On May 5, 2007, 19-year-old Yoshino Kogawara from Higashiomi, Shiga was killed and nineteen other guests injured when the Fujin Raijin II derailed at Expoland in Suita, Osaka. Initial reports said that forty people were injured, with thirty-one being taken to the hospital. An investigation revealed that the ride derailed due to a broken axle. None of the ride vehicle's axles had been replaced for fifteen years. Following this accident, similar coasters at other Japanese parks were voluntarily shut down and inspected to see if they could also have the same axle flaw. Expoland was cited by authorities for faulty maintenance when similar axle cracks were found on a second train a month later.
The park reopened after the accident, but closed again on the 9th of December 2007, citing a lack of customers. It is currently undergoing major renovations.
