Three Non-Nuclear Principles significant person Eisaku Satō
Japan's Three Non-Nuclear Principles (非核三原則, Hikaku San Gensoku) are a parliamentary resolution (never adopted into law) that have guided Japanese nuclear policy since their inception in the late 1960s, and reflect general public sentiment and national policy since the end of World War II. The tenets state that Japan shall neither possess nor manufacture nuclear weapons, nor shall it permit their introduction into Japanese territory. The principles were outlined by Prime Minister Eisaku Satō in a speech to the House of Representatives in 1967 amid negotiations over the return of Okinawa from the United States. The Diet formally adopted the principles in 1971.
