In the Kogosho, there is a reproduction of the Azumasoobi dance performance, which was originally the commonalty performance of Eastern Japan. It was then adopted in the Imperial Court in the Heian Period (794-1185).
Later on, you will see photos of real dancers and musicians performing the Azumaasobi, in the Shinmikurumayose stage (where you saw the female dancers mannequins before).
