It is not necessary to reiterate that the United States is Japan's only ally. The Japan-U.S. Security Treaty was signed on September 8, 1951 by my grandfather Prime Minister Yoshida Shigeru. On the same day, the San Francisco Peace Treaty was concluded, which marked Japan's return to the international community. The following year, on April 28, 1952, the Treaty officially came into force. It was revised in 1960 and remains in effect to this day. Indeed, the alliance has continued for more than 70 years.
