee, constituting our unflinching corporate culture, even 80 years after our founding. We apply ourselves every day, never forgetting even for a moment to repay the water utility industry and contribute to society through our business. As a total coordinator of pipeline maintenance, we will continue to develop products and construction methods that truly meet customer needs.

As President of TAISEI KIKO, I look forward to your continuing guidance and support.
