The 2020 Sanja Matsuri is technically happening in 2020, although due to COVID-19 counter measures, there will be no mikoshi (portable shrine) processions, so effectively there will be nothing to see. The information below applies to the festival as it usually happens.
This is one of the rowdier festivals with 2 million spectators expected to watch rather energetic, often tattooed gentlemen doing what can most accurately be described as ‘mikoshi jousting’. Whereas in other festivals the ‘portable shrine’ bearers may bounce the incredibly heavy mikoshi, during the Sanja matsuri,fundoshi clad participants often ride on the top and will try to knock opponents off.
The main parade happens on Saturday from 12 noon starting at Asakusa Shrine.
