TOKYO — Japanese Prime Minister Sanae Takaichi's gamble that her personal popularity would lead to big election gains for her struggling party paid off hugely.
On Monday, she began the process of translating that new power, made manifest in a two-thirds supermajority gained in parliamentary elections the day before, into what she hopes will be sweeping conservative legislation that will shift Japanese security, immigration, economic and social policies.
The first steps include reappointing her Cabinet and pushing forward on a delayed budget and the votes next week that will reelect her as prime minister.
Takaichi told reporters Monday that her efforts are aimed at making Japan safe, strong and prosperous. ''We have no time to bask in the afterglow of the (election) victory.''
''Through this election, the people showed their determination to join me in the challenge,'' she said. ''I'm not afraid of making challenges and I will not sway. I will make a decision and accomplish it.''
Takaichi's Liberal Democratic Party, or LDP, alone secured 316 seats, comfortably surpassing a 261-seat absolute majority in the 465-member lower house, the more powerful of Japan's two-chamber parliament, officials said. That is a record since the party's foundation in 1955. With the 36 seats won by its new ally, Japan Innovation Party, the ruling coalition won 352 seats.
A smiling Takaichi placed a big red ribbon above each winner's name on a signboard at LDP headquarters as accompanying party executives applauded.
Despite the lack of a majority in the upper house, the huge jump from the preelection share in the more powerful lower house allows Takaichi to make progress on policies seeking to boost Japan's economy and military as tensions grow with China and she tries to nurture ties with the United States.
