A water pipe burst at a public housing complex in Sagamihara City, spraying water high into the air for approximately six hours [1].
The incident highlights the risks associated with aging infrastructure in residential zones, where deteriorating components can lead to sudden and significant utility failures.
The burst occurred in Midori-ku, Sagamihara City, Kanagawa Prefecture [2]. According to reports, the water spray began at about 13:30 JST on June 6, 2026 [3], and continued until shortly after 19:30 JST [1].
Witnesses described a massive jet of water that reached a height of about 10 meters [1]. Local residents and police responded to the scene as the flooding affected the housing complex grounds. One local resident said, "When I passed by, I thought, 'What is this?' I wondered what would happen since it just kept spraying."
Investigators said the cause of the failure was a valve on the water pipe that had deteriorated with age [4]. The aging component eventually detached, allowing the pressurized water to escape in a continuous plume for the duration of the event [4].
Emergency crews worked to isolate the leak and stop the flow of water. While the spray eventually ceased, the volume of water released over the six-hour period caused extensive surface flooding across the complex [1].

This incident underscores the critical need for proactive infrastructure audits in older public housing developments. When basic components like valves fail due to age, it can result in significant water waste and potential structural damage to surrounding residential areas.
