Princess Aiko departed the Imperial Palace in Tokyo on Saturday to attend the traditional Okihiki ceremony at Ise Shrine in Mie Prefecture [1].
The visit underscores the princess's growing role in fulfilling royal duties and maintaining the spiritual traditions of the Japanese monarchy. By observing the selection and transport of sacred timber, the princess connects the current imperial generation to the ancestral rites of the shrine.
The princess traveled from Tokyo Station via Shinkansen and Kintetsu rail to reach Ise City [1]. Her itinerary, spanning Aug. 1 to Aug. 2 [2], focuses on the "Okihiki" ceremony, where logs are hauled from the forests to be used in the construction of shrine buildings.
These activities are essential preparations for the next "Shikinen Sengu" [3]. This tradition involves the complete rebuilding of the Ise Shrine every 20 years [4]. The next full rebuilding cycle is scheduled for 2033 [3].
The ceremony carries significant historical weight for the imperial family. Emperor Naruhito participated in the same ceremony 19 years ago [3]. This visit follows a previous trip by Princess Aiko to the Ise region approximately two years ago [5].
During her stay, the princess will inspect the wood-processing activities required to ensure the structural integrity and traditional authenticity of the shrine's architecture. The process of selecting and moving the timber is a highly choreographed ritual that requires precise coordination between the shrine officials and the royal house.
Princess Aiko is expected to return to Tokyo on Sunday following the conclusion of her duties in Mie [1].
“The next full rebuilding cycle is scheduled for 2033.”
The princess's participation in the Okihiki ceremony serves as a public demonstration of continuity within the imperial line. Because the Shikinen Sengu is a 20-year cycle of renewal, these visits allow the royal family to maintain a lifelong connection to the shrine's preservation. Her presence signals her integration into the complex ritual calendar that defines the Japanese monarchy's relationship with Shinto traditions.
