Fukagawa Hachiman Matsuri (2015)

Known as one of the three ‘great festivals’ of Edo, the matsuri at Fukagawa's Tomioka Hachimangu shrine takes place annually, but is celebrated in all its glory only once every three years (next time is 2017). It's still worth heading over on any given year though, as the mikoshi (portable shrine) processions, rowdy dance performances, and people throwing water on the participants (on Sunday Aug 16 only) make for plenty of fun.
