In 1946, the first General Conference of the postwar period was held at the Los Angeles Church. Eiji Suehiro was elected as the second Bishop of the Holiness Conference. He replaced Sadaichi Kuzuhara, who chose to remain in Chicago.

The Modesto Church was still under the care of the San Lorenzo Holiness Church. In March 1948, Yoshie Nakamoto, who was originally from the Seattle Holiness Church, was appointed as evangelist to the Modesto Church. She did not stay long and soon left for Japan as a missionary. The Modesto Church finally decided to close and sell its property, since only two families (the Kiyois and Ishidas) had returned to Modesto after the war. The proposal to close it was approved at the 1949 General Conference. The ministers and their churches in 1949, as well as the attendance statistics, are shown in Table 15.

In 1951, the JEMS Mt. Hermon Conference began with many young people attending from the OMS Holiness churches: thirty from the San Lorenzo Church, and some from the Baptist, Presbyterian and Free Methodist churches as well. (The JEMS Conference has grown with over 1,700 registered attendees in recent years.) Holiness members were an integral part of JEMS from its inception.

The first Holiness Midwinter Conference was held in 1952 at the Los Angeles Holiness Church. In the years following, this Conference which brought together the Nisei churches, has been held at many different locations.

In the early days of this transition period, pioneer work began in both West Los Angeles and San Jose. This period was also a time when many congregations realized their dreams of new church purchases and construction. The West Los Angeles Congregation purchased a church building and dedicated their facilities in 1955, after twenty years of pioneer work by Los Angeles Holiness members. San Fernando, after thirty years of pioneer work, saw their first church built; while San Lorenzo, Monrovia, and San Diego all added educational buildings. The Los Angeles Church purchased its present facility on Gramercy Place in 1951, while the Honolulu Church moved to its present site in 1958. The Executive Council was elected in 1959. The following year, the Los Angeles Holiness Church began a ministry in Orange County and the first meeting was held at the Okubo home with Eiji Suehiro as speaker.

The 1960 statistics for the churches, their English and Japanese department ministers, as well as the attendance at church activities, are shown in Tables 16 and 17. According to the worship attendance statistics in 1949, the total attendance of both departments was 263, while eleven years later, the total attendance for both departments was 808. The reasons for this rapid growth can be attributed to three major factors: 1) The return of evacuees from the Midwest, 2) the energetic evangelistic fervor of Nisei ministers and churches and, 3) by biological growth as Nisei families were just getting established.

On December 20, 1962, on the very day on which the San Diego Church had prepared a retirement banquet for him, George Yahiro died of a heart attack. The body of Christ was saddened at the loss of a dear Christian brother and faithful servant of the Lord. He had served as pastor in San Diego for sixteen years and had served in the Holiness Conference since its inception.

In June of the same year, Kanichi Niizato, the blind, lay evangelist who had served the Lord since 1922, passed on. With Sadaichi Kuzuhara officiating, Niizato had been ordained as a lay minister by Letty Cowman, the president of the OMS Japan Holiness Church.
