This Japanese Museum of Volcanology was built at the foot of an active volcano Asama in 1967.
In 1993, the museum was closed by the authorities due to lack of funding and lack of visitors.
At the moment, the museum of volcanology is abandoned for almost 20 years,
but all that is in the museum at the time of its closure, and is still in place.
I was not the first time wonder how the Japanese carefully treat other people's property.
