Work by artists from all over the world is displayed in the world’s largest outdoor art festival held every three years in the rural Echigo-Tsumari region of Niigata Prefecture. It brings together more than 300 international artists in a natural setting and in years past, has included pieces by Britain’s Antony Gormley and American James Turrell. Interestingly, artworks can be found scattered across 200 villages, rice fields, empty houses and closed schools.
