Toko GeoTech Co., Ltd. (Location: Chuo-ku, Tokyo; President and CEO: Mutsuo Yoshii), a member of the Takamatsu Group specializing in slope protection and ground improvement, and Aerosense Inc. (Location: Kita-ku, Tokyo; President and CEO: Kotaro Sabe, hereinafter referred to as Aerosense) have jointly developed a vegetation material spraying method using a large wired power drone for slope spraying (Method name: Green Impulse, hereinafter referred to as Green Impulse). A model construction was carried out at a construction site in Kitashitara District, Aichi Prefecture, from May 19 to May 22, 2026.
This construction was performed as part of the Shitara Dam related project, commissioned by the Shitara Dam Related Business Branch Office of the Shinshiro Shitara Construction Office, Aichi Prefecture.
Green Impulse is a vegetation material spraying method that, despite being a large drone, can perform high-altitude work for extended periods using wired power supply without the need for heavy machinery like cranes. The method of spraying artificial soil mixed with seeds and fertilizers by drone is unprecedented and represents the world's first initiative* (1) in actual construction sites. The introduction of this method is expected to improve the safety of workers in slope construction, address the worsening labor shortage, expand the range of constructible areas, and significantly improve work efficiency and reduce manpower.
In this model construction, specialized operators were assigned to perform the work, but we are advancing technological development with the aim of achieving fully automated navigation for construction. In the future, we will accelerate verification for practical application with a view to mass production and introduction to various regions within Japan.
In the future, we aim to contribute broadly to the development of safe and sustainable social infrastructure by applying it to other spraying construction methods such as mortar spraying, for disaster recovery work including mountain slope collapse sites, and through utilization under more challenging construction conditions.
Toko GeoTech and Aerosense will continue to promote the automation of construction sites with the aim of improving the safety of slope work and resolving the labor shortage.
