The fictional Hyakujōshima is the location of the Tongari family's vacation home. A family of kabocha farmers lives there and takes care of the place. The island is sparsely populated because many people move from it. It is accessible from Tokyo via airplane and ferry.
Two fictional schools are mentioned in the series: Hyōno Elementary and Takao University. Hyōno Elementary is the public school Kiteretsu and his friends attend. During summer vacation, one of the lunch ladies uses the school to teach piano lessons. There is also a rumor that the school is haunted.
