From corporate hobby to global stage: Japan's rugby evolution

Countries & Cities · Published 13 October 2026 Swipe more like this →

In short: Japan's top rugby league isn't just a domestic competition; it is a high-stakes laboratory for professionalizing a corporate sport. By blending industrial employee-athletes with world-class international stars, the league has transformed from a local championship into a global powerhouse with a seat at the world's biggest tables.

Founded in 2003 by Hiroaki Shukuzawa, Japan Rugby League One (formerly the Top League) was born from a sense of urgency. Shukuzawa aimed to elevate domestic 'company rugby' to a professional standard, specifically to help Japan compete more effectively in Rugby World Cups. This transition created a unique hybrid model: an industrial league where many players remain employees of the corporations that own the franchises, while also hosting elite international talent. The league was established by absorbing the Japan Company Rugby Football Championship. It originally launched with 12 teams in its first season. The competition also includes a second-tier system for regional teams to seek promotion.

The league's financial landscape has been notable for its ambition. Paycales within the Top League climbed throughout the 2010s, reaching global peaks. In 2012, South African player Jaque Fourie was widely reported as the world's highest-paid rugby player while competing for the Kobelco Steelers. To maintain high standards, the league has historically integrated top-tier foreign professionals from the Southern Hemisphere during their off-seasons, featuring icons like Dan Carter and George Gregan. The league introduced a timekeeping system independent of the referee in 2007–08. Video referee decisions were first used for a specific playoff tournament in 2008–09. By 2014–15, these video decisions were implemented for every single league match.

The structure has undergone significant modernization. In 2021, the league transitioned to a three-tier system, with the top flight featuring 12 clubs. While it still balances professional and employee status, the league is moving toward full professionalism. This trajectory has already paid off; in 2025, it was announced that the league would secure a berth in the inaugural 2028 Rugby Club World Cup, joining elite sides from Europe and Super Rugby Pacific. The league expanded to 16 teams during the 2013–14 season. It currently allows three foreign players on the field at once. One of these spots must be reserved for a player eligible to represent Japan.
