A significant security presence has been deployed throughout the country with officers and soldiers observed on patrol in key urban areas ahead 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 whether protests would happen.
The demonstrations were called to call for changes to the political system following October's post-election unrest which left an unknown number of people dead.
Officials have conceded using force against protesters, claiming that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday streets that were largely deserted in the business hub, Dar es Salaam. This was a stark contrast to the city's typical weekday activity.
The quiet was undercut by a persistent sense of tension.
Security vehicles were seen driving along primary thoroughfares and junctions, while personnel were stationed at key points, particularly near important public buildings and facilities.
On social media, activists and campaigners urged followers to remain vigilant, suggesting any demonstrations were unlikely to begin until the afternoon. The messaging echoed previous protest calls in Tanzania, when participation grew as the day progressed.
Motorists who ventured out reported regular stops at security checkpoints, where police interrogated motorists about where they were headed.
Authorities have not provided specific statements on the increased security or on the scheduled demonstrations.
The government has prohibited the intended demonstrations and cancelled independence day celebrations, urging citizens to stay indoors.
"With many staying at home the atmosphere is quiet but tense."
The day's events depicted a country under strain, where the threat of protest resulted in a preemptive security lockdown that left conspicuously quiet typically busy cities.
