The 2025 Japan International Exposition (Osaka-Kansai Expo), held over six months from April 2025, attracted approximately 25,578,900 general visitors. The venue, surrounded by the iconic large roof ring, was filled with unique pavilions, each showcasing its own vision of the future society.

Takekoma Shrine is located about 20 minutes south of Sendai Station on the Tohoku Main Line in Iwanuma City, a city surrounded by lush countryside.
