This will mark the first time that the League of Legends World Championship will be hosted in Japan.
League of Legends (LoL) developer Riot Games has announced that the game's 2027 world championship tournament, more commonly known as Worlds, will be hosted in Japan and South Korea.
Aside from announcing the host countries for next year's Worlds, Riot also revealed the host countries for the scene's other major international events, namely the First Stand tournament and the Mid-Season Invitational (MSI).
Riot notably revealed its roadmap for LoL esports' 2027 season ahead of the grand finals of Worlds 2026, which will see 
Gen.G and 
Bilibili Gaming clash for the right to raise this year's Summoner's Cup on Sunday (15 November).
Japan and South Korea to host Worlds 2027
After initially announcing that South Korea will be hosting Worlds 2027, Riot has expanded the scale of the tournament and revealed that Japan will also be hosting a part of the event. The Worlds 2027 Swiss Stage will now be hosted in Nagoya, Japan though a specific venue has yet to be revealed. This notably marks the first time that Japan has hosted the LoL world championship.
“Japan has a passionate and growing League of Legends community, and we're excited to give Japanese fans the opportunity to experience the world's biggest League of Legends competition in person,” Riot said of their decision to partly host Worlds 2027 in Japan.
The Worlds 2027 Knockout Stage will then be hosted in South Korea, with the quarterfinals and semifinals taking place in the Suwon Convention Center in Suwon while the grand finals will be held in the Seoul Arena in Seoul.
In addition, Riot revealed that they are exploring plans to replace the Worlds Play-In Stage with the Demacia Cup. These plans are aimed at “potentially creating more best-of series and opportunities for teams to compete for a place at Worlds,” though no decisions have been finalised yet.
First Stand: All In announced, venue moved from Southeast Asia to China
While Worlds 2027 will serve as the culmination of the 2027 LoL esports season, Riot also revealed another change to the competitive calendar aimed at its opening international event. The First Stand tournament is getting a major expansion in 2027 with First Stand: All In, a one-time event that will feature more teams and, according to Riot, “will be the largest tournament we've ever produced.”
“This special edition of First Stand is designed to stand apart in 2027, bringing even more competition at the highest level to the start of the season,” added Riot.
As part of these plans, Riot have moved First Stand 2027 from its previously announced venue in Southeast Asia to China. The developer assured that they remain committed to bringing major international competitions to Southeast Asia and confirmed that First Stand will be hosted in the region in 2028.
Spain to host MSI for the first time
Finally, Riot announced that MSI 2027 will be hosted in the Feria de Valencia in Valencia, Spain. This will mark the first time that Spain will host LoL's premier mid-season international competition.
“With its rich sporting culture and passionate League of Legends community, Valencia will provide an exciting new backdrop for one of our biggest international competitions,” said Riot.
