Nearly one in four roller coasters and similar rides in Japan have never undergone maintenance checks, the transport ministry said Wednesday.
The Land, Infrastructure and Transport Ministry made the discovery after ordering emergency checks on 306 amusement park rides nationwide following the death of a young woman in a roller coaster accident earlier this month in Osaka Prefecture.
Of the 306 rides, it was found that the amusement parks operating 119 of them had failed to conduct maintenance checks in the past year.
