We would like to offer our sincere apologies to residents for the inconvenience and anxiety caused by the ground surface collapse and cavity accident that occurred during construction of the Tokyo Outer Circular Road (Kanetsu to Tomei) in 2020, as well as the vibrations and noise during tunnel construction.
We recently held an open house for people living near the ground repair work sites, where we used panels to explain the status of the ground repair work and the progress of the Outer Ring Road Project.
In addition to the open house, we also provided a forum for the exchange of opinions between the target participants of the open house, Chofu city, and businesses.
