A picture shows the terraced rice paddies of Oyama Senmaida???reflected in morning sunshine in Kamogawa, Chiba Prefecture on May 5, 2021. Due to the mechanization and an aging of farmers, rice terraces disappeared in many places in Japan. However, the Oyama Senmaida has been maintained and currently, it is supported by the "owner system," which is a system that owners adopt a small plot of lands and experience rice planting and harvesting by themselves. Rice is the staple food of the Japanese.( The Yomiuri Shimbun via AP Images )
