Shirayanagi actively promoted ecumenical dialogue with other Christian communities and interreligious conversation with Buddhist and Shinto traditions present in Japan. He regarded respectful dialogue as important for mutual understanding and for the Church’s witness in a plural society, supporting projects and meetings that brought different faith communities together.
