TL;DR
Chigirishima Island in western Japan is a major site for lead production, supplying almost 50% of Japan’s lead. The island remains active with industrial facilities, contrasting with nearby wooded areas. This development underscores Japan’s reliance on this small island for critical mineral supplies.
Chigirishima Island in western Japan’s Seto Inland Sea is confirmed to produce nearly 50% of Japan’s lead supply, with its industrial facilities still operational. This makes it a critical site for Japan’s mineral industry and supply chain security, especially as global demand for lead remains high.
Chigirishima, originally two islands now fused into one through landfilling, hosts extensive industrial structures dedicated to lead processing. According to Nikkei Asia, the island’s operations are still active, supplying approximately half of Japan’s lead production. The island’s silhouette resembles a floating ship, standing in stark contrast to the lush, wooded neighboring Ikunoshima Island.
While the island’s industrial activity is confirmed, details about the scale of its operations, the number of facilities, and the workforce involved remain limited. Experts note that Chigirishima’s lead production is vital for Japan’s manufacturing sectors, including electronics and automotive industries, which rely heavily on lead for batteries and other components.
Environmental concerns and regional development policies are ongoing topics of discussion, but there is no indication that operations on Chigirishima have been scaled back or halted. The island’s strategic importance is underscored by its continued activity amid broader shifts in global mineral sourcing.
Implications of Chigirishima’s Lead Production for Japan’s Industry
The fact that nearly half of Japan’s lead is produced on Chigirishima underscores the island’s critical role in the nation’s supply chain, especially amid global supply chain disruptions and increasing demand for minerals used in electronics and batteries. Japan’s reliance on this small island highlights vulnerabilities in its resource independence and raises questions about environmental and safety standards.
Maintaining operations on Chigirishima is essential for Japan’s domestic industries, but it also draws attention to the environmental impact of such concentrated industrial activity. The island’s ongoing production emphasizes the need for careful resource management and sustainable practices to ensure long-term supply stability.

Historical and Regional Background of Chigirishima’s Lead Industry
Chigirishima Island, located in Japan’s Seto Inland Sea, was originally two separate islands before landfilling merged them into a single landmass with industrial facilities. Its industrial development is linked to Japan’s post-war economic growth, with the island becoming a key site for mineral processing.
While the island resembles Nagasaki’s Battleship Island in appearance, it remains operational and actively produces lead, unlike some other industrial sites that have been abandoned or converted. The region has long been a hub for resource extraction and processing, with regional policies supporting its continued industrial activity despite environmental concerns.
Japan’s overall lead consumption has remained steady, with domestic production on Chigirishima playing a major role. The island’s strategic importance has grown amid global supply chain uncertainties, making it a focal point for resource security.
“Chigirishima’s industrial facilities are still fully operational, and the island supplies nearly 50% of Japan’s lead. Its strategic importance cannot be overstated.”
