When I was in Tokyo two weeks ago for Kana’s wedding, I came across some festival activity for the Kanda Matsuri.
The Kanda Myojin (big shrine) was just a few doors down the street from my hotel, and I emerged onto the street on a Sunday morning to find lots of mikoshi (portable shrines) being carried from small local jinja (shrines) to Kanda Myojin. It was very colourful!
