Can you imagine an inhabited city where the water running through the the drain channels is so pure that beautiful koi fish can swim in it? Well, such a place exists on Japan’s Kyushu island. It’s called Shimabara, and it’s quite a sight to behold.
When the area around Shimabara was affected by the natural disaster known as the “1792 Unzen earthquake and tsunami” which killed 15,000 people, no one imagined that the dozens of fresh water springs that started gushing out would one day put the city on Japan’s travel map and inspire its now famous nickname – the “City of Water”. There are at least 60 known springs throughout Shimabara, making clean water one of the city’s most abundant resources. There is so much of it, in fact, that it flows through the drain channels along some streets. But that’s not even the craziest thing about this place; because the water is so pure, at one point authorities decided to put some koi carp in the channels, and Shimabara became the City of Swimming Carp.
