This book is originally a western book, called in English “How Rabbit Stole Fire” by Joanna Troughton. (Possibly a British author?) It dates from 1979. It was taken from a North American Indian folk tale.
The Japanese title is “Ten no Hi o Nusunda Usagi.”
Literally: The Rabbit who Stole Heaven’s Fire.”
Atop a mountain, people live with fire. Rabbit goes, and using his cunning, steals it and takes it back to the other animals.
