Millions in Japan are voting in a snap election called by Prime Minister Sanae Takaichi, whose coalition is predicted to clinch a decisive win.

Just months after she was elected by lawmakers, Takaichi decided to go to the polls to seek the public's mandate.

Polls show her Liberal Democratic Party's (LDP) coalition with the populist Japanese Innovation Party could bag up to 300 of the 465 seats in the Lower House, marking a turnaround for the LDP which lost control of both chambers of Japan's parliament last year.

The conservative leader has won over some voters by offering tax cuts and subsidies, but critics say these will deal a heavy blow to Japan's sluggish economy.

Nearly 4.6 million people had cast early ballots as of a week ago, down 2.5% from the previous election in 2024, with the decline attributed to heavy snow in the northern and western regions.
