kurokomon

Kurokumon is a river located in the Sabae city of Fukui Prefecture on the Japanese island of Honshu. It is a major tributary of the Kuzuryu River, and flows through a rural and mountainous area.

The name "Kurokumon" literally translates to means "black gate" in Japanese. This name is likely derived from the numerous dark-stained volcanic rocks and altering colors of the river's waters. However, the name may have a different origin and its exact meaning might not be well understood.

The river's course is approximately 20 kilometers long and flows through a largely mountainous area. Its waters support a moderate level of biodiversity, including various species of fish and other aquatic organisms.

In 1986, the Kurokumon was declared a first-order river, meaning it is a main channel that branches off directly from the larger Kuzuryu River or nearby mountain ranges. This classification makes Kurokumon integral to the local water system and a vital component in maintaining the ecosystem of the surrounding region.

The river plays an important role in provisioning the watershed with necessary water supplies and maintaining local hydrology. Its impact on the environment and supporting ecosystems might be significant due to its connection with other water sources and habitats.
