ABOUT US

Greetings

Iseki Kaihatsu Koki Co., Ltd. was founded in 1971 for the purpose of designing, manufacturing, and selling tunnel drilling and related construction machinery.
The Ankle Mole developed by our company has been widely used not only in Japan but also around the world for the development of social infrastructure such as water supply and sewage, electricity, and telephones.
We are also the only tunnel drilling manufacturer that has a construction department that carries out tunnel excavation work, and have been tackling difficult construction projects with a one-stop service from construction planning.
In 2022, our company became a group company of the Exeo Group.
In the future, we aim to combine the Exeo Group’s information and communications technology with our trenchless techniques to create innovation and contribute to the world.
