Expoland, located in Suita, Japan. It was opened as the amusement zone at the International Exposition in 1970 ( Expo '70) in Osaka and thrived for over 30 years as an amusement park. There were more than 40 rides and attractions, 19 restaurants and shops.
On May 5, 2007, a 19-year-old university student from Higashiomi, Shiga was killed and nineteen other guests were injured when the Fujin Raijin II derailed at Expoland. Initial reports said that forty people were injured, with thirty-one being taken to 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 December 9, 2007, citing a lack of customers. On February 9, 2009, its owners finally decided that the park was closed down for good.
