What we know for certain is that the park opened again in 1986 and remained operational for 13 years, at which point it closed down for good. Nowadays the derelict attractions stand there alone in the middle of nowhere, gathering rust and being slowly consumed by the encroaching forest.

The trees here are nourished by souls.
By the way, we mean that "middle of nowhere" part literally, as Takakonuma can no longer be found on any official maps. It just isn't there.
