Mummified in life.
In the north of Japan, in Yamagata Prefecture, there is Sokushin-Butsu, where we find Buddhist mummies. But this death destination hides something even more macabre: the Buddhist monks you will see here mummified themselves while they were still alive.
This temple has the mummified remains of Shinnyokai-Shounin. According to information at the temple, Shinnyokai-Shounin was a Buddhist Monk during the Edo period who became a Sokushin-Butsu. These monks sacrificed their lives and practiced ascetic disciplines according to the temple. The monks would not eat grain, instead they ate nuts, tree roots, bark, wild plants, among other natural edibles. They then fasted on saltwater for 42 days and drank Urushi (An ingredient in lacquer) basically beginning the mummify process while still alive.
After self mummification, Shinnyokai-Shounin buried himself alive. Again, according to the temple, after 1,000 days of being buried, the body would be exhumed. Today, visitors can go to Dainichibou and see the mummified body of Shinnyokai-Shounin sitting there. You can partake in rituals. Just be warned, photographs of the mummy are not allowed.
