[UPDATE: Oct 11] Due to Typhoon Hagibis, expected to bring strong wind and heavy rain throughout Tokyo the weekend of October 11 and 12, the event has been cancelled.
Celebrated since 1968, this two-day festival takes place in front of JR Ikebukuro Station, with dozens of mikoshi (portable shrines) being paraded along the streets. The festivities include taiko drumming, yassa and kappere dance performances, an Okinawan eisa dance show, plus a fife and drum parade. The second instalment of the Fukuro Matsuri happens two weeks later (Oct 12-13), with over 100 different teams of yosakoi dancers parading through the neighbourhood.
