When Kuzuhara joined the young people's group in Los Angeles, he was still a member of the OMS Holiness Church of Japan. Thus the budding congregation came under that church, even though there had been no prior contact with it.

To understand the history of the OMS Holiness Church of North America, a brief history of the OMS Holiness Church of Japan is helpful. In 1884, Juji Nakada met Charles and Letty Cowman, a couple who had dedicated their lives to a vision to go to the ends of the earth as missionaries. In 1897, Nakada received a holiness experience while at the Moody Bible Institute in Chicago. This experience served as the foundation for the OMS later. Soon thereafter Nakada returned to Japan with a strong desire from the Lord to build a Japanese Bible school like the one at Moody.

Following Nakada and under his direction, Charles and Letty Cowman left for Japan in 1901. The next year Ernest Kilbourne, a good friend of the Cowmans who shared their vision, joined them to begin a ministry with Nakada. That same year they established a Bible school in downtown Tokyo, which later was called the Tokyo Biblical Seminary. Today it is one of the largest seminaries in Japan with one hundred regular students.

As students graduated from the Bible school and settled throughout Japan, Nakada realized the need to organize and unify these graduates under a specific name and structure. He formed the Oriental Missionary Society in 1908, sensing that its mission was to help not only the Japanese people, but also neighboring nations such as Korea and Taiwan. Then in 1917 the OMS was reorganized as a church and was named the OMS Japanese Holiness Church; Nakada served as its first Bishop. From the very beginning the Holiness churches were greatly indebted to the OMS for their financial and spiritual help. For this reason the Japan Holiness Church included OMS in its name.

Kuzuhara remained a member of the OMS Japanese Holiness Church, and when he went to pastor the group in Los Angeles, he was appointed its California District Superintendent. The new congregation was named the OMS (Rafu) Los Angeles Church in 1921. Two years later, the church was renamed the OMS (Rafu) Holiness Church. OMS is still used in the name of the Holiness Church of North America, in remembrance of that early tie with that society.
