Water Meters Stolen in Vacant Japanese Public Housing as Copper Prices Rise

The theft of water meters used to measure household water consumption is spreading across Japan. Authorities suspect many water meters are being stolen for resale because they contain copper, whose price has climbed sharply in recent years. 50) to ¥2,000 when resold.

Local governments are urging residents and scrap metal dealers to stay alert. Officials say effective countermeasures remain elusive, particularly because many thefts target vacant apartments in public housing complexes and other multiunit buildings. The Japan Times reported that the pattern has become widespread enough to prompt coordinated appeals from municipal authorities.

In Shizuoka Prefecture, 449 water meters were reported stolen in March and April. The 449 stolen water meters in Shizuoka Prefecture came from municipal housing complexes and other properties across seven cities, including Shizuoka and Fujieda. All of the thefts in Shizuoka Prefecture occurred in vacant units and were discovered only after water leaks and other problems emerged.

The timing of the discoveries meant that many thefts went unnoticed for weeks or longer. Thieves apparently removed the meters from empty apartments without immediate detection, leaving pipes exposed. Water leaks eventually drew attention from maintenance crews or neighboring residents, at which point the missing meters were recorded.

Copper prices have climbed sharply in recent years, giving scrap metal dealers an incentive to accept the devices despite their specialized origin. The Japan Times reported that the resale value, while modest per unit, becomes attractive when multiplied across hundreds of thefts.

Authorities have grown concerned that the combination of high copper prices and easily accessible vacant properties is fueling organized scavenging.

The seven cities affected in Shizuoka Prefecture illustrate how the problem crosses municipal boundaries within a single prefecture. Shizuoka and Fujieda are among the locations where housing complexes lost multiple meters in a short period. Officials have begun sharing data across city lines in hopes of identifying patterns, though concrete leads remain scarce.

Public housing operators face particular difficulties because vacant apartments are often kept in minimal maintenance mode until new tenants arrive. Without regular inspections, the absence of a water meter can persist undetected. The Japan Times reported that this vulnerability has turned multiunit buildings into repeated targets.

Local governments have responded by issuing public notices asking residents to report suspicious activity around utility areas. Scrap metal dealers have been asked to scrutinize any sudden influx of water meters and to document sellers. Yet officials acknowledge that these appeals have so far failed to produce meaningful deterrence.

The Japan Times reported that effective countermeasures remain elusive because the devices are small, valuable only for their copper content, and easily removed with basic tools. Police have opened investigations in the affected Shizuoka cities, but the sheer volume of cases and the lack of witnesses in vacant buildings complicate efforts.

No arrests have been announced in connection with the March and April thefts.
