The Phoenix Prize was a new introduction to the 4th International Junior Koi Show.
The Phoenix project started in Nagaoka after the 2004 Chuetsu Earthquake. Each year at the Nagaoka Matsuri which takes place in August, the largest and most impressive part of the display is unquestionably the Phoenix.
