Abe's Cabinet disbanded early in the day as a ritual first step. The parliament was to convene in the afternoon to elect Abe as prime minister. Abe is due to then appoint a new cabinet.
Japanese media reported that the cabinet ministers will mostly remain the same, apart from the defense minister, Akinori Eto. Many of the ministers were appointed in a reshuffle in early September.
Eto was one of several cabinet ministers whose political funding reports were questioned by opposition lawmakers during the recent parliamentary session. Two resigned but were re-elected anyway. The questions over political finance pulled Abe's popularity ratings lower and were likely a factor in his decision to call the snap election.
Analysts said Eto's handling of the questions was seen as too weak, and that Abe planned to appoint a stronger figure to help handle anticipated fierce questioning over defense-related issues in the next year's parliamentary debate.
The election's outcome was seen as a public endorsement of Abe's strategy for reviving the economy, despite a record low turnout. Abe, who took office two years ago, could stay in office for another four years but must call the next election by December 2018.
