Colorful Koi Fish Swim Through the Street Drainage Canals in This Japanese City
In most cities, drainage canals are the last place you’d expect wildlife to thrive. However, in the city of Shimabara on Japan’s Kyushu island, the street’s gutters are so clean they are home to hundreds of koi carp. The unusual fish habitat is a product of the volcanic activities of Mount Unzen that resulted in the 1792 earthquake and tsunami.
