Fifty years of membership in the Organization for Economic Cooperation and Development have seen Japan rise to one of the world's largest economies.

Japan joined the OECD on April 28, 1964. In the 50th anniversary year, Japan is hosting the organization's ministerial council meeting on May 6-7. Prime Minister Shinzo Abe plans to attend the session and deliver a keynote speech.

Half a century ago, accession to the club of wealthy nations was a significant event that cheered up public sentiment in a country that had just entered a period of rapid economic growth after rebuilding itself from the ashes of the war's devastation.
