The Hiroshima Carp have announced uniform number changes for the 2027 season, with two players switching digits, Baseball Channel reported. Catcher Yasuki Mochimaru and outfielder Norihiko Nahara will wear new numbers when the new campaign begins.
Hiroshima’s Number Switches
The Carp made the official announcements on November 5. Catcher Yasuki Mochimaru is changing his number from 57 to 40. Outfielder Norihiko Nahara is switching from 92 to 57. The changes were confirmed by the team and published by Baseball Channel on November 6.
The club noted that the listed changes are for the transition from the 2026 to the 2027 season. Mid-season promotions from developmental rosters to the main roster, which often involve number changes, are not included in this list of announcements.
Other Clubs Expected to Follow
The official lists for the other 11 clubs—Yomiuri Giants, Hanshin Tigers, Yokohama DeNA BayStars, Yakult Swallows, Chunichi Dragons, Fukuoka SoftBank Hawks, Hokkaido Nippon-Ham Fighters, Orix Buffaloes, Tohoku Rakuten Golden Eagles, Saitama Se Lions, and Chiba Lotte Marines—are still pending.
Context for Number Changes in NPB
Uniform number changes in Japanese baseball are common events, often tied to a player’s career progression, the departure of a veteran, or team-specific roster management strategies. A new number can signify a new role or a fresh start for a player. The assignments are managed by each individual team, and the official announcements are closely followed by fans.
The process for assigning numbers can sometimes involve a waiting list for desirable digits, especially single-digit and double-digit numbers that are popular among players and fans. While teams have internal guidelines, the final decision rests with the club’s management and coaching staff.
What’s Next for Roster News
The next major checkpoint for official NPB offseason announcements will be the formal press conferences and media days for each team, typically held in January or February before spring training begins. These events are where clubs often unveil finalized rosters, coaching staff changes, and other key personnel decisions for the upcoming season. Fans and media will be watching for further updates on player movements and number assignments as the winter progresses.
