Time Out says
Standing right in the heart of the Kuramae neighbourhood, this shrine was first established in 1694, and assumed its current name in 1947. It's said to be the birthplace of kanjin sumo, i.e. wrestling tournaments held in order to raise donations for shrines and temples, and a memorial stele for the participants still stands on the shrine grounds. Traditional-style rakugo performances also take place here on occasion.
