A significant security presence has been deployed throughout the country with police and military seen patrolling major cities ahead of expected demonstrations against the government called to coincide with the nation's independence anniversary.
By midday, however, no demonstrations had begun.
Residents in several major urban centers noted the day began with unusual quietness, with many people choosing to remain indoors amid uncertainty over whether protests would happen.
The demonstrations were called to demand changes to the political system in the wake of the unrest that followed last October's elections which left an unknown number of people dead.
The authorities have admitted employing force against demonstrators, claiming that some groups were attempting to overthrow the regime.
On Tuesday, reporters observed nearly empty streets in the commercial capital, Dar es Salaam. This stood in sharp contrast to the city's usual weekday bustle.
While quiet, a palpable tension filled the air.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while officers took up positions at strategic locations, particularly near key public infrastructure.
On social media, activists and campaigners urged supporters to stay alert, implying that any protest activity would likely commence later in the day. This communication mirrored past mobilization efforts in the country, when participation grew as the day progressed.
Drivers who went out experienced regular stops at security checkpoints, where officers questioned drivers about where they were headed.
The government has not issued specific statements on the heightened security measures or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests and called off independence anniversary events, advising the public to remain at home.
"An eerie quiet masks the underlying tension felt by those indoors."
The overall situation painted a picture of a nation on edge, where the threat of protest led to a preemptive security lockdown that left conspicuously quiet typically busy cities.
