Northern Japan is know for rice production. After a harvest, rice straw—or wara—is recycled to improve the soil,or it is woven into giant sculptures. For nine years Uwasekgata Park has hosted the Wara Art Festival, teaming up with creatives to create creatures from rice straw. Schools send art students to Niiigata to assist with the sculptures that remain on display well into the fall.
