Company Overview

  • Pioneers Challenging New Frontiers and Realizing Dreams
    JIMT inherits that desire to create the future of underground development.
  • JIM TECHNOLOGY Corporation (JIMT) is a company that was founded through the merger of the tunnel excavation businesses of IHI Corporation (IHI), JFE Engineering Corporation (JFE), and Mitsubishi Heavy Industries, Ltd. (MHI).
Tunnel excavation construction is required for creating large-scale infrastructure, such as railways, subways, expressways, and underwater tunnels.
Shield machines require a high degree of excavation technology and machine performance to be able to handle a variety of environments having different types of geology and topography.
JIM Technology was established in October 2016 through a merger of the tunnel excavation businesses of IHI, JFE Engineering, and MHI
in order to provide more value-added products and services in the tunnel excavation business sector.
Our aim is to leverage our greatly improved technologies and design/production capabilities
so that we can transition from a leading company inside Japan to a leading company in global markets.
