Izumi Kobayashi grew up in a family of accomplished Go players. She has joked that she first played Go in her mother's womb.

Her mother was Reiko Kobayashi née Kitani (1939-1996), 6 dan, who won the All-Japan Women's Championship several times. She became a professional go player in 1995, and was promoted to her current rank, 6 dan, in 2004. She is married to Cho U, one of the top players in Japan.
