Itodani, together with Akira Inaba, Masayuki Toyoshima and Akihiro Murata, is one of four Kansai-based young shogi professionals who are collectively referred to as the "Young Kansai Big Four" (関西若手四天王 Kansai Wakate Shitennō).[1]

Early life and education

Itodani was born in Hiroshima, Japan on October 5, 1988.[2] He learned how to play shogi when he was five years old[3] and he won the 1st and 2nd Elementary School Ōshō tournaments for grades 1 to 3 in 1995 and 1996 as an elementary school student.[4] He entered the Japan Shogi Association's apprentice school in October 1998 at the rank of 6-kyū as a protegee of shogi professional Nobuo Mori. He was promoted to 1-dan in February 2003[5] and to 3-dan in 2004.

From October 2004 to March 2005, he participated in the 36th 3-dan League finishing in fourth place with a record of 13 wins and 5 losses.[6] The following season in the 37th 3-dan League (April 2005 – September 2005), he finished in third place with a record of 12 wins and 6 losses and earned one "promotion point" towards professional status.[7] He obtained professional status and the rank of 4-dan in April 2006 after winning the 38th 3-dan League (October 2005 – March 2006) with a record of 14 wins and 4 losses.[5][8]

Itodani continued to attend private junior and senior high schools in Hiroshima prefecture while attempting to become shogi professional.[3] A year after turning professional, Itodani was accepted into Osaka University in 2007 majoring in philosophy.[9][10] He moved from Hiroshima to Minoh, Osaka and continued to pursue his education as an active shogi professional.[3] After completing his undergraduate studies in 2011, Itodani enrolled in the university's graduate school to continue his study of philosophy, particularly his research of the German philosopher Martin Heidegger. He received his Master of Arts in March 2017 becoming the first major-title winner to receive an advanced academic degree.[11]
