Indonesian Reformed Evangelical Church in Tokyo is served by Rev. Erianto Chai, M. Th., M. Eng with his family. Before his calling, REv. Erianto Chai had lived in Japan for 11 years, while his wife, Vicar Verawati Halim, had stayed for 9 years. After their marriage, they moved to Indonesia and underwent Theological Study in Sekolah Tinggi Teologi Reformed Injili Indonesia (STT-RII). In addition to acquiring Bible’s knowledge during their study, they served in ministry. After the study, they were sent by Indonesian Reformed Evangelical Church to Japan as missionaries.
