5.300 de oameni au fost duși pe o insulă mică de forma unui cuirasat, lângă Nagasaki, și au rămas acolo 25 de ani. Apoi totul s-a oprit

In 1959, a Japanese coal mining company densely populated Hashima Island with 5,259 people, making it the most densely populated place on Earth. Known as Gunkanjima, the island housed various facilities for miners, including schools and shops. After the coal mine closed in 1974, the island was abandoned, leading to rapid deterioration of its structures. UNESCO recognized Hashima as a heritage site in 2015, but disputes over forced labor during its mining era persist between Japan and South Korea. Conservation efforts are lacking, and experts warn that the ruins require specialized care to prevent further decay.
