Nippon Professional Baseball, or NPB, oversees Japan’s top level of professional baseball. Its first-team competition has twelve clubs split evenly between the Central League and the Pacific League. If you are just picking a team to follow, find out which league it plays in. That tells you which standings to watch and makes the autumn matchups easier to follow.
A pennant and a national title are separate prizes
Clubs compete for position in their own league during the regular season and play teams from the other league during interleague play. Late in the season, the gap between third and fourth can be as interesting as the race for first. Each league sends its top three teams to its Climax Series.
The second- and third-place teams play first. The winner advances to face the first-place team. The two Climax Series winners then meet in the Japan Series. A club that finishes second or third can still end the year as national champion. When you look back at a team's record, pay attention to whether it won the league pennant, the Japan Series, or both.
Let a ballpark help you pick a team
The Hanshin Tigers play at Hanshin Koshien Stadium, the Hiroshima Toyo Carp at Mazda Stadium, and the Hokkaido Nippon-Ham Fighters at ES CON FIELD HOKKAIDO. A club’s name gets you to the right region, but the actual address can tell you a little more. Koshien Stadium is in Nishinomiya, and the Fighters’ ballpark is in Kitahiroshima.
Try following one club through a home game and a road game. You’ll hear the cheers coming from a different part of the park, and the team you’re watching will switch from batting second to batting first or vice versa. If the standings leave you torn between two clubs, see which ballpark makes you want to watch another game.
Follow a club through a stretch of the season
Early in the season, try watching a club play the same opponent on consecutive days. Did a hitter who did damage on an inside pitch get another one in the next game? Did the catcher change how he set up? The standings compress those adjustments into wins and losses. Watching a few games in a row gives you a better chance to notice what changed, including the work of relief pitchers and players coming off the bench.
Interleague play gives fans a reason to get to know teams on the other side of the league split. If you normally follow the Central League, a Pacific League pitcher you first see in an interleague matchup might become someone you keep an eye on when the teams return to their league schedules. Think of those games as part of the regular season. The elimination rounds come later.
Translate the standings into a postseason bracket
Suppose your club finishes third. It will play the second-place club first, and if it advances, it will face the league winner. Under the Central League’s 2026 format, the second-place club hosted the first stage, the first-place club hosted the final stage, and the first-place club normally began that stage with a one-win advantage. A rule introduced in 2026 increases the advantage to two wins and makes the stage a race to five wins if the teams finished at least ten games apart or if the first-stage winner finished below .500. Finishing higher changes both the opponent and the conditions under which a club plays.
The Japan Series goes to the first team to win four games. Games can end in ties under the series rules, so “first to four wins” is a more accurate shorthand than assuming the competition always fits into a maximum of seven games.
What you can see from different seats
From the infield side, look at how the middle infielders shift once a runner reaches base. In the outfield, you may have a better view of an outfielder’s first step on a ball hit over his head. On a broadcast, most of your attention is drawn to the pitcher and batter. When a wide shot comes up between pitches, use it to see where the defenders are starting and guess what will happen if the batter hits the ball their way.
If you are following from overseas, convert the published start time from Japan time to your local time. If you are going in person, check the venue listed for that particular date. Once you pay attention to the ballpark column as well as the matchup, the schedule starts to tell you where baseball is taking place across Japan.
See what the interleague schedule adds
Under the 2026 format, each club played eighteen interleague games, three against each of the six teams from the other league. Your club and the rival closest to it in the standings may spend the same three days playing different opponents. A win can feel decisive as you watch the last out and still leave the standings exactly as they were. Looking across the week’s matchups explains how the results fit together.
Move between the standings and the game
A one-run win and a blowout each add one win to the standings. They can leave a club in different positions for the next day. In one game the starter might work deep. In another, the manager might use several relievers. During a series, see who is available to pitch after appearing the previous night and whether a pinch hitter who came through gets a start. The box score begins to explain decisions that the standings alone cannot show.
Keep a one-line scorebook
Write down the opponent, the park, and one play you want to remember. It could be a seventh-inning pitching change or a throw that beat a runner to second. When the same clubs meet again, look at the note. The venue and starting pitchers may be different, but you have a detail that connects the two games. Following a team over a season is partly the pleasure of starting to recognize those connections.
Watch one game from each league
If you have not picked a club, try a Central League game and a Pacific League game. The first turn through the order gives you something to follow even when the players are unfamiliar. What does each starter use to get ahead? Which pitches are the hitters willing to take? When those players face each other again, see what either side does differently. Across two broadcasts, you will also hear different crowds and see different views of the field. That comparison can tell you as much about what you want to watch as a list of clubs can.
Reconstruct a game from the official record
After the final out, use NPB’s scores to check when the runs came in and who appeared. If the game seemed to turn in the sixth, go back one batter or one pitching change before the run scored. You might have joined the broadcast late and missed how the first runner reached. The record gives you a place to begin.
Sometimes the record confirms what stood out at the park. Sometimes it sends you to an earlier moment. A pinch runner may have entered before the plate appearance that got the loudest cheer. If you have a replay, see how the defense reacted when that runner took a lead. Moving between the standings, the official record, and the game itself helps you see what went into a single win on a long schedule.
Check whether the schedule is for the first team or the farm team
NPB publishes separate schedules for first-team and farm competition. If a search for the club’s name turns up a fixture, read the schedule heading and check the opponent before adding it to your calendar. The uniform may carry the same organization’s name, but only a first-team league game goes into the first-team standings. When you are following a player, the two schedules give you separate places to look. A player missing from a first-team game may be worth looking up in the farm results for that day.
