What is Jaki?
In Buddhism, it is expressed as a "demon" that causes disasters and is stepped on by the four heavenly kings, and these demons are also considered to be saved in Buddhism.
The four heavenly kings wear armor and carry weapons to serve Teishakuten and protect the north, south, east and west.
And in the temple, it is placed at the four corners of the Sumeru altar where the principal image is enshrined.
From the east to Jikokuten, to the south is Zouchoten, to the west is Koumokuten, and to the north is Tamonten.
