Okinawa Builders Turn to 3D Printing to Tackle Labor Shortage

May 20, 2025 | News On Japan

NAHA - In Okinawa, the construction industry is exploring the potential of 3D printing as a solution to pressing labor shortages and to reduce project timelines. A demonstration event showcasing this emerging technology was held in the prefecture for the first time.

Last week, Kinshū Construction hosted a preview of a prototype 3D printer for construction in Okinawa City. Around 100 people attended the event, observing Japan’s only domestic manufacturer, Polyuse, demonstrate the process of printing actual structural components.

By integrating 3D printing with conventional construction methods, the technology is expected to significantly reduce construction time and help alleviate labor shortages — two persistent challenges in the sector.

One attendee expressed high hopes, saying, "This could revolutionize the industry by offering a completely different approach with faster build times and greater durability."

Kinshū Construction President Masahide Yamauchi commented, "With labor shortages and workstyle reforms already underway, I hope this becomes a catalyst for the industry looking five or ten years ahead."

Kinshū Construction aims to introduce 3D printing into its construction projects within the next two years.
