The 2025–26 Japan Rugby League One – Division 1 (Japanese: NTTジャパンラグビー リーグワン2025–26), known as the NTT 2025–26 Japan Rugby League One for sponsorship reasons, will be the fifth season of the Japan Rugby League One and the 22nd season in top-flight Japanese rugby. The season begins in December 2025 and ends in June 2026 with teams placed in the Play-offs and Relegation play-offs rounding out the season.[1] The teams remained unchanged from the previous season (2024–25) as both teams in the relegation zone (Honda Heat, Urayasu D-Rocks) defeated the top two Division 2 teams over two-legs.[2][3]

Format

The format will consist of a round-robin fixture, before entering into a knockout style play-off for the final four teams. It featured two conferences (A, B).[1] Teams in each conference played the teams in their respective conference twice (one at home, one away), and six matches against all the teams in the other conference, three being at home and three away.[1] Each team played a total of sixteen seasonal fixtures, plus additional play-off matches, including relegation play-offs.[1]

Teams, venues and personnel

Venues and stadia

The competition fixture list and venues for the season were announced on 31 July 2025.[4] Despite no 2025–26 Division 1 team being located on the island and prefecture of Hokkaido,[4] the Toshiba Brave Lupus hosted the Urayasu D-Rocks in Round 14 of the season at the Sapporo Dome in Hokkaido.[5] Similarly, no 2025–26 Division 1 team is located on the Southern Island of Kyushu, however Tokyo Sungoliath, the Sagamihara DynaBoars, Toyota Verblitz, and the Yokohama Canon Eagles all host one or two fixtures at various venues on the island throughout the season.

International players

The Japan Rugby League One divides players into three category's based on their international eligibility to the Japan national team (Category A, Category B, Category C). Under "Category A", at least 17 members of a matchday squad must be Japan-qualified which includes foreign-born players who qualify based on residency grounds.[6] "Category B" is marked to internationally uncapped players who could potentially qualify for Japan in the future.[6] And "Category C" allows three internationally test-capped players to be in the matchday squad.[6][7] Overall, a combined total of six "Category B" and "Category C" players can be named in a matchday squad.[6]

The Japan Rugby League One's "Category C" player quota for 2025–26 is:[8]
