TOKYO/NARA, Japan—Japan's conservative coalition government increased its majority in the upper house of parliament in an election on Sunday, two days after the assassination of dominant politician and power broker Shinzo Abe.
Abe, Japan's longest-serving modern leader, was gunned down on Friday during a campaign speech in the western city of Nara in a killing that stunned a country where political violence and gun crime are rare.
Prime Minister Fumio Kishida's Liberal Democratic Party (LDP), of which Abe remained an influential lawmaker, and its junior partner Komeito won 76 of the 125 seats contested in the chamber, from 69 previously, according to an exit poll by public broadcaster NHK.
The LDP won 63 seats, up from 55, to win a majority of the contested seats, but not enough to take a single majority overall.
Elections for parliament's less powerful upper house are typically a referendum on the sitting government. Change of government was not at stake, as that is determined by the lower house.
But the strong showing could help Kishida consolidate his rule as he looks to steer Japan's recovery from the COVID-19 pandemic, keep a lid on rising consumer prices, and bolster defense at a time of tension with its neighbor China.
Final results are due on Monday afternoon.
"It's significant we were able to pull this election together at a time violence was shaking the foundations of the election," Kishida, an Abe protege, said after the exit poll.
"Right now, as we face issues including the coronavirus, Ukraine, and inflation, solidarity within the government and coalition parties is vital," he added.
The party held a moment of silence for Abe at its Tokyo headquarters as members waited for results to come in.
The gains may allow Kishida to revise Japan's pacifist constitution, a dream Abe never achieved.
Parties open to revising the constitution maintained their two-thirds majority in the upper house.
The Abe EffectShigenobu Tamura, a political analyst and former LDP staffer, said Abe's assassination may have bolstered the ruling party's support in "hotly contested districts."
Other analysts said the exit poll was broadly in line with pre-election surveys. Voter turnout was expected to rise to 51.58 percent from 48.8 percent at the last upper house election three years ago, Kyodo news agency estimated.
The Japan Innovation Party, a conservative opposition party, won 12 seats, extending its overall holdings in the upper house to 21 seats.
Abe was stumping for LDP candidate Kei Sato in Nara when he was shot from close-range by a man with a homemade gun.
The ex-premier "was shot in an act of terrorism in the midst of our election campaign," Sato said after the exit poll projected he would win his seat. "We continued our campaign in the belief that we must not cave into terrorism or fear it—we must overcome it."
Nara police said on Sunday they had seized a motorcycle and a vehicle belonging to the suspect, 41-year-old Tetsuya Yamagami, who was arrested at the scene.
Police said that they retrieved trays wrapped in aluminium foil from the vehicle, which they said the suspect told them he had used for drying gunpowder, and wooden boards with holes that he said he had used for test-firing his crude weapon made of wood and metal.
The suspect told police he spent months planning the attack, accusing the former prime minister of links to a religious group he blames for his mother's financial ruin, according to Japanese media.
Police said the suspect told them he arrived at a station near the scene more than an hour before the attack and passed time by visiting shopping complexes.
