This Middle Jomon Period (c. 3,500?2,500 BC) clay figurine (dogu) was excavated from Katsurano site. This clay figurine could be chronologically situated at the beginning of the Middle Jomon Period. This clay figurine is an almost-complete piece, missing only some of its toes and an ear. The head shape of this clay figurine looks like the water sprite from the Japanese folklore called “kappa”. The nickname of this clay figurine was selected as “Misakappa” based on school-wide poll of students at Misaka Higashi Elementary School (“Misaka”+“Kappa”=“Misakappa”) where Katsurano site is located.
