Japan’s First Successful Test Blasting Using Wireless Electronic Detonators in Road Tunnel Construction

Taisei Corporation successfully conducted a test blast using wireless electronic detonators in a road tunnel construction project. The trial took place in late May 2025 at the Shin-Ozoki Tunnel construction site on National Route 13, commissioned by the Tohoku Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism.

This achievement marks a significant advancement in tunnel construction, enhancing safety and productivity by eliminating the need for manual wiring of detonators near the tunnel face.
