A circular swing in Kitakyushu, measuring 163 meters in circumference, was recognized Saturday as the longest in the world.
The structure erected in Hibikinada Green Park — which has 100 swings attached — was awarded Guinness World Record status after a commemorative event in which children were invited to give it a test workout.
"It's like a dream, having this many swings to play on," said 12-year-old Keisuke Hara.
The city government spent roughly ¥120 million to build the giant structure at a time when older swing sets throughout the country that no longer meet safety standards are being dismantled.
"There was a big demand for new swings from parents of small children," said an official.
The previous record-holder was a 133-meter-long swing set in the Netherlands that was recognized in 1998.
Hibikinada Green Park, which has an admission fee of between ¥70 and ¥150, also features a pony corral, kangaroo petting zoo, botanical gardens, cycling course and a barbecue space.
