The Chosun Shrine was established in 1925 at the foot of Mt. Nam in Seoul. Japanese imperialist believed that it was of vital importance to propagate Shrines as a temple to worship. That was why from 1912 Japanese concentrated their energy to create this custom, it finally realized to the Chosun Shrine. Japanese Shrines - consummated with the Chosun Shrine - became the basis of Japanization policy until the independence of Chosun in 1945. These shrines became common places with the ritual of the salutation to Japanese king as a living god. This paper tried to find reasons why Chosun people worshiped the shrines including the Chosun Shrine. The final outcomes are as following Frist, to make Japanese emperor fixed as a heavenly king, the salutation to the emperor was an useful method. Japanese believed that if the king become the religious idol, Chosun people would like to follow him even at the cost of their lives. That is why Japanese founded the Chosun Shrine and made people recite the Education Edict with solemn manner. Second, in the repeatation of the process of worship the Chosun Shrine was used as a method of assimilation policy. Chosun people came to Chosun Shrine, purified their mind and body with the regulations of the temple, and worshiped in front of the idol. This ritual did not occur at one time but every holiday, for someone, everyday. This meant that the Shrine became daily places where Japanize Chosun people. Third, Japanese used schools as a crucial media to the salutation of shrine. Every morning, students recited the Education Edict and visited Chosun Shrine and saluted to the east where Japanese king lived. This meant ``making emperor`s people`` was done intensively in school. Consequently even superficially, students had to attend this Japanization. Without this education, social success would have been impossible.
