The Protestant union of 1941
In 1941 more than 30 Protestant denominations formed the United Church of Christ in Japan. The church’s history places the union within both the international church-unity movement and state control under the Religious Organizations Law. It did not merge Catholicism and Orthodoxy into that Protestant body.
Different organizations after the war
Some Protestant churches left the wartime union and rebuilt earlier denominations; others remained united, and new groups emerged. The dispatch of a papal representative to Japan resumed in 1949 after a postwar interruption. The Orthodox Church in Japan became autonomous in 1970, a status distinct from full independence.
A later constitutional guarantee
Removing prohibitory notices in 1873 and constitutional religious freedom were separate stages. Article 20 of Japan’s Constitution, effective in 1947, guarantees freedom of religion, rejects compelled participation in religious rites and restricts religious activity by the state and its organs.
