Prime Minister Shinzo Abe marked his 2,798th consecutive day in office Sunday, tying him with his great-uncle, Eisaku Sato, as the prime minister with the longest continuous term in office.

But with criticism mounting over his handling of the coronavirus crisis, and questions growing about his health and the post-Abe era, the prime minister faces tough questions about what he might still be able to accomplish before stepping down in September 2021.

Abe, who was prime minister from 2006 to 2007, returned to power in 2012. He now has the same number of consecutive days in the top position as Sato, who served as prime minister between 1964 and 1972.
