Kishida, who is currently in New York to address the UN General Assembly, has defended the plan, insisting Abe’s record-breaking tenure and international standing mean he merits the ceremony.
The prime minister’s approval ratings have taken a hit over the decision, as well as a controversy over ties between politicians and the Unification Church.
The church, whose members are sometimes colloquially called the “Moonies” after Korean founder Sun Myung Moon, has been accused of pressuring believers to make sometimes ruinous donations – accusations it denies.

Tetsuya Yamagami, the man accused of shooting Abe, reportedly resented the church over his mother’s membership and hefty donations that left his family bankrupt.
While Abe was not a member of the church, he addressed affiliated groups, and his death caused renewed scrutiny of the sect and its political connections.
An investigation by Kishida’s ruling Liberal Democratic Party found that around half its lawmakers had ties to the sect.
He has pledged that the party will cut all links to the church, which has denied any wrongdoing.
Abe’s state funeral will be held at Tokyo’s Budokan, a large venue for concerts and sporting events.
World leaders, including US Vice President Kamala Harris and Australian Prime Minister Anthony Albanese, are among those expected to attend.
