The Constitution of UNESCO was signed on November 16th, 1945 in London and came into effect the following. Japan became a Member State in 1951, when at a time it still did not belong to the United Nations until 1956. Thus, this marked Japan’s memorable step in returning to international society. Actually, UNESCO activities in Japan had already begun in 1947, and these still remain a driving force in promoting private UNESCO activities. Moreover, Japan is said to be the first country to establish a private UNESCO association.
