In 2011, it got recognized as that year's Japanese city with the fewest public gropings (only five incidents).
The city served as a coal mining base for almost a hundred years. In the 19th century, Mitsubishi (before they started making cars for Jackie Chan) used to run boats from Nagasaki to the island so workers could dig coal, until they realized that they could save a lot of money by just putting the miners and their families in concrete blocks on the island itself. Some 5,250 miners squeezed onto a 16-acre island, making it the most densely populated independent place on Earth, ever -- the equivalent of placing the entire world's population in Maine.
