Approximately 1,000 workers and volunteers helped tow the 400-tonne keep of Hirosaki Castle toward its original position on Sunday [1], [2].
The event marks a critical step in returning the historic structure to its rightful place after more than a decade of displacement. The effort combines traditional community participation with modern engineering to preserve Japanese architectural heritage.
Located in Aomori Prefecture, the castle keep was originally shifted 80 meters [4] in 2015 to facilitate essential repairs to its supporting stone walls [1], [2]. The structure has remained in this temporary position for 11 years [1].
During the event on Aug. 23, the crowd worked together to move the massive keep approximately 109 cm [1]. This manual effort is part of a phased process to reverse the 2015 relocation. The project ensures that the structural integrity of the stone walls is maintained while returning the tower to its historical coordinates.
Organizers coordinated the movement of the 400-tonne structure [1] to ensure safety and precision. The use of a large volunteer force serves as both a practical means of movement and a public engagement effort to connect the local community with the preservation of the site.
The restoration of the stone walls, which necessitated the original move, was required to prevent collapse or further degradation of the castle's foundation. By moving the keep back, officials aim to restore the original layout of the fortification.

The relocation of the Hirosaki Castle keep demonstrates the complex balance between modern structural preservation and historical authenticity. By moving the tower 80 meters in 2015, engineers were able to stabilize the foundation without risking the collapse of the keep. The current effort to return the structure to its original site signifies the completion of those repairs and a commitment to restoring the castle's original architectural footprint.
