Chuseigaku was founded by the first president, Otondo Ohara when Kibigaku was accepted as the music at Services of Konkokyo.
In 1914 (in the 3rd year of Taisho), he wished to create the original music at Konkokyo Services and went to Tokyo in order to visit his old teachers who were "Gakusi" (professional players of "Kunaichou"). He received advice from them and studied hard. At last he developed "Chuseigaku" after one year and three months.
That melody is based on Gagaku and contributes to the solemn atmosphere at Services.
At first, it was named Shinji-gaku and then named Chuseigaku.
First president, Ohara composed the 1st Chuseigaku to the 23th and Netori (whose tunes are used when Officiant offers "Tamagusi" in the front of the altar. He passed away in 1942.
