Thank you very much for your understanding and cooperation in the Tokyo Outer Ring Road Project (Outer Ring Road Project).
We sincerely apologize for causing great inconvenience and anxiety to residents due to the ground surface cave-in/cavity accident that occurred in Chofu City in 2020 during the construction of the outer ring project.
This time, we held an open house for those who live in the vicinity of the Tomei JCT ramp shield tunnel construction site, where individual explanations using panels etc. will be held. At this open house, we will discuss "recurrence prevention measures and regional safety and We explained about efforts to increase peace of mind" and "future excavation".
In addition, we also set up a forum for exchanging opinions between residents who wish to participate and business operators.
In addition, we also asked for individual consultations regarding the site.
