Sanae Takaichi, 64, won a parliamentary vote to become Japan's 104th prime minister on Oct. 21, making history the country's first female to hold the position.
The leader of Japan's ruling Liberal Democratic Party (LDP), Takaichi secured 237 votes in the first round of voting, more than the 233 needed for a majority in the 465-seat Lower House, Japan Times reported.
Her victory was welcomed with thunderous applause from the lawmakers.
Subsequently, she also claimed the majority vote in the Upper House, BBC reported.
The vote came a day after LDP and the right-wing Japan Innovation Party (JIP) formed a new coalition.
JIP is the third-largest party in the Lower House, also known as Japan's House of Representatives, with 35 seats, according to Japan Times.
LDP holds the most number of seats, with 196, followed by the Constitutional Democratic Party with 148.
Conservative leanings
Formerly the country's economic security and internal affairs minister, Takaichi has been widely dubbed the protege of the late Japanese prime minister Shinzo Abe.
She has pushed to revive Abe's economic policies, including high public spending and cheap borrowing, according to BBC.
A staunch conservative, she is against same-sex marriage, and has previously opposed legislation allowing married women to keep their maiden names, arguing that it undermines tradition.
In early October, she was elected the leader of LDP in her third bid for the role, and in her victory speech, called for the lawmakers in the party to"work like a horse" for the country.
New cabinet
Later on Oct. 21, Takaichi will formally be appointed prime minister by the emperor at the imperial palace, and go on to form her cabinet, Nikkei Asia reported.
Despite the new coalition, no lawmakers from JIP are expected to be part of the new cabinet, according to Japan Times.
An admirer of former United Kingdom Prime Minister Margaret Thatcher, Takaichi previously hinted during her campaign that she would appoint a high number of female lawmakers if she won the election.
Local media reported that Satsuki Katayama, a former finance ministry official, is likely to be named Japan's first female finance minister, according to Bloomberg.
Takaichi's predecessor, Shigeru Ishiba, had only two women in his cabinet of 20.
Takaichi is expected to visit Kuala Lumpur as part of the Asean Summit from Oct. 26 to 28.
On Oct. 21, Malaysian Prime Minister Anwar Ibrahim congratulated Takaichi on her election in a , and added that he looked forward to welcoming her for the summit the following week.
