A dance floor in those days!!
This is a photo in a museum in Tokyo. These small dolls and latest survey show that some Japan cities had some discos in those days. The doll in the center is dancing to the rhythm of drum.
Oh, sorry. Just kidding:-)
Actually these were stored in Horyuji Temple, an old and famous temple in Japan. They may be something of a kind of gods.
Have a nice weekend.
