Security has been tightened throughout the country with police and military seen patrolling major cities in anticipation of expected anti-government protests scheduled for independence day.
By midday, however, no demonstrations had begun.
People living in Dar es Salaam, Arusha, Mbeya, Mwanza noted the day began with unusual quietness, with a large number opting to stay home amid uncertainty over if the demonstrations would proceed.
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 using force against protesters, asserting that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday streets that were largely deserted in the commercial capital, Dar es Salaam. This stood in sharp contrast to the city's usual weekday bustle.
Although quiet, the atmosphere remained tense.
Security vehicles were seen driving along primary thoroughfares and junctions, while officers took up positions at strategic locations, including around important public buildings and facilities.
Through online platforms, organizers advised supporters to stay alert, suggesting any demonstrations were unlikely to begin until the afternoon. This communication mirrored previous protest calls in Tanzania, when turnout increased later in the day.
Drivers who went out experienced regular stops at security checkpoints, where police interrogated motorists about where they were headed.
The government has not issued specific statements on the heightened security measures or on the planned protests.
The government has prohibited the intended demonstrations 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 depicted a country under strain, where the threat of protest resulted in a security clampdown in advance that effectively emptied normally bustling cities.
