1,800 volunteers spent the weekend hauling Hirosaki Castle’s 360-tonne keep more than 6 feet back toward its original position in Aomori Prefecture.
The move became possible after workers rebuilt an earthquake-damaged wall and returned all 2,185 stones to their original places.
Rotating teams used hikiya—an old Japanese method that shifts intact buildings on rollers or rails—to protect the historic structure during the relocation.
About 8,000 people applied for 1,800 slots, and hand-pulling will continue through the end of August with roughly 4,100 participants moving the keep more than 16 feet in total.
The current three-story keep dates to 1811 after an earlier five-story tower was lost to lightning in 1627; many Japanese castles were later dismantled or destroyed.
