Japan Rugby League One has backtracked on new contentious player registration rules that would classify some players as foreigners, even if they hold Japanese passports, limiting their domestic playing opportunities.  

This prompted legal challenges and a fierce backlash from players and fans, forcing the league to change course as the uproar threatened to become a prolonged dispute.

“The criticism was much stronger than we expected. We underestimated the reaction,” a League One executive said.

The top-tier rugby union tournament announced Aug. 28 that foreign-born players who had acquired Japanese citizenship, or applied for it, by May 2025 will be treated the same as Japanese-born players under the new system.

The rules are due to take effect in the 2026-27 season, which begins in December.

Facing mounting opposition, the league granted the exception for naturalized players rather than risk a prolonged dispute that could further damage the league’s image.

The move settles a dispute with players who argued that the original system was unfair and discriminatory because naturalized players would have been placed in a separate category from Japanese-born players.

Managing Executive Director Hajime Shoji acknowledged shortcomings in the league’s handling of the issue.

“We lacked communication with players who would be adversely affected by the changes. We would like to reflect on that,” he said.

The new system is intended to increase opportunities for Japanese-developed players by creating a category for those who spent at least six years of their compulsory education in Japan.

That will reduce the number of places available to foreign-born players eligible to represent Japan.

Under the original proposal, foreign-born players would have remained outside the Japanese-player category even after acquiring Japanese citizenship.

WORLD CUP HEROES

At the heart of the dispute was whether naturalized players should be treated differently from other Japanese players.

In April, 27 players filed a complaint with the Japan Fair Trade Commission, arguing that the new system constituted an “unfair trade practice” under Japan’s Antimonopoly Law.

Some also sought an injunction at the Tokyo District Court to block its implementation.

The group included naturalized Japanese internationals who helped the Brave Blossoms reach the Rugby World Cup quarterfinals for the first time in 2019.

Among them was star player Timothy Lafaele, who said at a widely covered news conference in July that he felt “saddened” by the policy despite having devoted himself to Japanese rugby.

The compromise represented a sharp turnaround from the stance League One had maintained for months.

TEAMS OVER PLAYERS?

At an April news conference, Chairman Genichi Tamatsuka defended the original rules, arguing that exceptions could create competitive imbalances because eligible players were unevenly distributed among teams.

“Ultimately, the league is built around its teams. We have no choice but to take steps to prevent unfairness between them,” he said.

The league applied the same reasoning to an exception allowing foreign-born players with at least 30 appearances for the Japanese national team to be treated as Japanese players.

Tamatsuka repeatedly argued that lowering the threshold would increase disparities among teams.

League One has maintained that the system was not intended to discriminate.

Even so, the controversy exposed what critics saw as a tendency to prioritize the interests of the league and its teams over players directly affected by the rules.

Sustained criticism from players and fans, coupled with legal action, ultimately forced the league to make concessions.
