Ayumu Seko Club Career
Cerezo Osaka gave Seko his first senior platform, and by the end of 2021 he had built enough credibility to move to Europe.
Grasshoppers signed him in January 2022 on a three-year deal, and he quickly became a regular in the Swiss Super League through his reliability and positional discipline.
His time in Switzerland prepared him for a more demanding league move and gave him much steadier top-flight experience than he had in Japan.
Le Havre signed Seko in July 2025 on a contract through June 2027, giving the club a defender with experience across centre-back and midfield zones.
Capology lists his current deal at an estimated €14,038 gross per week, which reflects a stable Ligue 1 contract even if it is not a star-level wage.
That matters for Japan because he now arrives from a top-five-league environment where defensive concentration is tested every week.
