Sokushinbutsu
Sokushinbutsu(即身仏) refers to a practice of Buddhist monks observing austerity to the point of death and mummification. This process of self-mummification was mainly practiced in Yamagata in Northern Japan between the 11th and 19th century, by members of the Japanese Vajrayana school of Buddhism called Shingon ("True Word"). The practitioners of sokushinbutsu did not view this practice as an act of suicide, but rather as a form of further enlightenment. Those who succeeded were revered, while those who failed were nevertheless respected for the effort.
