The 2015 Meiji Yasuda J1 League (2015 明治安田生命J1リーグ) season was the 50th season of top-flight football in Japan and the 23rd since the establishment of the J.League in 1992. This was first season of J1 League as renamed from J. League Division 1.
For a five-year period starting in 2015, the J.League changed to a newly conceived multistage system, with the year split into two halves and a third and final championship stage. The winners of the first and second stages and the highest ranking club of the aggregate table (other than the first or second stage winners) will qualify for the Championship Stage. Sanfrecce Hiroshima won the Championship Stage and advanced to the 2015 FIFA Club World Cup as the host nation's entrant.

Teams play a single round-robin in the first stage and a single round-robin in the second stage. After that an overall table is calculated and a championship stage is played. The winners of the first and second stages and any team that finishes in the top 3 of the overall rankings advance to the championship stage. The team that finishes atop the overall table automatically qualifies for the final, while the remaining teams play-off for the other spot in the final.
