The Institute of Japanese Classics Research (皇典講究所, Kōten Kōkyūsho) was a central government organization for the training of the Shinto priesthood in Japan.

[7] This school was opened as an institution to carry out the indoctrination of the Imperial Way to the masses as part of the religious policy of the Meiji era, when State Shinto was established.

[14] When the foundation eventually developed into an incorporated foundation and the appearance of Shinto as the state religion came to an end and management became difficult, it was jointly run by private organizations related to shrine with the cooperation of Shintoists, along with the Dainippon Jingikai (大日本神祇会) and Jingū Hōsaikai (神宮奉斎会), until then.

[15] Around the 10th year of Meiji (1877), during the Bunmei-kaika era, the slump of the Proclamation of the Great Doctrine and the subsequent controversy over the ritual gods led to a proposal from within the government to establish a school focusing on Kokugaku research, and the subsequent controversy over the establishment of a school for Kokugaku studies.

[20] On January 25, 1946 (Showa 21), after the end of World War II, the GHQ dissolved the Imperial Academy and Kokugakuin University was established.

The General Judge Noboru Hitoshi, who has been entrusted with the responsibility of presiding over the ceremony, addresses the staff and students in a friendly manner.

On June 3, the school site was set at the residence of former Hatamoto Hayato Akimoto, 5-8 Iidacho, Kojimachi-ku, Tokyo, and on August 21, an "Application for the Establishment of an Imperial Institute for the Study of the Imperial Law" was sent in the name of Vice President of the Shinto School Hei Iwashitara Yamada Akiyoshi, the Vice President of Shintoism, and was approved on the 23rd of the same month.

The director, Akiyoshi Yamada Minister of Justice, founded the Japan Law School [ja] in 1889 (Meiji 22), followed by the Kokugakuin in the following year.

1889 The Constitution of the Empire of Japan was enacted, which shifted the focus from imperial studies to government-oriented Higher education system.
