I'll talk about Korean baseball. The professional league is KBO professional baseball league, where KBO stands for Korea Baseball Organization. Until now, there are 8 teams, LG Twins, Samsung Lions, Kia Tigers, SK Wyverns, Doosan Bears, Nexen Heroes, Hanwha Eagles, and Lotte Giants. All the clubs get supports from big corporations. During season, each team plays 133 games. After the season is done, play-off takes place. 3rd team and 4th team play games and have to win 3 games first. Then, winner of the matches play against 2nd team. They also have to win 3 games first. Then, in Korean Series, 1st team and the winner of play-off plays against each others to win 4 games first. This year's total number of tickets sold out, excluding post season, was over 5.5 million. This is the largest since the first year of professional baseball league.
Not only league, but the national team is also very strong. In Olympics and WBC, World Baseball Classic, Korea has achieved championships. Also, Korea's rival is always Japan just as Japan's rival is always Korea. This rivalry is in all sports between Korea and Japan. While Japan is strong in pitching, Korea is better in batting.
