These are taken from the abandon Takakonuma Greenland Park of Japan. The park opened in 1973 and shut down only after two years of service; common lore says that the rides were due to many accidental deaths. It was reopened in 1986 and closed thirteen years later. The park is not located on any maps and is now surrounded by radiation due to the Fukushima meltdown after the tsunami.
I’m fascinated with stuff like this, especially Chernobyl.
