The Union Solidarity and Development Party has won 193 of 209 seats in the lower house and 52 of 78 seats in the upper house after two rounds held on December 28 and January 11.
Voter turnout was about 55 per cent in each round, sharply lower than levels of about 70 per cent in the 2020 and 2015 elections.
Major opposition groups are not contesting the polls amid a civil war triggered by a 2021 coup that brought the military to power.
The United Nations, rights groups and the UK have denounced the polls as a sham exercise to perpetuate the military's hold.
Malaysia, which in 2025 chaired the 11-member Association of Southeast Asian Nations, which includes Myanmar, has said the bloc would not endorse the election.
"Whether the international community recognises this or not, we don't understand their perspective. The people's vote is the recognition we need," junta chief Min Aung Hlaing told reporters on Sunday, according to video broadcast on state TV.
The military has insisted the election is free of coercion and has public backing.
On Sunday, voters were casting their ballots in some 60 townships, including the large cities of Yangon and Mandalay.
Dressed in civilian clothes, Min Aung Hlaing earlier met voters at a polling station in Mandalay in a seemingly relaxed atmosphere, pictures from domestic media showed.
The 69-year-old general and acting president has indicated he is considering appointing someone to succeed him as armed forces chief and will likely move into a fully political role, a source has said.
Asked on Sunday about his possible role in the future government, Min Aung Hlaing said it was too early to say.
"Once the parliament is convened, they have their own procedures and methods for selection," he said.
While the junta has portrayed the election as a success despite the low turnout, residents of Myanmar's biggest cities have told Reuters of an atmosphere of fear and that many felt compelled to vote to avoid potential arrest or retribution.
One Yangon resident said polling stations in neighbourhoods where army officers and their families reside appeared to have a high turnout on Sunday, but few voters were seen in other areas.
The military took control of the impoverished Southeast Asian nation in a dawn coup on February 1, 2021, ousting an elected civilian government led by Nobel Peace Prize winner Aung San Suu Kyi.
The 80-year-old politician remains in detention and, like several other opposition groups, her National League for Democracy has been dissolved by the junta.
Fighting has continued through the election campaign and earlier voting in many parts of Myanmar, including air strikes around civilian areas in the border states of Rakhine, Shan and Kayin.
