Koi Fishes Thrive In Clean Drains Of Shimabara City of Japan

Japan, known for its technological advancements and impeccable cleanliness, has taken city planning to a whole new level. In the city of Shimabara, located on the island of Kyushu, the drainage canals are so pristine that they have become home to hundreds of colorful koi fish.

These canals, which would typically be associated with waste and debris, are a stunning example of Japan’s commitment to maintaining a clean and healthy environment.

The Origins of the Koi Habitat

The presence of koi in Shimabara’s drainage canals is a result of the devastating 1792 Unzen earthquake and tsunami, which claimed the lives of over 15,000 people.

In the aftermath of this tragedy, an abundance of fresh water springs emerged, providing a constant flow of clean water through the city’s drainage channels.

In 1978, local authorities made the decision to release koi fish into the 100-meter-long waterway, creating a unique and beautiful attraction.
