The Japanese political world was rocked Sunday after media reports emerged that Prime Minister Shinzo Abe plans to dissolve the Lower House as early as Sept. 28 and call a snap election to take advantage of a disorganized opposition.

Major media outlets, including Kyodo News, Asahi Shimbun, NHK and Sankei Shimbun, all reported that Abe is considering dissolving the powerful Lower House soon and would call a general election next month, possibly on Oct. 22 or 29.

Abe is likely to decide on a specific date for the election after returning to Japan from a diplomatic tour to New York on Sept. 22, the reports said, quoting unnamed sources in the Liberal Democratic Party-Komeito ruling coalition.
