Yōsuke Ideguchi, born on 23 August 1996 (age 29) in Fukuoka, is a compact Japanese central midfielder now with Vissel Kobe, wearing squad number 21.
His career is still shaped most strongly by Gamba Osaka. Across six seasons there, he made 127 league appearances and scored 14 league goals, with 2016 his most productive league campaign: four goals in 22 games. Early loan football formed part of his development, but Gamba was where he became a proper first-team player rather than just another promising midfielder passing through.
Celtic signed him from Gamba Osaka in January 2022 for around £690,000. It was a move that looked sensible enough on paper, but his time in Glasgow never really settled into anything substantial. In January 2024 he left Celtic for Vissel Kobe for around £860,000.
Vissel Kobe has given him a steadier platform since then. In 2025 he has remained a regular first-team presence, making 30 J1 League appearances and scoring once, along with nine AFC Champions League Elite appearances and three goals, plus 16 J1 100 Year Vision League games and one goal. Across all competitions for Vissel Kobe, he has made 55 appearances and scored five goals.
Ideguchi’s career has moved through Celtic and Vissel Kobe, but Gamba Osaka remains the main body of work. He is not a footnote, nor a star turn; he is an established Japanese midfielder whose best football has been built on regular games and clear responsibility.
