Aogu Tanaka (born 1992) is a Japanese writer and sports journalist from Chiba Prefecture. After graduating from Sophia University and working for an editorial production company, he joined Bungeishunju’s NumberWeb editorial team in 2021, writing reported features and nonfiction on high school baseball, NPB, MLB, and other sports. His first book-length work of nonfiction, "Kantoku, Kami ni Naru: Ikeda Kōkō, Kioku no Shōtotsu," investigates Tatsuya Tsuta, the celebrated coach who led Tokushima Prefectural Ikeda High School to national prominence at Koshien in the 1980s. Drawing on interviews with former players, family members, and others, the book reconstructs conflicting memories of a coach revered as a high school baseball legend while examining the money, personal relationships, and tensions behind Ikeda’s celebrated era.
