History

Historical Context

December 1967 Prime Minister Eisaku Sato declared Japan’s Three Non-Nuclear Principles, tying the pledge to the U.S. nuclear umbrella and opposition to 1,200 warheads in Okinawa. He later secured Okinawa’s return in 1972 and signed the NPT in 1970. In August 2026 Prime Minister Sanae Takaichi’s Hiroshima-Nagasaki visits and Defense Minister Shinjiro Koizumi’s security warning revive Sato’s legacy as Japan weighs a policy shift.
