Jump Festa (Japanese: ジャンプフェスタ, Hepburn: Janpu Fesuta) is an annual party or exposition in Japan, all about manga and anime, sponsored by Shueisha, publisher of the various Jump anthologies which are Weekly Shōnen Jump, Jump Square, V Jump, Saikyō Jump and Shōnen Jump+. The exposition was started in 1999, and is held for two days in December with over 100,000 people attending every year. New manga, anime, films, games, and merchandise are introduced during this event. Manga artists of popular current and former Jump series are often on hand, and many of them have panels where they answer questions. The festival's mascot is named Kaizo-kun (KAIZOくん) and was designed by Akira Toriyama.
