About the Kanda Myojin Suzumi Matsuri
The Kanda Myojin Suzumi Matsuri began in 2016 as a summer festival centered on traditional bon dance and food stalls. Over the years it has increasingly connected with the surrounding neighborhood of Akihabara, a hub of the content industry, incorporating "anime-song bon dance" through collaborations with character content, various events held on the shrine grounds, and live performances by invited artists, making it a festival enjoyed by people of all ages.
