In light of next year marking the 50th anniversary of the signing of the Japan-U.S. Security Treaty, Prime Minister Yukio Hatoyama said Thursday it's time the overall defense alliance is reviewed.
While stressing how the alliance is still a significant cornerstone in Japan's foreign policy, Hatoyama said his administration plans to promote a "multilayered development" of the alliance in the medium to long term.
"The Japan-U.S. Security Treaty will be marking its 50-year milestone," Hatoyama said on the second day of the Diet's question-and-answer period, responding to questions posed in the Upper House by Yoshimasa Hayashi of the Liberal Democratic Party.
