approximately one ton and cost ¥40 million ($390,760 in 2008) to construct. They are carried on four long poles lashed together with ropes, and each needs approximately 40 people dispersed evenly to safely carry them. Throughout the day, a total of about 500 people participate in carrying each shrine. Because of the importance of these three mikoshi, they are spectacles as they are carried through the streets. The areas immediately surrounding each shrine are busy with people, and as they are carried, they are shaken and bounced vehemently. This action is believed to intensify the power of the kami that are seated in the shrines and helps to bestow good luck upon their respective neighborhoods. It is not unusual for there to be someone standing on the poles supporting the mikoshi shouting and waving in order to help direct the people carrying the shrine. This sense of direction can be essential when trying to keep the one ton mikoshi from accidentally colliding with street-side shops and causing considerable damage. While the three primary mikoshi are the most important objects roaming the streets during the Sanja Matsuri, approximately 100 other smaller mikoshi are paraded through the neighborhood on Saturday.

This ceremony requires Asakusa Shrine's head priest to perform a ritual that moves the enshrined kami of the three men at Asakusa Shrine to the three mikoshi that will be paraded around the Asakusa during the weekend. By opening the small doors located on each mikoshi (the interior is obscured to the public by a small cotton curtain), the three spirits are invited into the miniature shrines where they will reside for the duration of the festival. The festival's more publicized beginning starts on Friday when the is held. This famous 19-block grand procession down Yanagi Street and Nakamise-dōri to Asakusa Shrine is an event that is used to energize the community. It is most known for its participants' lavish costumes, such as heron-hooded dancers, geisha and city officials wearing hakama (traditional Japanese clothing). Musicians, performers and dancers also parade down the streets of Asakusa in traditional Japanese attire during the procession. In the evening, six mikoshi from the most central neighborhoods are sent parading
