The League of Legends Japan League (LJL) is the top level of professional League of Legends competition in Japan. The league franchised prior to start of the 2019 season and had eight teams under partnership (which became six in 2024).
Before 2024, the spring and summer champions qualified for the Mid-Season Invitational and World Championship respectively. However, in 2024, the top three teams from each LJL split were seeded into the Pacific Championship Series (PCS) playoffs and competed with other PCS teams for a chance to represent the larger region at international events; LJL teams would no longer qualify directly to MSI and Worlds. Since 2025, the LJL is a second division to the League of Legends Championship Pacific (LCP).
Each annual season of play is divided into three splits, Forge, Storm and Ignite, which then conclude a with playoff tournament known as the LJL Finals. The winner of the LJL Finals qualifies for the LCP Promotion Tournament for the opportunity to qualify for the Asia-Pacific tier one league.
