TOKYO - Support for Japanese Prime Minister Fumio Kishida tumbled to its lowest since he took office, hit by anger over his ruling party's ties to a controversial church and a state funeral for former leader Shinzo Abe, an opinion poll showed on Monday.

Government support fell to 41 per cent, from 47 per cent in a previous poll late in August, to hit its lowest since Mr Kishida took office last October, identical to similar polls published last week, and down from 57 per cent in early July, the poll showed.

The share of those who did not support Mr Kishida rose to 47 per cent from 39 per cent, the poll by the Asahi Shimbun daily showed.

Links to the Unification Church, founded in South Korea in the 1950s, have become an increasing headache for Mr Kishida since July 8, when Mr Abe was killed by a suspect who blamed him for supporting the church, which he said had bankrupted his mother.

Mr Kishida's decision to hold a state funeral for Mr Abe on Sept 27 has also sparked anger, both over the ties of lawmakers of his ruling Liberal Democratic Party (LDP) to the church - Mr Abe among them - and the size of the funds earmarked for it.

In Parliament last week, Mr Kishida defended his decision on the funeral for Mr Abe, Japan's longest serving prime minister when he left office in 2020, but 64 per cent of poll respondents said they could not accept the prime minister's reasoning.

Opposition to the funeral rose to 56 per cent from 50 per cent in August, the Asahi said.
