Direct answer: As of the latest available information, Shohei Ohtani and Yoshinobu Yamamoto are on the Dodgers, and Roki Sasaki joined their World Series roster, bringing the count of Japanese players on the Dodgers to three for that postseason context.

Details:

• Ohtani Shōhei (DH/P) is a core Dodger, continuing as a two-way standout, though his exact role in certain postseason situations can vary.

• Yoshinobu Yamamoto (RHP) has been the Dodgers’ top pitching contributor in the postseason, reinforcing the presence of Japanese talent on the club.

• Roki Sasaki (RHP) was added to the World Series roster as a bullpen option, expanding the Japanese representation on the playoff unit.

Context notes:

• Historically, the Dodgers have featured multiple Japanese players over the years, but in the 2025 postseason the official roster entries highlighted three Japanese-born players.

• Other Japanese players are part of MLB rosters around the league, but Sasaki’s inclusion marks the Dodgers’ current three-player count for that postseason run.

If you’d like, I can narrow this to regular-season active rosters, opening day rosters, or provide a quick comparison with other teams’ Japanese players in 2025.
