Ishiba, 68, has received criticism for handing out gift cards worth$ 100 ( US$ 673 ) to 15 new LDP lawmakers, a practice he has defended as legally acceptable and not a political donation.
Ishiba apologized on Friday after being grilled by opposition MPs in congress for” causing problems and stress some people” due to the voucher scandal.
Ishiba claimed that the gift cards, which he privately paid for, were meant to show respect to the people of politicians who took office for the first time following last year’s general election.
Ishiba once more apologized on Monday, stating that” there was a gap between the common vision” and his method of sending gift certificates.
According to the Asahi poll, 75 % of respondents thought the distribution of gift cards was problematic, compared to 23 % who thought it wasn’t.
According to the ballot of 1,137 voters, 32 % thought Ishiba may move down as top, compared to 60 % who felt he should remain in office.
In the Yomiuri poll, 75 % of respondents perceived gift cards as a problem, compared to 19 % who did not.
According to Chinese media reports, Ishiba’s declining support may prompt LDP members to attempt to pressure him to resign back of a vote in the top house in July.
Ishiba won a snap general election in October after being elected as prime minister, but angry voters in favor of corruption within the LDP and prices hit him.
In the worst election outcome for the LDP, which has been in power almost constantly since 1955, they deprive his coalition of a lot in the country’s effective lower house.
The group and its young coalition partner Komeito have needed criticism support to pass legislation since the vote.
In a third poll conducted by the Mainichi Shimbun, 23 % of voters voted for Ishiba’s Cabinet, down from 30 % in February, with 78 % calling the vouchers a problem.
