Nippon Professional Baseball (日本野球機構, Nippon Yakyū Kikō) or NPB is the highest level of baseball in Japan. Locally, it is often called Puro Yakyū (プロ野球), meaning Professional Baseball.

Outside Japan, it is often just referred to as "Japanese baseball". The roots of the league can be traced back to the formation of the "Greater Japan Tokyo Baseball Club" (大日本東京野球倶楽部, Dai-Nippon Tōkyō Yakyū Kurabu) in Tokyo, founded in 1934, and the original circuit for the sport in the Empire two years later – Japanese Baseball League (1936–1949), and continued to play even through the final years of World War II.The league that is today's NPB for Japan was formed when that sports organization reorganized in 1950, creating two leagues with six teams each in the Central League and the Pacific League with an annual season-ending Japan Series championship play-off series of games starting that year.

League structure

Nippon Professional Baseball consists of two leagues, the Central League and the Pacific League, which each have six teams. There are also two secondary-level professional minor leagues, the Eastern League and the Western League, that play shorter schedules for developing players.

The season starts in late March or early April, and ends in October, with two or three all-star games in July. In recent decades prior to 2007, the two leagues each scheduled between 130 and 140 regular season games, with the 146 games played by the Central League in 2005 and 2006 being the only exception. Both leagues have since adopted 146-game seasons, 73 each at home & on road. In general, Japanese teams play six games a week, with every Monday off.[1]

Following the conclusion of each regular season the best teams from each league go on to play in the "Nippon Series" or Japan Series championship play-off tournament.

In 2004, the Pacific League played five fewer games than the Central League teams during the regular season and used a new playoff format to determine its champion (and which team would advance to the Japan Series). The teams in third and second place played in a best-of-three series (all at the second place team's home ground) with the winner of that series going on to play the first place team in a best-of-five format at its home ground. In 2007, the Central League adopted the Pacific League's tournament as well, and the tournament became known as the Climax Series with the two winners, one from each league, competing in the Japan Series.[citation needed]

Financial problems

Financial problems plague many teams in the league. It is believed that with the exception of the Yomiuri Giants and the Hanshin Tigers, all teams are operating with considerable subsidies, often as much as ¥6 billion (about US$73 million), from their parent companies. A raise in the salaries of players is often blamed, but, from the start of the professional league, parent companies paid the difference as an advertisement. Most teams have never tried to improve their finances through constructive marketing. In addition, teams in the Central League historically saw much higher profits than the Pacific League, having popular teams such as the Giants and Tigers.[2]

The number of metropolitan areas represented in the league increased from four to five in 1988, when the Nankai Hawks (now Fukuoka SoftBank Hawks) moved to Fukuoka; and to seven between 2003 and 2005, as the Nippon-Ham Fighters moved to Hokkaidō and the Osaka Kintetsu Buffaloes merged with the Orix BlueWave (becoming the Orix Buffaloes) and were replaced by the Tohoku Rakuten Golden Eagles.[citation needed]

Until 1993, baseball was the only team sport played professionally in Japan. In that year, the J.League professional football league was founded. The new football league placed teams in prefectural capitals around the country—rather than clustering them in and around Tokyo—and the teams were named after their locations rather than after corporate sponsors.

The wave of players moving to Major League Baseball, which began with Hideo Nomo "retiring" from the Kintetsu Buffaloes, then signing with the Los Angeles Dodgers, has also added to the financial problems. Attendance suffered as teams lost their most marketable players, while TV ratings declined as viewers tuned into broadcasts of Major League games.[3] To discourage players from leaving to play in North America, or to at least compensate teams that lose players, Japanese baseball and MLB agreed on a posting system for players under contract. MLB teams wishing to negotiate with a player submit bids for a "posting fee", which the winning MLB team would pay the Japanese team if the player signs with the MLB team. Free agents are not subject to the posting system, however.[4]



The first professional baseball team in Japan was founded by media mogul Matsutarō Shōriki in late 1934 and called the Dai Nippon Tokyo Yakyu Kurabu ("the Great Japan Tokyo Baseball Club"). After matching up with a team of visiting American All-Stars that included Babe Ruth, Jimmie Foxx, Lou Gehrig, and Charlie Gehringer, the team spent the 1935 season barnstorming in the U.S., winning 93 of 102 games against semi-pro and Pacific Coast League teams. According to historian Joseph Reaves, "The only minor drawbacks to the team's popularity in the States were their kanji characters and their cumbersome Japanese name. They rectified both by renaming themselves the Tokyo Kyojin ['Tokyo Giants'] and adopting a uniform identical to the New York Giants…"[5]

From 1936 to 1950, professional baseball in Japan was played under the banner of the Japanese Baseball League (JBL). The league's dominant team during this period was the Tokyo Kyojin, which won nine league championships, including six in a row from 1938 to 1943. (The team was officially renamed the Yomiuri Giants in 1947.)

NPB establishment

After the 1949 season, the JBL team owners reorganized into the NPB; Daiei Stars owner Masaichi Nagata promoted a two-league system, which became the Pacific League (initially called the Taiheiyo Baseball Union) and the Central League. (Nagata became the first president of the Pacific League.)[6] The league now known as Nippon Pro Baseball began play in the 1950 season.

Four JBL teams formed the basis of the Central League: the Chunichi Dragons, the Hanshin Tigers, the Yomiuri Giants, and the Shochiku Robins (formerly the Taiyō Robins). To fill out the league, four new teams were formed: the Hiroshima Carp, the Kokutetsu Swallows, the Nishi Nippon Pirates, and the Taiyō Whales.

Four JBL teams formed the basis of the Pacific League: the Hankyu Braves, the Nankai Hawks, the Daiei Stars, and the Tokyu Flyers. To fill out the league, three new teams were formed: the Kintetsu Pearls, the Mainichi Orions, and the Nishitetsu Clippers.

Matsutarō Shōriki, the Giants' owner, acted as NPB's unofficial commissioner and oversaw the first Japan Series, which featured the Mainichi Orions defeating the Shochiku Robins 4 games to 2.

Expansion and contraction

The Central League's Nishi Nippon Pirates existed for one season — they placed sixth in 1950, and the following season merged with the Nishitetsu Clippers (also based in Fukuoka) to form the Nishitetsu Lions. This brought the number of Central League teams down to an ungainly arrangement of seven. In 1952, it was decided that any Central League team ending the season with a winning percentage below .300 would be disbanded or merged with other teams. The Shochiku Robins fell into this category, and were merged with the Taiyō Whales to become the Taiyō Shochiku Robins in January 1953. This enabled the Central League to shrink to an even number of six teams.

In 1954 a new Pacific League team was founded, the Takahashi Unions, to increase the number of teams in that division to eight. Although the team was stocked with players from the other Pacific League teams, the Unions struggled from the outset and finished in the second division every season. In 1957, the Unions were merged with the Daiei Stars to form the Daiei Unions (and again bringing the number of Pacific League teams down to seven). The Unions existed for a single season, finishing in last place, 43-1/2 games out of first. In 1958, the Unions merged with the Mainichi Orions to form the Daimai Orions. This enabled the Pacific League to contract from the ungainly seven-team arrangement to six teams.

After these various franchise developments, by the end of the 1950s Nippon Professional Baseball had contracted from the initial allotment of 15 teams down to the current number of 12.

1960s and 1970s

On September 1, 1964, Nankai Hawks' prospect Masanori Murakami became the first Japanese player to play in Major League Baseball[7] when he appeared on the mound for the San Francisco Giants; he returned to Japan in 1966. Disputes over the rights to his contract eventually led to the 1967 United States – Japanese Player Contract Agreement; it would be almost 30 years before another Japanese player played in the Major Leagues.

Continuing their dominance from the JBL, the Yomiuri Giants won nine consecutive Japan Series championships from 1965 to 1973.

The Black Mist Scandal rocked Nippon Professional Baseball between 1969 and 1971. The fallout from a series of game-fixing scandals resulted in several star players receiving long suspensions, salary cuts, or being banned from professional play entirely; the resulting abandonment of baseball by many fans in Japan also led to the sale of the Nishitetsu Lions and the Toei Flyers.

From 1973 to 1982, in a forerunner to today's Climax Series playoff rounds, the Pacific League employed a split season with the first-half winner playing against the second-half winner in a mini-playoff to determine its champion. In 1975, the Pacific League adopted the designated hitter rule.

1980s and the "Invincible Seibu"

After being a second division team for much of the 1960s and 1970s, in 1983 the Seibu Lions began a period of sustained success. The team gained the moniker "Invincible Seibu" during the 1980s and 1990s due to their sustained domination of the league, winning 11 league championships and eight Japan Series championships between 1982 and 1994. The Lions had a powerful lineup in this period, loaded with sluggers such as Koji Akiyama, Kazuhiro Kiyohara, and Orestes Destrade. Their defense also benefited from the services of skilled players such as Hiromichi Ishige, Hatsuhiko Tsuji and catcher Tsutomu Ito. Among the pitchers employed by the Lions in this period was "The Oriental Express" Taigen Kaku, Osamu Higashio, Kimiyasu Kudoh, Hisanobu Watanabe, and relievers Yoshitaka Katori and Tetsuya Shiozaki.

American expatriate players made their mark in NPB in the 1980s, with players like the Lee brothers (Leron Lee and Leon Lee), Greg "Boomer" Wells, Randy Bass, and Ralph Bryant playing key roles on their NPB teams.

Hideo Nomo and the exodus to MLB

In 1995, star pitcher Hideo Nomo "retired" from the Kintetsu Buffaloes and signed with the Los Angeles Dodgers. Nomo pitched over the span of 14 seasons in the Major Leagues before retiring in 2008. He won the Rookie of the Year Award in 1995. He twice led the league in strikeouts, and also threw two no-hitters (the only Japanese pitcher to throw a no-hitter in Major League Baseball until Hisashi Iwakuma achieved the feat in August 2015). Nomo's MLB success led to more NPB players moving to Major League Baseball,[8] and eventually led to the creation of the "posting system" in 1998.[9]

Since Nomo's exodus, more than 60 NPB players have played Major League Baseball. Some of the more notable examples include:

Merger and strike of 2004

Main article: 2004 Nippon Professional Baseball realignment

In September 2004, the professional Japanese players went on strike for the first time in over 70 years. The strike arose from a dispute that took place between the owners of the 12 professional Japanese baseball teams and the players' union (which was led by popular Yakult Swallows player-manager Atsuya Furuta), concerning the merging of the Osaka Kintetsu Buffaloes and the Orix BlueWave. The owners wanted to get rid of the financially defunct Buffaloes, and merge the two baseball leagues, since teams in the Central League saw much higher profits than the Pacific League, having popular teams such as the Yomiuri Giants and Hanshin Tigers. After negotiations, the owners agreed to guarantee the survival of the Chiba Lotte Marines and the Fukuoka Daiei Hawks, leaving the Central League with six teams and the Pacific League with five.[citation needed]

A battle escalated between the players union and the owners, and reached its height when Yomiuri Giants owner Tsuneo Watanabe controversially remarked that Furuta was "a mere player,"[15] implying that players had no say in what league would look like the next year. The dispute received huge press coverage (which mostly favored Furuta and the players' union) and was dubbed one of the biggest events in the history of Japanese baseball. Proposals and amendments concerning interleague games, player drafting, and management were also discussed between the players union and the owners during this period.

The strike was originally planned for all Saturday and Sunday games that month, starting from September 11, but was pushed back due to the agreement of another meeting between the union and the owners on September 10. The players decided to strike on September 18–19, 2004, when no progress was made in the negotiations, as there was insufficient time left in the season to hold discussions.[citation needed]

The dispute officially ended after the two groups reached consensus on September 23, 2004. As part of the agreement, the Buffaloes were allowed to merge with the Blue Wave (forming into the Orix Buffaloes); in addition, the Rakuten Golden Eagles were newly created (at a reduced "entry fee") to keep the former six-team league structure. Other agreements included the leagues adopting interleague play to help the Pacific League gain exposure by playing the more popular Central league teams. All these changes took place before the 2005 season.

Interleague play

Main article: Interleague play (NPB)

The two leagues began interleague play in 2005, with each team playing two three-game series (one home, one away) against each of the six teams in the other league. This was reduced to two two-game series in 2007. All interleague play games are played in a seven-week span near the middle of the season.

As of the end of the 2017 season, the Pacific League has won the most games in interleague play since it began in 2005 twelve times, with 2009 being the only time that the Central League has won more games.

League championship series/Climax Series

Main article: Climax Series

After 2004, a three-team playoff system was introduced in the Pacific League, dubbed the "Pacific League Championship Series." The teams with the second- and third-best records play in the three-game first stage, with the winner advancing to the five-game final against the top team. The winner becomes the representative of the Pacific League to the Japan Series.

Since the Pacific League won every Japan Series after introducing this league playoff system, an identical system was introduced to the Central League in 2007, and the post-season intra-league games were renamed the "Climax Series" in both leagues. Player statistics and drafting order based on team records are not affected by these postseason games.

Recent history

In 2011 Miyagi Baseball Stadium, home of the Rakuten Eagles, was badly damaged by the Tōhoku earthquake and tsunami.[16]

The 2013 season featured a livelier baseball which was secretly introduced into NPB, resulting in a marked increase in home runs league-wide.[17] Tokyo Yakult Swallows outfielder Wladimir Balentien broke the NPB single-season home run record of 55, previously held by professional baseball's all-time home run leader Sadaharu Oh in 1964, Tuffy Rhodes in 2001, and Alex Cabrera in 2002.[18] Balantien finished the season with 60 home runs. Three-term NPB commissioner Ryōzō Katō was forced to resign over the scandal when the changed baseball was revealed.[17]

Former Prime Minister Shinzō Abe's ruling Liberal Democratic Party has proposed expanding NPB to 16 total teams by adding two expansion franchises in each of the country's top-tier professional baseball leagues. The goal of such a move would be to energize the economies of the regions receiving the new teams. Okinawa, Shizuoka, Shikoku, and Niigata have been identified as regions that could play host to said teams.[19]

The 2020 NPB season was delayed numerous times due to the COVID-19 pandemic. Initially preseason games were set to be played without spectators, but with opening day of March 20 remaining unchanged.[20] With the lifting of states of emergency over major Japanese cities, NPB announced that it would begin its regular season on 19 June behind closed doors. "Warm-up" games began 26 May.[21] The shortened 120-game regular season began on 19 June.[22] On 10 July NPB began allowing a limited number of fans to attend games, with plans to further ease restrictions in the near future.[23] On 19 September, attendance was expanded to a maximum of 20,000 fans per game, or 50% of stadium capacity.[24]

Expatriate baseball players in Japan

Main article: American expatriate baseball players in Japan

For most of its history, NPB regulations imposed "gaijin waku", a limit on the number of non-Japanese people per team to two or three — including the manager and/or coaching staff.[25] Even today, a team cannot have more than four foreign players on a 25-man game roster, although there is no limit on the number of foreign players that it may sign. If there are four, they cannot all be pitchers nor all be position players.[25] This limits the cost and competition for expensive players of other nationalities, and is similar to rules in many European sports leagues' roster limits on non-European players.

Nonetheless, expatriate baseball players in Japan have been a feature of the Japanese professional leagues since 1934. Hundreds of foreigners — particularly Americans — have played NPB. Taiwanese nationals Shosei Go and Hiroshi Oshita both starred in the 1940s. American players began to steadily find spots on NPB rosters in the 1960s. American players hold several NPB records, including highest career batting average (Leron Lee, .334), highest single-season batting average (Randy Bass, .389), and the dubious record of most strikeouts in a season by a hitter (Ralph Bryant, 204). Americans rank #3 (Tuffy Rhodes, 55) and #5 (Randy Bass, 54) on the list of most home runs in a season, and #2 in single-season RBI (Bobby Rose, 153). CuraçaoanDutch outfielder Wladimir Balentien holds the NPB single-season home run record with 60 round-trippers in 2013.

Koreans have had an impact in the NPB as well, including such standout players as Lee Seung-yuop, Sun Dong-yol, Baek In-chun, Lee Jong-beom, and Dae-ho Lee. Venezuelans Alex Ramírez, Alex Cabrera, Bobby Marcano, and Roberto Petagine all had long, successful NPB careers. The Dominican third-baseman José Fernández played eleven years in the NPB, compiling a .282 batting average with 206 home runs and 772 runs batted in.

Many of the most celebrated foreign players came to Japan after not finding success in the Major Leagues; see "Big in Japan".

Since the 1970s, foreigners have also made an impact in Nippon Professional Baseball's managing and coaching ranks, with Americans Bobby Valentine and Trey Hillman managing their respective teams to Japan Series championships.
