While for "Tsumiki no Ie", Katō created the work out of paper drawings and 2D computer graphics. The animation was painstakingly drawn by hand, meaning it took about seven months to complete the 12-minute film. It tells the story of a grandfather's memories as he adds more blocks to his house to stem the flooding waters. The Academy of Motion Picture Arts and Sciences announced that Kunio Kato's "Tsumiki no Ie" was nominated for Best Animated Short Film and won the award. The animation has already won a number of awards, including the Annecy Cristal and Junior Jury Award at the Annecy International Animated Film Festival and Market, and the Hiroshima Prize and Audience Prize at the Hiroshima International Animation Festival. Below is a description of Tsumiki no Ie from Annecy's website:
"It is difficult to keep the house made of blocks out of the water. The grandfather who has lived in it has been constantly adding to it as the water level rises. This is the story about his family memories."
