Anglican Church in Japan
First arriving in 1899, Tucker served for twenty four years as a missionary in the Nippon Sei Ko Kai, the Anglican Church in Japan. He served alongside the British Anglican Hugh James Foss, as joint bishop of the Osaka diocese, and later in 1913 was appointed Bishop of Kyoto. In 1903 he became President of St. Paul's College in Tokyo, an establishment that in 1922 gained formal recognition as Rikkyo University.
