Yōsuke Ideguchi, born in Fukuoka on 23 August 1996 (age 30), is a compact Japanese central midfielder whose career has been shaped above all by Gamba Osaka. Early loan football helped harden him up, but it was at Gamba that he became properly established, making 127 league appearances and scoring 14 league goals across six seasons.
His best league return came in 2016, when he scored four times in 22 appearances for Gamba. That period remains the core of his career rather than a passing stop. The later moves matter, but they orbit the work he did there.
Celtic signed Ideguchi from Gamba Osaka in January 2022 for around £690,000. It was a relatively modest deal and, in the end, a relatively modest chapter. He left Celtic in January 2024, joining Vissel Kobe for around £860,000.
After Celtic, his route took in Vissel Kobe before he became more firmly associated again with Gamba Osaka. By 2026-27 he is with Vissel Kobe, wearing squad number 21, and remains involved in the first team: six J1 League appearances, one in the AFC Champions League Elite, and 16 in the J1 100 Year Vision League, where he has scored once.
Ideguchi’s career is not difficult to place. Gamba Osaka gives it its main shape, Celtic sits as a brief interruption, and Vissel Kobe is where he remains a regular presence in 2026-27.
