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 residents living near the areas where ground repair work is being carried out, where we used panels to provide individual explanations about the progress of the ground repair work.
In addition to the open house, we also provided a forum for the exchange of opinions between the target audience of the open house, Chofu City, and businesses.
