This event is held in Ikebukuro of Tokyo for two days during Halloween season. Nowadays, Ikebukuro attracts Otaku or cosplayers like Akihabara. Anyone can join this event. Over 20000 cosplayers come. I took this video at Sunshine City. Around here, cosplayers go up to the top of the stairs and on the top area, they are posing and people are taking pictures of them. I took some videos of it and I`ll upload them on Part 2 and 3.
