Japanese baseball, known as yakyū, is a popular sport in Japan, characterized by its unique culture and traditions. The professional league, called the Nippon Professional Baseball (NPB), consists of two main leagues: the Central League and the Pacific League. Each team plays a 143-game season, culminating in the Japan Series to determine the champion. The game is played similarly to American baseball, but it features distinct elements, such as the use of a smaller ball and a different style of pitching. Fans are known for their enthusiastic support, often engaging in organized cheers and songs for their teams, creating a vibrant atmosphere in stadiums.
