Security has been tightened throughout the country with police and military seen patrolling major cities in anticipation of anticipated demonstrations against the government called to coincide with independence day.
As of noon, however, no protests had materialized.
Residents in several major urban centers reported an unusually slow start to the day, with a large number opting to stay home due to doubts about whether protests would happen.
The demonstrations were called to demand changes to the political system following October's post-election unrest which resulted in an unconfirmed death toll.
The authorities have admitted using force against protesters, asserting that some groups were attempting to overthrow the regime.
On Tuesday, reporters observed streets that were largely deserted in the commercial capital, Dar es Salaam. This was a stark contrast to the city's usual weekday bustle.
The quiet was undercut by a persistent sense of tension.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while personnel were stationed at key points, including around key public infrastructure.
Through online platforms, organizers advised supporters to stay alert, implying that any protest activity would likely commence later in the day. The messaging echoed previous protest calls in Tanzania, when turnout increased later in the day.
Motorists who ventured out reported frequent checks at roadblocks, where officers questioned drivers about their destinations.
Authorities have not provided detailed comments on the increased security or on the planned protests.
Tanzanian authorities have banned the intended demonstrations and called off independence anniversary events, urging citizens to stay indoors.
"With many staying at home the atmosphere is quiet but tense."
The overall situation painted a picture of a nation on edge, where the threat of protest led to a security clampdown in advance that effectively emptied normally bustling cities.
