Security has been tightened throughout the country with police and military seen patrolling key urban areas ahead of anticipated anti-government protests scheduled for the nation's independence anniversary.
As of noon, however, no protests had materialized.
Residents in several major urban centers noted the day began with unusual quietness, with a large number opting to stay home due to doubts about whether protests would happen.
The demonstrations were called to call for political reforms following October's post-election unrest which left an unknown number of people dead.
Officials have conceded employing force against demonstrators, asserting that some groups were attempting to overthrow the regime.
On Tuesday, reporters observed nearly empty streets in the business hub, Dar es Salaam. This was a stark contrast to the city's typical weekday activity.
While quiet, a palpable tension filled the air.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while officers took up positions at key points, including around key public infrastructure.
On social media, activists and campaigners urged followers to remain vigilant, 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 where they were headed.
The government has not issued detailed comments on the heightened security measures or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests and cancelled independence day celebrations, advising the public to remain at home.
"The prevailing mood is one of quiet tension as people choose to stay home."
The day's events depicted a nation on edge, where the potential for demonstration led to a security clampdown in advance that left conspicuously quiet typically busy cities.
