Hifumi Katō (加藤 一二三, Katō Hifumi; January 1, 1940 – January 22, 2026) was a Japanese professional shogi player who achieved the rank of 9-dan. During his career, he won the Meijin, Tenth Dan, Ōi, Kiō and Ōshō major titles. He also held the record for being the youngest to have been awarded regular professional status at age 14 years and 7 months until Sōta Fujii broke it at age 14 years and 2 months in 2016. Since his given name is written using the kanji characters for the numbers "one","two" and "three", Katō was known to his fans by the nickname "Hifumin" (ひふみん). Source: Wikipedia (en)
