Students at the Oarai Girls' School received an announcement about the closure of their school by the head of the Ministry of Education. Until their new school is decided, they have to study at a temporary school. It was Kamioka Primary School, which served as a model for this provisional school. It is located near the Isosaki shrine in the television work, but in reality it is a two hour drive from Oarai. It is possible to visit there only on weekend.
