Support rate for the Cabinet of Japanese Prime Minister Shinzo Abe has edged down almost 2 percent to 70.9 percent, compared with 72.1 percent in the previous poll last month, according to a Kyodo News survey showed on Sunday.

It was the fourth time that the Cabinet approval rating has surpassed 70 percent in the monthly surveys since Abe's Liberal Democratic Party (LDP) took power in December.

Asked which party they will vote for in the proportional representation section of the upper house election this summer, 6. 8 percent of respondents said they would vote for the opposition Democratic Party of Japan, while 5.7 percent of the respondents said they would support the Japan Restoration Party.

Abe's LDP secured the highest approval rating at 44.4 percent, according to the survey.
