The beginnings of the SaikuPrincess Oku , the earliest documented Saio. Excavations have revealed that the Saiku was made larger and more elaborate in the 8th century, though its full size has yet to be established.
In the neighborhood of the Saiku site are sites of many pottery workshops that produced hajiki, a type of reddish-brown, unglazed earthenware. Some theories suggest that these pottery workshops were associated with the Saiku.
On display here are examples of hajiki retrieved from the site of the hajiki workshops. These are shown alongside examples of 7th and 8th century hajiki retrieved from the Saiku site.
On display is a replica of a wooden tablet excavated at Asuka, one of the ancient capitals. The tablet is inscribed with the name Princess Oku , one of the imperial princesses who became a Saio.
