Japan Rugby League One (Japanese: ジャパンラグビーリーグワン, romanized: Japanragubīrīguwan), formerly known as the Top League (Japanese: トップリーグ, romanized: Toppurīgu), is a rugby union competition in Japan. It is the highest level of industrial-professional rugby competition in the country. The Japan Rugby Football Union created the competition in 2003, by absorbing the Japan Company Rugby Football Championship. The chief architect of the league was Hiroaki Shukuzawa who strongly felt the urgency of improving Japanese domestic company rugby to a professional level which would allow Japan to compete more convincingly at Rugby World Cups.
It is an industrial league, where many players are employees of the corporations owning the franchise. While the competition was known for paying high salaries, only the world-class foreign players and a small number of Japanese players played fully professionally. The delayed 2021 season was the final season of the Top League, with the JRFU adopting a new fully-professional three-tier system from 2022.[1] More details about the new structure was announced to the media in January 2021. Featuring 25 teams, the 12 top-tier clubs would be split into two conferences, with seven teams competing in division two and six in division three.[2] The new competition was formally announced as Japan Rugby League One in July 2021.[3] Despite this measure, the competition still remains as a mixture of professional and employee players and has not yet transitioned to a fully professional competition.
The first season in 2003–04 featured 12 teams. The league was expanded to 14 teams in 2006–07 and 16 teams in 2013–14. While Japan Rugby League One's season[4] overlaps with the start of Super Rugby's season,[5] the Top League played during the off-season of the Super Rugby. Therefore, many full-time foreign professionals from Southern Hemisphere countries played in the Top League, notably Tony Brown, George Gregan and Dan Carter. In the 2010s, salaries in the Top League rose to become some of the highest in the rugby world[citation needed]; in 2012, South Africa's Jaque Fourie, now with Kobelco Steelers, was widely reported to be the world's highest-paid player.[6]
Teams
[edit]Since 2022, the Japan Rugby League One (JRLO) had three divisions with Division 1 being the top-flight division and holding the most teams.

Related competitions
[edit]A second-tier Top League Challenge Series was also introduced in 2003. Between 2003–04 and 2016–17, teams from three regional leagues would qualify to this post-season competition, in which they could either win promotion to the next season's Top League, or qualify to promotion play-off matches.
In 2017, a second-tier Top Challenge League was introduced, to operate in a league format above the regional leagues.[9]
The regional leagues are:
- Top East League, administered by the Japan East Rugby Football Union
- Top West League, administered by the Kansai Rugby Football Union
- Top Kyūshū League, administered by the Kyūshū Rugby Football Union
With the creation of Rugby League One and its three divisions, the raison d'etre for the Top Challenge League ceased to exist, and it was discontinued.
In 2025 it was announced that Japan Rugby League One would receive one berth in the inaugural 2028 Rugby Club World Cup organised by European Professional Club Rugby (EPCR), along with eight sides from EPCR and seven from Super Rugby Pacific.

Foreign players
[edit]The Japan Rugby Top League (JRTL) defined a "foreign player" as players holding foreign nationality (non-Japanese) who have a record of representing a national team other than Japan, with no possibility of becoming a Japanese representative.[11]
Between the competitions inaugural season in 2003 until the 2007–08 season, a limit of five foreign players were allowed in any matchday 23 squad, with two foreign players being the limit on the field at any one time per team.[12] This limit was increased to three beginning in 2008–09,[13] with the third foreign player designation being be a former Japanese national team player,[13] a player who is already eligible to be selected for the Japanese national team (meeting conditions such as residing in Japan for three years),[13] or a player who has not represented any other country (but who may become eligible to represent Japan in the future).[13] Although the second criterion was not applicable until the 2009–10 season.[13]
In late 2009, the Top League implemented specific player regulations ahead of the 2009–10 season regarding foreign and special category quotas.[14] Under the new rules, a maximum of three foreign players were allowed on the field simultaneously. At least one of these concurrently fielding players must fulfill the "Foreign National Special Quota Player" (Special Quota Player) requirement, which included having represented Japan, being eligible for selection for the Japanese national team, or having the potential to represent Japan in the future without prior representation for another country.[14] Special category players must've completed their registration with the JRTL by the end of June, and their eligibility remained valid for the duration of the season even if they lost their qualifying status midway through.[14] This was reverted back to two foreign players ahead of the 2012–13 season.[15]
In late 2021, before the start of the inaugural Japan Rugby League One season, a new player-quota system was implemented.[12] The regulations established three categories of players based primarily on nationality, international eligibility, and residency status. These were defined as:[16]
- Category A: Japanese international players who have not represented another national team, and foreign-born players who have completed the required five-year residency period and are therefore eligible to represent Japan.
- Category B: foreign players who may become eligible to represent the Japan national team in the future.
- Category C: foreign players who remain eligible only for their respective national teams.
Beginning in January 2022, League One clubs were required to have at least 11 Category A players on the field at any given time, with a minimum of 17 Category A players included on the official match sheet. Unlike Category A players, Category B players were not subject to a specific on-field limit.[16] Clubs were also permitted to field up to three Category C players, representing an increase from the two foreign internationals permitted under the previous Top League regulations. A further squad restriction was scheduled to take effect in January 2023, establishing a formal domestic-player quota for club squads.[16] Under the new system, Category A players were required to constitute at least 80 percent of a club's registered squad. Assuming a 50-player squad, this meant that at least 40 players had to belong to Category A. Category B and Category C players combined were consequently limited to no more than 20 percent of a squad, or a maximum of 10 players.[16]
The regulations also had implications beyond Japan. Foreign players from other Asian countries, including South Korea, Malaysia, the Philippines and Taiwan, had previously benefited from Japan's relatively open professional rugby environment.[16] Under the new classification system, players from these countries who did not qualify for Category A could instead be treated as Category B or Category C players, subjecting them to the same overall foreign-player limits as players from outside Asia. This raised concerns about the potential loss of opportunities for Asian players within Japan's professional rugby system.[16]
2026–27 policy change and dispute
[edit]In 2025, reports emerged that the foreign player quota would undergo another change to begin in the 2026–27 season.[17][18] Under the revised system, Category A would be divided into A1 and A2. Category A1 would cover players with Japanese birth or ancestry, specified Japanese schooling, or at least 30 caps for Japan. Category A2 would include players registered exclusively with the Japan Rugby Football Union (JRFU) for four consecutive years.[18] Japan internationals with fewer than 30 caps would initially be classified as A2 but could move to A1 after reaching the 30-cap threshold. A2 players would count toward clubs' foreign-player quotas, while their classification would not affect their eligibility to represent Japan under World Rugby rules.[18] Under these proposed reforms, clubs from the 2026–27 season onward would have to field at least eight A1 players, replacing the prior requirement of 11 Category A players.[18]
With these new changes set to commence ahead of the season, twenty-four players launched legal action, filing a complaint with Japan's Fair Trade Commission (FTC) and seeking an injunction in the Tokyo District Court to stop the rules from taking effect, claiming claiming the policy was discriminatory against foreign-born players, including naturalised Japanese citizens who have represented Japan internationally.[19] In August 2026, the Japan Rugby League One reached a settlement concerning the eligibility of Japanese players born overseas, revising the initially planned regulations. Players who had acquired Japanese nationality by the end of May 2025 were subsequently treated on the same basis as Japanese-born players.[20] Among those affected was Timothy Lafaele, a prominent member of Japan's 2019 Rugby World Cup squad.[20]
The foreign player quota beginning in the 2026–27 season, were:[21]
- Category A-1: Players without international representative history for another union who either spent at least six years of compulsory education in Japan, have familial/birth ties to Japan, qualify under Article 11 (Paragraph 1, Item 4, sub-items a–d) of the current Player Contract and Registration Regulations, or were registered as Category A up to the 2025–26 season and acquired (or applied for and subsequently acquired) Japanese nationality on or before 31 May 2025 (14 or more eligible in the matchday squad, eight or more allowed on the pitch at any one time).
- Category A-2: Players other than the above who have no international representative history for another union and have been continuously registered with the JRFU for 48 months or more.
- Category B: Players other than the above who have no international representative history for another union and have not yet completed continuous registration with the JRFU for 48 months or more (nine or less eligible in the matchday squad, six or less in nine allowed on the pitch at any one time).
- Category C: Players who have represented another union (three or less in six eligible in the matchday squad, three or less in seven allowed on the pitch at any one time).
Asian quota
[edit]Since 2003 there has been one slot per team for a non-Japanese Asian player (defined as a player holding citizenship within the Asian region) that would be exempt from the foreign player quota.[14] In 2021, following changes to the JRLO regulations, this policy was scrapped although the quota would still apply to Asian players who were registered on or before the 2021 season.
