Echigo-Tsumari Art Triennale is one of the largest art festivals in the world and is held once every three years in the Echigo-Tsumari region since 2000.

The Triennale provides an opportunity to present projects and initiatives developed in the Echigo-Tsumari Art Field. These projects aim to reveal existing assets of the region using art as a catalyst, rediscover their values, communicate these to the world and find a way to revitalize the region.

The Triennale has been held for five times since 2000 and the preparation for the 2015 event is underway.
