Princess Aiko visited the Toba Aquarium in Mie Prefecture to observe biodiversity conservation activities and sea otter demonstrations [1].
The visit is part of a larger official Imperial journey to the region, which includes a pilgrimage to the Ise Shrine and attendance at the "kihiki" ceremony [4]. This appearance highlights the Imperial family's continued engagement with environmental preservation and regional cultural traditions.
Princess Aiko arrived in Mie Prefecture on Aug. 1, 2026 [2]. According to reports from ANNnewsCH, she visited the aquarium on Aug. 2, 2026 [1], though other reports suggest the visit took place the afternoon of her arrival [2]. During the visit, the princess watched the aquarium's two sea otters [3] perform a specific feeding demonstration known as the "ika ear jump" [1].
Staff provided the princess with a detailed briefing on the facility's work regarding biodiversity conservation [1]. The "ika ear jump" is used by the aquarium as a method for health checks during feeding [4]. Following the demonstration, Princess Aiko said the performance was a "great success" [1].
Beyond the aquarium visit, the trip is centered on the Ise Shrine. The princess is participating in activities related to the Shikinen Sengu, a tradition where the shrine is rebuilt every 20 years [1]. The "kihiki" ceremony involves the traditional pulling of sacred logs used in the construction of the shrine [4].
“"Great success"”
Princess Aiko's visit blends the Imperial family's traditional religious obligations—specifically the 20-year cycle of the Ise Shrine's reconstruction—with a modern emphasis on environmental stewardship. By highlighting biodiversity and animal welfare at Toba Aquarium, the princess signals a commitment to scientific conservation that complements the spiritual heritage of the Ise pilgrimage.
