Kenichiro Isozaki (born 1965) is a Japanese novelist from Chiba Prefecture. After graduating from the School of Commerce at Waseda University, he began writing while working for a major trading company and made his literary debut in 2007 when "Kanjin no Kodomo" received the Bungei Prize. His fiction moves rapidly between narrators, places, and historical periods, joining private memories to public events through long, continuously unfolding sentences. He received the Akutagawa Prize for "Tsui no Sumika" and the Izumi Kyoka Prize for Literature for "Ōko Raikon." His representative novel, "Nihon Mōmai Zenshi," won the Tanizaki Junichiro Prize and traces events embedded in postwar Japanese memory—including the Osaka Expo, the return of a former soldier, the birth of quintuplets, and an airline disaster—while depicting from multiple perspectives the lives of otherwise unknown people unfolding around them.
