On a cadaver mummified within 25 days

A male mummified adult cadaver was discovered in a deserted prefab-shed on September 16, 1983. He had been missing from August 22. So, it became clear that he was mummified within only 25 days after his disappearance. In Japan, the natural mummification of an adult cadaver is uncommon becuase of high humidity and it has been considered that the minimum period of mummification is 2 or 3 months after death. This mummy broke the record of this minimum period by a large margin. From the weather survey at the nearest meteorological station, it was speculated that a long spell of temperatures above 30°C without rainfall for a week as well as the minimum destruction of the cadaver from encroachment by insects contributed mainly to the mummification.
