Early studies based on time-group of house counts from western Kanto (Saitama, Tokyo, and you will Kanagawa Prefectures) suggest a period from around three periods away from inhabitants go up and you may slide with different levels of magnitude. A great deal more specifically: 1) an increasing trend into second half of Early Jomon period; 2) an abrupt decrease in this new transition in order to Middle Jomon; 3) a people restriction towards second half of the Middle Jomon; 4) then followed again because of the a-sharp decline in this new change toward Late Jomon; and you will 5) another less rise and you will slip from inside the center part of the fresh new Late Jomon.
