One Mission Society

One Mission Society (formerly known as OMS International and, before then, known as the Oriental Missionary Society) is an Evangelical Christian missionary society founded in 1901 by Charles and Lettie Cowman, Juji Nakada, and Ernest A. Kilbourne. 

"OMS was birthed in a storefront building in the heart of Tokyo, Japan. In 1901, American missionaries Charles and Lettie Cowman "partnered with a Japanese pastor, Juji Nakada, holding Christian evangelistic meetings for 2,000 consecutive nights. Before long, Japanese churches were organized, and the new association, the Japan Holiness Church (JHC), grew rapidly."[2] Not long after their arrival, in 1902, Charles' former co-worker, first conversion, and best friend, Ernest Kilbourne, and his family, joined them. 

Born on March 13, 1868, Charles E. Cowman grew up in the church, but he didn't accept the call to spread the Gospel until much later in life. At 15 Charles left home for a job in telegraphing, where he quickly impressed others with his ability. It was during this time that he would meet his future wife and develop a deep friendship that quickly turned to love. The couple would marry when she was just 19 and he 21.  

After living in Colorado for one year of marriage to escape the noise of living in the city, they spent the next ten years in Chicago where Charles continued his work in telegraphy. It wasn't until 1894 that Charles finally accepted the call the Lord had placed on his heart from spreading the Gospel. Accepting this call lit a fire in Charles. He fervently tried to reach his coworkers one by one, and he found great success.

It wasn't long before Charles felt called to spread the Gospel in Japan. When he brought up this calling with Lettie, she told him that she had felt the same calling 6 weeks prior to his announcement. 

Stepping out in faith and living financially through God's grace and provision, the couple moved to Japan in 1901 to partner with Juji Nakada.  

Charles never lost his passion for reaching people, in fact, it only continued to get stronger. It weighed heavy on Charles that so many people still hadn't heard the Gospel, so he worked himself sick trying to reach everyone in Japan.  

Eventually, he could go on no longer, and he went to be with the Lord on September 25, 1924. 

Born on March 3, 1870, Lettie B. Cowman would meet her future husband for the first time when she was just a baby. But, when she was 13, and he was 15 they met again. Charles was living away from home for the first time and the two befriended each other. It soon become apparent that they were destined to be sweethearts. At ages 19 and 21, they married and moved to Colorado for their first year of marriage. After Lettie became severely ill, it was clear that they could no longer live in such a high altitude, so they spent the next 10 years of their marriage in Chicago.
