In 1890 he began publication of the bimonthly magazine Nihon Hyōron. His first important theological work, Shinri Ippan (Universal Truth), was published in 1884. He participated as a leader of growing importance in the organizational development of the Nihon Kirisuto Kyōkai (The United Church of Christ in Japan).
Uemura showed his independence of spirit when he published a statement in support of Uchimura Kanzō, after the famous disloyalty incident in 1891. Uemura was the first to propose the ordination of women as elders in the Nihon Kirisuto Kyōkai and in spite of opposition was able to secure the adoption of this policy, perhaps the first instance of the ordination of women as elders in the history of the Presbyterian-Reformed tradition anywhere in the world.
