Before the professional league (pre-1992)

Before the inception of the J.League, the highest level of club football was the Japan Soccer League (JSL), which consisted of amateur clubs.^[1][2] Despite being well-attended during the boom of the late 1960s and early 1970s (when Japan's national team won the Olympic bronze medal at the 1968 games in Mexico), the JSL went into decline in the 1980s, in general line with the deteriorating situation worldwide. Fans were few, the grounds were not of the highest quality, and the Japan national team was not on a par with the other Asian powerhouses. To raise the level of play domestically, to attempt to garner more fans, and to strengthen the national team, the Japan Football Association (JFA) decided to form a professional league. During this era, Japanese football investors traveled exclusively to Europe to find a possible model; eventually, the Japanese embraced the model of Germany's Bundesliga to develop its own professional league.^[3]

The professional association football league, J.League was formed in 1992, with eight clubs drawn from the JSL First Division, one from the Second Division, and the newly formed Shimizu S-Pulse. At the same time, JSL changed its name to Japan Football League, becoming a semi-professional league. Although the J.League did not officially launch until 1993, the Yamazaki Nabisco Cup competition was held between the ten clubs in 1992 to prepare for the inaugural season.

Inaugural season and J.League boom (1993–1995)

J.League officially kicked off its first season with ten clubs on 15 May 1993, when Verdy Kawasaki hosted Yokohama Marinos at the Tokyo National Stadium.

After the boom (1996–1999)

Despite the success in the first three years, in early 1996 the league attendance declined rapidly, coincided with the economic slump of Japan. In 1997, the average attendance was 10,131, compared to more than 19,000 in 1994. Yokohama Flügels were merged with Yokohama Marinos due to the withdrawal of one of their major sponsors, right after they became the winners of the 1998 Emperor's Cup on 1 January 1999.

Change of infrastructure and game formats (1999–2004)

The league's management realized that they were heading in the wrong direction. In order to solve the problem, the management came out with two solutions.

First, they announced the J.League Hundred Year Vision, in which they aim to make 100 professional association football clubs in the nation of Japan by 2092, which would be the hundredth season. The league also encouraged the clubs to promote football or non-football related sports and health activities, to acquire local sponsorships, and to build good relationships with their hometowns at the grass-root level. The league believed that this would allow the clubs to bond with their respective cities and towns and get support from local government, companies, and citizens. In other words, clubs would be able to rely on the locals, rather than major national sponsors.

Second, the infrastructure of the league was heavily changed in 1999. The league acquired nine clubs from the semi-professional JFL and one club from J. League to create a two-division system. The top flight became the J.League Division 1 (J1) with 16 clubs while J.League Division 2 (J2) was launched with ten clubs in 1999. The second-tier Japan Football League (former), now became third-tier Japan Football League.

Also, until 2004 (with the exception of 1996 season), the J1 season was divided into two. At the end of each full season, the champion from each half played a two-legged series to determine the overall season winner and runners-up. Júbilo Iwata in 2002, and Yokohama F. Marinos in 2003, won both "halves" of the respective seasons, thus eliminating the need for the playoff series. This was the part of the reason the league abolished the split-season system starting from 2005.

European League Format & AFC Champions League (2005–2008)

Since the 2005 season, J.League Division 1 consisted of 18 clubs (from 16 in 2004) and the season format became similar to the European club football. The number of relegated clubs also increased from 2 to 2.5, with the third-from-bottom club going into Promotion / relegation Series with the third-placed J2 club. Since then, other than minor adjustments, the top flight has stayed consistent.

Japanese teams did not treat the Asian Champions League that seriously in the early years, in part due to the distances travelled and teams played. However, in the 2008 Champions League, three Japanese sides made the quarter-finals.^[4]

However, in the recent years, with the inclusion of the A-League in Eastern Asia, the introduction of FIFA Club World Cup, and increased marketability in the Asian continent, both the league and the clubs paid more attention to Asian competition. For example, Kawasaki Frontale built up a notable fan base in Hong Kong, owing to their participation in the AFC Champions League during the 2007 season.^[5] Continuous effort led to the success of Urawa Red Diamonds in 2007 and Gamba Osaka in 2008. Thanks to excellent league management and competitiveness in Asian competition, the AFC awarded J.League the highest league ranking and a total of four slots starting from the 2009 season. The league took this as an opportunity to sell TV broadcasting rights to foreign countries, especially in Asia.

Also starting the 2008 season, Emperor's Cup Winner was allowed to participate in the upcoming Champions League season, rather than waiting a whole year (i.e. 2005 Emperor's Cup winner, Tokyo Verdy, participated in the 2007 ACL season, instead of the 2006 season). In order to fix this one-year lag issue, the 2007 Emperor's Cup winner, Kashima Antlers' turn was waived. Nonetheless, Kashima Antlers ended up participating in the 2009 ACL season by winning the J.League title in the 2008 season.

Modern phase (2009–2014)

Three major changes were seen starting in the 2009 season. First, starting that season, four clubs entered the AFC Champions League. Secondly, the number of relegation slots increased to three. Finally, the AFC Player slot was implemented starting this season. Each club will be allowed to have a total of four foreign players; however, one slot is reserved for a player that derives from an AFC country other than Japan. Also, as a requirement of being a member of the Asian Football Confederation, the J.League Club License regulations started in 2012 as one criterion of whether a club was allowed to stay in its division or to be promoted to a higher tier in the professional level league. No major changes happened to J.League Division 1 as the number of clubs stayed at 18.

Three-stage system (2015–present)

From 2015 the J.League system changed to a three-stage system. The year is split into first and second league stages, followed by a third and final championship stage. The third stage is composed of stage one and two's total point champions and up to four other teams. These additional four teams consist of the following: Stage one and stage two's top point accumulator, and stage one and two's second placed points accumulator. These five teams then take part in a championship playoff stage to decide the winner of the league trophy.

In 2017, the single-table format returned due to a negative reaction from hardcore fans and a failure to appeal to casual fans.^{[citation needed]}

Promotion and relegation between J3 and the JFL began in the 2023 season.^[6] The J.League will transition to a fall–spring calendar beginning in the 2026–27 season to align with Europe competitions and the Asian Champions League as well as avoid summer matches and conflicts with international tournaments. The change was approved on December 19, 2023, following a vote of the 60 J.League clubs.^[7]

About the future

The J.League has announced a policy of setting a maximum of 20 teams for the J3 League and 60 teams for the total number of regular member teams including J1 and J2. According to interviews with people involved in the J.League, it has become clear that J1, J2 and J3 are proposing to have 20 teams each from 2024 at the earliest.

In conjunction with the increase in the number of teams, this is a new growth strategy that revises the ratio of equal distribution money and in particular, the policy of grading allocation centered on the top clubs of J1. It is said that the aim is to improve the value of the J. League by increasing the provision of high quality matches. If there are 20 teams in each class, in 2023, only the lowest (18th) club will be demoted from J1 to J2 and conversely, 3 clubs will be promoted from J2 to J1. It is said that there is.

After that, on 20 December 2022, based on the J League's two new growth strategies ("60 clubs shine in their respective regions" and "top tier shines as national (global) content"), From the 2024 season, J1, J2 and J3 will have 20 teams each and J. League cup games will officially be renewed to a knockout (tournament) format in which all 60 clubs from J1, J2 and J3 will participate was announced in.
