Japan was settled thousands of years ago by people who migrated from China and Korea. The original religion of Japan is Shinto, which has intermingled with Buddhism, Confucianism and Taoism. The Christian churches form a small minority. The Protestant churches, through the national Christian council, have been active in promoting reconciliation between Japan and the Asian countries it had occupied, opposing the re-emergence of nationalism, re-militarization, and nuclear armament. There are a number of small but active Evangelical, Pentecostal and Holiness groups. The Japan Evangelical Association is affiliated with the WEA.
