Nippon Post Jimmy Carter at Tokyo Seven Nation Economic Summit

NIPPON POST on 15 January 1975 issued to two stamps celebrating the American tour of Emperor Hirohito and Empress Nagako. The two stamps depicted the national flags of Japan and the United States, trimmed with cherry blossoms.

The same stamps were used in 1979 when U.S. President Jimmy Carter met Japan Prime Minister Masayoshi Ōhira. The visit corresponded with the Tokyo Seven Nation Economic Summit, which was held on 24 June 1979. The special cachet and postmark cancellations highlighted the event.
