In professional Japanese baseball, there are typically nine innings, just like in Major League Baseball (MLB) in the United States. However, there are some variations in the length of games depending on the league and the level of competition.
In the Nippon Professional Baseball (NPB) league, which is the highest level of professional baseball in Japan, games are typically nine innings long. However, if the game is tied after nine innings, play will continue until there is a winner, with the game ending once one team scores more runs in an additional inning.
In addition, the Central League and Pacific League, which are the two leagues that make up the NPB, have slightly different rules regarding extra innings. In the Central League, if the game is still tied after 12 innings, the game will be declared a tie. In the Pacific League, however, games can continue indefinitely until there is a winner.
Overall, while the number of innings in Japanese baseball is generally the same as in American baseball, there are some variations in the rules that can affect the length of games and the outcome in the event of a tie.
