The Iwami Ginzan silver mine was at the heart of a boomtown in the south-west of Honshu Island in the 1600s. But then its fortunes faded and a nearby forest drew in after the mine closed in 1923. By the 1970s, Iwami resembled a ghost town, and might have been forgotten, but for the Yen signs in the eyes of the tourist authorities. In 2007, after intense lobbying in Tokyo, a hole in the ground, of which most Japanese were entirely unaware, joined the ranks of the Taj and the Great Wall of China as a World Heritage Site.

So how did Iwami ever make the list? How does any site get "inscribed", to use Unesco-speak? If there is one fatal flaw in the whole process it is that countries submit their own nominations for inclusion. So when local businessman Toshiro Nakamura made it his life's mission to turn Iwami into a tourist attraction, the suits at the local prefecture were all ears. They used their links with diplomats in Tokyo to make a case for Iwami within Unesco's World Heritage Committee.
