Jump Festa is an annual party or exposition in Japan, all about anime and manga, sponsored by Shueisha, creators of the various Jump anthologies. New movies, manga, games and merchandise are introduced during this event. The tradition is that of already existing material a special item or episode is produced and presented at the convention to prove the makers aren’t out of ideas and to experiment.
Konami always promote YU-GI-OH Online at Jump Festa in every year, During Jump Festa Period konamiplayer will appear only at Japanese Lobby.
