Joam Yama (c. 1566 – 29 September 1633) was a Japanese Jesuit born in Tsu Province, at the center of Japan’s main island.
In August 1586, Yama joined the Society of Jesus and became the cleric of the Church of Yanagawa, which was ruled by the vassals of Don Francisco Otomo Sorin, a Christian feudal lord.
Since the Edo government had proclaimed anti-Christian Edicts in 1612, Yama and Adami were exiled to Macau with many other priests in November 1614.
[5][6] The Edo government had proclaimed anti-Christian Edicts again in 1619 and as a result, the oppression of Christians severely increased in Kyushu.
Joam Bautista Porro, a priest, brought a statement of encouragement written by Pope Paul V to Aizu in 1620.
