"It shakes in the middle of the night," "The smell of sewage reaches the house," the distressed cries of Yashio residents as the road collapse continues three months after the incident, despite a sharp decline in reports

Three months have passed since the road collapse caused by a broken sewer pipe on January 28 in Yashio City, Saitama Prefecture. The ground around the accident site is made of a weak layer of soil with fine grains that easily absorbs moisture, so it is difficult to repair it by injecting chemicals or driving steel sheet piles.
