The Biggest Painting in the World 2020 in Noboribetsu City was completed by sewing together 2 paintings by the children of Koropokkuru-no-mori Kindergarten, 1 each by the pupils of Noboribetsu Primary School, Horobetsu Higashi Primary School, and Horobetsu Primary School. We had a ceremonial photo taken in front of the crater of Noboribetsu Hot Springs with the mothers who did the sewing.
