Yamakoshi

Yamakoshi is a mountainous village in Niigata Prefecture, Japan, located approximately 40 kilometers from Nagaoka City. The area was originally an independent village until it merged with Nagaoka in 2005, following the devastating Chūetsu earthquake of 2004 that destroyed much of the community and forced complete evacuation. The village's remarkable recovery and return of residents has made it a symbol of rural resilience in Japan.

The region is internationally recognized as the birthplace of Nishikigoi, the ornamental colored koi carp that have become synonymous with Japanese culture. Yamakoshi farmers began selectively breeding these fish over 200 years ago, transforming them from plain carp into the vibrant living jewels now prized worldwide. The village remains one of Japan's primary koi breeding centers, with numerous farms still operating in the traditional manner. The area also preserves tanada, spectacular terraced rice paddies that cascade down the steep mountain slopes, creating striking geometric patterns that change with the seasons.

Visitors can tour active koi farms where breeders explain the meticulous selection process and demonstrate how these fish are raised in mountain spring water. The Yamakoshi Bullfighting Museum documents the village's centuries-old tradition of ushi no tsunotsuki, a unique form of bullfighting where two bulls push against each other in tests of strength rather than fights to injury. These exhibitions, held several times yearly at a dedicated ring, represent one of Japan's most unusual cultural traditions. The village's traditional thatched-roof farmhouses, some converted into museums and guesthouses, offer insight into historical mountain life and the architectural techniques developed to withstand heavy snowfall.

Yamakoshi receives over 7 meters of snow annually, making it one of Japan's snowiest inhabited areas. The village is accessible by car from Nagaoka Station via Route 17, a journey taking approximately 50 minutes. Local buses operate from Nagaoka but run infrequently, making private transport advisable. Most koi farms welcome visitors free of charge, though calling ahead is recommended. The bullfighting museum charges a small admission fee of around 500 yen.
