Hokkaido Nippon-Ham Fighters Hire Tsuyoshi Nishioka for the 2026 Season
The Hokkaido Nippon-Ham Fighters announced a major coaching staff reshuffle on October 16, hiring former Chiba Lotte Marines chief hitting and base-running coach Tsuyoshi Nishioka as their new infielder defense and base-running coach for the upcoming season, according to reports. The Pacific League club is moving swiftly to secure a new framework following a 3-0 sweep defeat to the Fukuoka SoftBank Hawks in the Climax Series final stage.
Defensive Rebuilding Under a Former Golden Glove Winner
Nishioka takes over a defensive unit that struggled significantly during the regular season. The Fighters recorded 88 errors—the worst mark across both Japanese professional baseball leagues—prompting the club to turn to Nishioka, who earned three Golden Glove Awards during his playing career with the Marines, as reported. Nishioka brings extensive coaching experience from his return to Lotte this past season, where he supported new manager Saburo and helped foster the development of young hitters like Pacific League hits leader Shogo Nishikawa.
Manager Tsuyoshi Shinjo’s Direct Request
Fighters manager Tsuyoshi Shinjo pursued Nishioka after the two appeared together in a YouTube project following the 2022 season, stating his desire to work with him. Shinjo specifically requested that Nishioka oversee mental conditioning, defense, and base running, leading to this unexpected outside appointment. Entering his sixth year at the helm, Shinjo emphasized that winning is the sole priority for the team’s upcoming campaign.
Atsunori Inaba Shifts to Lead Hitters
Alongside Nishioka’s arrival, farm team manager Atsunori Inaba will transition to the role of 1-year hitting coach, according to the announcement. While Nippon-Ham led both leagues with 177 home runs this past season, their 574 RBI fell 102 short of the pennant-winning SoftBank Hawks. Inaba, a Japanese Baseball Hall of Fame inductee who recorded 2,000 career hits as a player, will work alongside hitting coach Yokoo to boost run production without relying solely on home runs.
