Abe's successor is likely to lead the LDP in a general election that must be held by October 2021 and could come sooner.
The weakness of fragmented opposition parties helped Abe hold power by leading the LDP-led ruling bloc to repeated election victories, and the LDP is expected to hold a majority in the next election.
But whether it can keep its nearly two-thirds majority in the lower house is a question and will likely hinge on the coronavirus, the economy, and the new leader's image.
If the LDP does badly, it may choose a new leader, reviving revolving-door premierships that plagued Japan before Abe's nearly eight-year rule.
