The Samurai Japan dugout finally has an MLB résumé in it

Nippon Professional Baseball made it official on Saturday in Tokyo: Tadahito Iguchi is the new manager of Samurai Japan. The 51-year-old is the first person to hold the job after playing in Major League Baseball. The mandate runs through the 2028 Los Angeles Olympics. The vacancy opened in March, when Hirokazu Ibata resigned after Venezuela ended Japan’s World Baseball Classic in the quarterfinals — the first time the defending champions failed to reach a WBC semifinal.

The résumé is why the hire travels beyond a coaching bulletin. Iguchi won Olympic silver with Japan as a university player in Atlanta in 1996. He collected Japan Series titles with Daiei and Lotte, then four MLB seasons with the White Sox, Phillies, and Padres — including the 2005 World Series with Chicago, when he became the first fully Japanese-born position player to win the title. He managed the Chiba Lotte Marines from 2018 through 2022, a stretch that included two second-place finishes and the early professional years of Roki Sasaki, now a Dodger alongside Shohei Ohtani and Yoshinobu Yamamoto.

Iguchi’s first assignment is the Asia Professional Baseball Championship in November, a younger-heavy regional event. The real gate for LA28 is the 2027 Premier12: finish as Asia’s top team there and Japan books an Olympic berth; miss it and the path slides into a final qualifier before March 2028. At his introductory press conference he called an Olympic medal the first goal, said he was prepared for a hard road to qualification, and framed Japan’s edge as team baseball rather than stacked individual talent alone.

The MLB file is the other half of the job. LA28 is the first Games where active major leaguers may be cleared to play baseball, though hotel, insurance, and participation rules between MLB and the players’ union are still unsettled. Ohtani has said he wants to play if the window opens. Iguchi, asked about Japan’s major leaguers, called them “Japan’s treasure” and said he wants them in the Olympics pulling the team — and plans to contact MLB players early, including personal debriefs from the last Classic. A manager who has worn an MLB uniform is not a guarantee those calls land. It is the clearest staffing answer Japan has given to a roster that increasingly lives in American clubhouses for nine months a year.

For readers who watched Japan’s WBC end in Miami, Saturday is the institutional response. The pipeline that put Ohtani, Yamamoto, and Sasaki in Dodger blue now has a national-team skipper who has walked both sides of the posting door. The November Asia championship will look like a soft open. Premier12 will not. LA28 is the date on the contract.
