The term "daijō-tennō" (大嘗天皇) refers to the Japanese emperor who performs the Daijō-sai, a significant Shinto ceremony. This event marks the emperor's ascension to the throne and involves offering newly harvested rice to the deities, symbolizing the emperor's role as a mediator between the gods and the people. The Daijō-sai is traditionally held in the first year of the emperor's reign. It is a vital ritual that emphasizes the importance of agriculture and the connection between the emperor and the land. The current Emperor of Japan participates in this ceremony, which reflects Japan's rich cultural heritage and Shinto beliefs.
