Thank you for your continued understanding and cooperation in the Tokyo Outer Ring Road Project.
In the vicinity of 2-chome Higashi Tsutsujigaoka, Chofu City, depressions in the ground surface and cavities in the ground have been confirmed, causing concern and inconvenience to everyone living along the outer ring road.
So far, the Committee of Experts has discussed the causes of accidents and measures to prevent recurrence, and has held briefing sessions for residents along the railway lines, with more than 500 people busy. We had people visit us.
We will continue to focus on monitoring the depressions and cavities and their surroundings, respond appropriately to inquiries from residents in the vicinity, and strive to eliminate anxiety. Thank you for your cooperation.
In addition, I would like to add that the construction will not be resumed immediately at this briefing session.
