Yakult Veteran Masanori Ishikawa to Retire After 25th NPB Season
Masanori Ishikawa, 46, will retire after the 2026 season, ending a 25-year NPB career with Yakult; a retirement press conference is scheduled for September 2.
Masanori Ishikawa announced he will retire at the end of the season, the Tokyo Yakult Swallows and team sources confirmed on September 2. The announcement follows an August 27 outing in which Ishikawa left with a left-shoulder injury and was unable to secure a win in his 25th season.
Club confirms retirement and sets press conference
Yakult officials disclosed on September 2 that Ishikawa, the oldest active player in Nippon Professional Baseball, has decided to step away from playing after this season. The club said Ishikawa will appear at a formal press conference later that day to discuss his decision.
The retirement ends a career that began more than two decades ago and will be formally acknowledged in interviews with team personnel and league representatives at the scheduled briefing. The club did not provide details about post-retirement plans at the time of the announcement.
Final appearance marred by shoulder injury
Ishikawa’s lone appearance this season came on August 27 at Meiji Jingu Stadium against the Yomiuri Giants, when he made his first outing and first start of the year. He recorded only one out while allowing five hits and six runs before departing with discomfort in his left shoulder.
The short outing meant Ishikawa was unable to extend the streak of seasons with at least one win to 25, a milestone he had pursued in his final campaign. Team medical staff classified the issue as an injury to his left shoulder that prompted his early exit from the game.
Season marked by extended time in the minors and injuries
Ishikawa began the 2026 season in the Swallows’ second team after reporting to camp in February and did not return to the top roster until late August. He suffered an upper-body injury during spring appearances, and persistent conditioning problems limited his effectiveness in the minors.
Those setbacks kept his return to the first team from occurring earlier in the season, and Yakult officials acknowledged his rehabilitation and performance did not reach the levels that characterized his earlier career. The delayed promotion underlined the physical toll of a long pitching career and helped shape his decision to retire.
Long career with notable achievements and records
A native of Akita Prefecture, Ishikawa rose through Akita Commercial High School and Aoyama Gakuin University before joining Yakult in the 2001 draft under the club’s free acquisition slot. He broke into the NPB spotlight in 2002, posting 12 wins and earning the Pacific League’s top rookie honors.
Ishikawa established himself as an ace through the mid-2000s, producing five consecutive seasons with double-digit wins from his rookie year and capturing the league ERA title in 2008 with a 2.68 mark. He started Opening Day nine times, contributed to three league championships and was part of one Japan Series-winning squad.
Career totals and standing in NPB history
Through the end of the 2025 season Ishikawa had extended a run of consecutive seasons with at least one victory to 24, the longest such streak in professional Japanese baseball at that time. Over his career he made 551 appearances and compiled a win–loss record of 188–194 with a 3.94 earned-run average.
Those totals placed him among the most durable pitchers of his generation, and his streak of consecutive seasons with wins was widely cited as a measure of consistent availability and competitiveness. Club officials and teammates have praised his longevity and role as a veteran presence in the clubhouse.
Reactions from the club and baseball community
Yakult teammates and former colleagues were brief in public remarks as the announcement was still unfolding, with several players expressing respect for Ishikawa’s contributions and expressing anticipation for the team press conference. The Swallows are expected to coordinate tributes and acknowledgments as the season moves to its conclusion.
Observers noted Ishikawa’s career as emblematic of a workhorse pitcher who adapted across eras of play and maintained a presence on the mound into his mid-40s. The timing of the retirement announcement allows the club and fans to mark his final season while he is still active on the roster.
Ishikawa’s formal press conference on September 2 will provide further detail on his reasons for retiring and any intentions he may have regarding coaching, broadcasting or other roles within baseball. Fans and colleagues will watch closely as one of NPB’s longest-serving pitchers closes his playing chapter.
