Sanja Festival (三社祭)
Time: Mid to Late May
Prefecture: Tokyo
Location: Asakusa Shrine, Sensōji Temple, Nakamise Shopping Street

The Sanja Matsuri is renowned as one of Tokyo's more spirited festivals, drawing around two million spectators. It features lively and occasionally tattooed participants engaging in what can be aptly described as "mikoshi jousting." While in other festivals mikoshi bearers may bounce the heavy portable shrine, at Sanja Matsuri, participants don fundoshi (loin cloth) attire, riding atop the mikoshi and attempting to knock off opponents, despite it being strictly prohibited.
