In 1929 he represented Sri Lanka at the opening ceremony for the new Mulagandhakuti vihara at Sarnath, India, and in 1934 he visited Indonesia, the first Theravadan monk to do so in more than 450 years. During this opportunity he planted and blessed a bodhi tree in Southeastern side of Borobudur on 10 March 1934, and some Upasakas were ordained as monks. From that point on he travelled to many countries to conduct missionary work: Taiwan, Cambodia, Laos, South Vietnam, Singapore, Japan, Nepal, and Australia. In 1956, he visited the United Kingdom and the United States, and addressed a huge crowd at the Washington Monument. On 2 November 1960 Narada Maha Thera brought a Bodhi Tree to the South Vietnamese temple Thích Ca Phật Đài, and made many visits to the country during the 1960s.
