The approval rate for Prime Minister Shinzo Abe's Cabinet has dipped to 47.6 percent, a Kyodo News survey showed Sunday, down from 50.5 percent in the previous poll in mid-May, amid criticism over handling of a financial report that indicated flaws in Japan's pension system.

In the nationwide telephone poll conducted Saturday and Sunday, 53.2 percent approved of Abe's recent visit to Iran, amid the country's standoff with Washington over a 2015 deal that curtailed Tehran's nuclear program, while 33.5 percent did not approve.

Respondents in the weekend survey were reached via phone numbers randomly generated by computers.
