An anonymous donor gave Osaka gold bars worth ¥560 million (about $3.6 million) to fund repairs to the city’s aging water‑pipe network. The 46‑lb gift was delivered to the Osaka City Waterworks Bureau in November 2025 and will be used as the donor requested, Mayor Hideyuki Yokoyama said. The donation follows a deadly Jan. 28, 2025 sinkhole that highlighted vulnerabilities in the city’s infrastructure; Osaka needs to renew roughly 259 km (160 miles) of mains, and replacing a 2‑km segment costs about ¥500 million.

An anonymous benefactor has donated gold bars valued at ¥560 million (about $3.6 million) to the city of Osaka to be used specifically for repairing aging water pipes, city officials said.
The bullion — weighing roughly 46 pounds (about 21 kilograms) in total — was handed to the Osaka City Waterworks Bureau in November 2025, Mayor Hideyuki Yokoyama told reporters on Feb. 19. “It’s a staggering amount, and I was speechless,” he said, pledging that the city will honor the donor’s request to devote the funds to water infrastructure upgrades.

Why the Gift Matters
The donation comes as concerns about Osaka’s waterworks have intensified following a catastrophic sinkhole on Jan. 28, 2025, that swallowed a truck and killed a 74‑year‑old driver. Rescue operations were complicated as the hole widened to at least 131 feet across and 50 feet deep; search efforts were suspended on Feb. 9 and the driver’s body was recovered on May 1. Authorities later linked the sinkhole to damaged sewer infrastructure, according to The Associated Press.
Osaka — a major port and commercial center on Honshu with about 2.8 million residents — recorded 92 cases of water‑pipe leaks beneath city roads in the fiscal year ending March 2025, Eiji Kotani of the city’s waterworks bureau told AP. The city estimates it needs to renew roughly 259 kilometers (160 miles) of water mains.

“Tackling aging water pipes requires a huge investment, and I cannot thank enough for the donation,” Mayor Yokoyama said.
Costs and Impact
According to city figures, replacing a 2‑kilometer (1.2‑mile) segment of water main costs about ¥500 million (roughly $3.2 million). While the gold donation does not cover the entire modernization program, it represents a substantial contribution toward at least one major replacement project and highlights the urgency of upgrading decades‑old infrastructure built during Japan's rapid postwar expansion.
The city has said it will convert the gold to funds and apply them as requested by the donor to accelerate pipe replacements and related repairs.
