After Tuesday's funeral, Abe's body will be driven past some of Tokyo's political landmarks, including the prime minister's residence -- known as the Kantei -- and the country's parliament, the Diet.
Public memorials are expected to be held at a later date, with suggestions that top foreign political leaders could attend, but no details have yet been announced.
Abe was the scion of a political family and became the country's youngest post-war prime minister when he took power for the first time in 2006, aged 52.
He resigned in 2020 at the end of his second stint after suffering health problems.
His hawkish, nationalist views were divisive, particularly his desire to reform the pacifist constitution, and he weathered a series of scandals, including allegations of cronyism.
But he was lauded by others for his economic strategy, dubbed "Abenomics", and his efforts to put Japan firmly on the world stage, including by cultivating close ties with former US president Donald Trump.
