After going to Kanda Matsuri, the next week, on Saturday May 15th 2010, I went to Sanja Matsuri (三社祭) in Asakusa. Sanja Matsuri is also one of the three great Shinto festivals in Tokyo. (Wikipedia) The festival is held in honor of the three men who established and founded Senso-ji (浅草寺). In the festival, the main attraction was the mikoshi, many people of different groups carried mikoshi with different colors. The mikoshis were decorated and there were golden sculptures (usually golden birds) on the top of the mikoshis, and they were carried by people around the Asakusa area. Because I went to the Sanja Matsuri on Saturday, I could only see the small mikoshis, not the big three mikoshis owned by the Asakusa Shrine which would appear on Sunday, the final day of the Sanja Matsuri.
Besides the small mikoshis carried by adults, there were even smaller mikoshis carried by children.
There were also musical floats parading through Asakusa during the Sanja Matsuri.
