Japan's parliament on Wednesday elected Yoshihide Suga prime minister, with the former chief cabinet secretary expected to stick closely to policies championed by Shinzo Abe during his record-breaking tenure.
He won 314 votes out of 462 cast by parliament's lower house members.
Suga supported Abe as Chief Cabinet Secretary for more than seven years.
Suga was born in 1948 and graduated from Hosei University in 1973 and obtained a Bachelor of Laws.
Suga, who on Monday was elected leader of the ruling Liberal Democratic Party, is viewed as a continuity candidate, saying his run was inspired by the desire to continue Abe's policies.
Among those expected to retain their jobs are key players such as Finance Minister Taro Aso and Foreign Minister Toshimitsu Motegi, along with Olympics Minister Seiko Hashimoto and Environment Minister Shinjiro Koizumi, the youngest at 39.
"I devoted my body and soul for the economic recovery and diplomacy to protect Japan's national interest every single day since we returned to power", Abe told reporters at the prime minister's office before heading into his final Cabinet meeting.
Kono is reportedly set to become minister in charge of administrative reform, a portfolio Suga considers particularly important.
Lee was prime minister in October when he attended the formal enthronement ceremony of Japanese Emperor Naruhito and also held talks with Abe.
Prime Minister Narendra Modi congratulated Suga on his appointment and said he was looking forward to jointly take the "special strategic and global partnership" between the two countries to new heights.
"In the longer term, because foreign investors' interest in Japanese stocks has been low, if he presses ahead with structural reforms and deregulations, that is a theme investors like and would be a positive surprise", Niihara added.
He has also said Japan may eventually need to raise its 10% sales tax to pay for social security, but not for the next decade.
Suga, who does not belong to any wing within the party and opposes factionalism, says he is a reformer who will break down vested interests and rules that hamper reforms.
