About 100 people aged between 7 up to those in their 50s participated in a race last week to wipe Japan's longest existing wooden hallway with dustcloths in Seiyo, Ehime Prefecture.
An 11-year-old girl won the championship for elementary school children.
The winner, Yuri Oshika, finished wiping the 109-meter-long hallway in 24.8 seconds.
"I'm so happy. I will practice more and finish with a faster record next year," she said.
The building was formerly an elementary school and is now a rice museum.
The Friday race, the 10th, was organized by the local chamber of commerce and industry.
