On Thursday and Friday, enthronement rituals concluded with The Daijosai (Great Thanksgiving Ceremony), a festival that dates back to at least the 7th century and is performed by a new emperor the autumn following his enthronement. This festival was held in temporary Shinto shrine compound called the Daijokyu, composed of nearly 30 buildings (about 6,500 square meters) specially built in the East Gardens of the Imperial Palace grounds for the Daijosai. For those of you in Tokyo, this will be opened to the public free between November 21 and December 8 before being dismantled, the wooden building materials being recycled for parks and disaster-prevention facilities.
The Imperial Household Agency purchased specialty vegetables, fruit and seafood from each of Japan’s 47 prefectures for this festival. Rice was cultivated in two rice paddies in the country’s east and west with the locations determined by divination using turtle shells; special fabrics- hemp from Tokushima and silk from Aichi were also provided.
The day began with Empress Masako arriving at the royal palace (earlier than the emperor, to prepare her elaborate costume) in a cream silk jacquard printed bumper hat.
For the ritual, the emperor wore white sokutai robes with the distinctive black kanmuri hat.
The empress wore a traditional “junihitoe” multi-layered kimono, this one in white and peach, along with this Heian Era costume’s triple pronged silver headpiece.
The Imperial Princess (I’ve spotted Kiko, Mako, Kako and Nobuko and suspect the other Mikasa and Takamado princesses also attended) wore a similar metal headpieces but with more delicate, beaded triple prongs (following a tree shape, I think?) and silk cord that loops around the top of the head and hangs down in a multi-bowed tassel on either sides of the face.
The event concluded with a banquet, hosted by the emperor and empress. The Imperial Princesses were in attendance, the Akishinos in cuffed calot hats, Princess Nobuko in a teal button percher, Princess Akiko in a brimmed cream hat, Princess Yoko in a pale blue percher, Princess Hisako in a green saucer with cream brim and flowers around the raised back, and Princes Tsuguko in a petal trimmed peach bumper.
