The World Cosplay Summit (abbreviated as CosSami) is one of the world's largest cosplay events, having started in 2003 and celebrating its 24th edition this year.
This event brings together cosplayers and cosplay fans who love Japanese pop culture such as anime, manga, and games, creating a new form of international and cultural exchange.
Every year, more than 200,000 people visit, and cosplayers from all over the world gather in Nagoya City, Aichi Prefecture, to deepen their connections with one another.
One of its distinguishing features is the support it receives from local governments, administrative bodies, and overseas diplomatic missions. With each passing year, the number of participating countries and regions has increased, making it a cosplay event that attracts attention from all over the world.
This year, the World Cosplay Championship, a global competition to determine the best cosplay performer from around the world, will bring together a record-breaking 42 countries and regions (planned) in Nagoya, the mecca of cosplay, to showcase cosplay performances themed around Japanese works.
This tournament is an appealing event not only for cosplay fans but also for adults and children alike, especially now that Japanese pop culture is attracting attention from all over the world.
For unforgettable summer memories, please come to Nagoya and witness the performances of top cosplayers from around the world and regions. (Separate tickets are required to attend the World Cosplay Championship.)
