In brief
A soil collapse at a water‑pipe construction site in Anjo City, Aichi Prefecture, central Japan, buried two workers on Thursday, leaving one dead and the other missing. Local fire and emergency services rescued one worker who later died in hospital, while rescue operations continued for the second. Authorities are reviewing safety protocols and investigating the incident.
A soil collapse at a water‑pipe construction site in Anjo City, Aichi Prefecture, central Japan, buried two workers on Thursday, resulting in one fatality and a second missing person, Xinhua reported.
The incident occurred on a day when crews were excavating to install a new municipal water line beneath an existing roadway. Work was scheduled to finish within the week.
Local fire services received a distress call at approximately 1 p.m. local time, reporting that two workers had been buried under displaced earth.
Firefighters, supported by municipal emergency personnel, rushed to the site and began shoring up the unstable slope before deploying rescue machines.
Xinhua said that one of the buried workers was excavated in a single day, but was transported to a nearby hospital where he later expired.
Officials confirmed that the other worker remained missing. Firefighters and other responders had been conducting intensive search operations at 4 p.m. as the situation remained uncertain.
The site is managed by a regional construction company that has yet to release an official statement. A spokesperson for the company did not respond to a request for comment at the time of writing.
Anjo City officials said they were evaluating safety protocols after the collapse. Xinhua reported that the city's fire department had begun an internal review of equipment and training procedures.
Japan's Ministry of Land, Infrastructure, Transport and Tourism has issued a reminder to construction firms to reinforce soil stability during excavation, citing recent incidents in other prefectures.
Rescue crews set up a temporary medical station on the site to care for injured workers and to monitor for aftershocks. Local authorities did not announce any additional casualties at the time of the latest update.
The trench being dug was approximately 3 meters deep and 1.5 meters wide, designed to accommodate the 1.2-meter diameter main water line that will serve the district's growing water needs.
According to the city’s engineering office, soil composition in the area is a mix of loam and clay, which can make the ground unstable when saturated with water.
Workers reportedly had been monitoring moisture levels using handheld sensors, but the sudden rain that afternoon may have increased water content beyond safe thresholds.
Xinhua noted that the rescue work had been hampered by the lack of adequate ground‑penetrating equipment, making it difficult for teams to accurately locate the second victim.
In a statement, Anjo City’s mayor said that all necessary resources were being mobilized and that the safety of other workers was now a top priority.
The incident has sparked a debate among local contractors about the need for more rigorous soil-testing protocols before excavation begins.
Meanwhile, residents near the construction site reported hearing the collapse as a faint thud and were relieved when the fire department arrived promptly.
An emergency hotline was set up by the city, and administrative staff are offering counseling services to affected families.
Japan’s national emergency agencies have issued alerts to workers nationwide that emphasize proper training for soil stabilization and the importance of keeping a safe distance from excavation sites.
Construction code revisions are expected later this year, and the local council has scheduled a meeting with safety regulators to review the incident and propose changes to excavation guidelines.
