Around 8:20 AM, a 110 emergency call was received reporting that “construction machinery lifted by a crane truck made contact with power lines” in Koishikawa 1-chome. The crane truck tipped over and made contact with nearby structures, but there were no injuries. The Metropolitan Police Department is investigating the exact cause.

According to reports, a power outage occurred in the surrounding area. The Tomizaka Police Station is investigating the causal relationship.

Nearby residents reported hearing a loud “thud” and seeing utility poles and power lines shaking. “I thought it might be some major construction work, but then I saw the crane truck had tipped over.”

A man living on the top floor (5th floor) of the apartment building that was struck by the crane recalled, “Around 8:00 AM while I was eating breakfast, there was a loud thud and the apartment building shook. It was startling.” When he went out to the balcony, he could see the tip of the crane nearby. A smaller piece of construction machinery than the crane truck had fallen onto the road. Sparks were also coming from severed power lines. He made the 110 emergency call without fully understanding the situation. Noting there had been demolition work happening next door, the man said, “They were probably trying to move the machinery onto the site with the crane and lost balance. It’s fortunate there were no casualties.”

The site is located approximately 500 meters north of the Marunouchi Line.

It was originally established in 1931 to provide security for the nearby Koishikawa Korakuen Garden and the surrounding neighborhood. Today, it remains an active police box and is a beloved local landmark celebrated for its charming, anachronistic appearance.
