Demonstrators want constitution changed to impose presidential term limits that would bar president from running again.
Togo will delay presidential elections by 10 days to April 25, after the Economic Community of West African States (ECOWAS) said the voter list needed to be revised.
Opposition parties say the list includes thousands of people who have registered twice and are likely to vote for President Faure Gnassingbe.
In a statement read on national television by Communications Minister Koumealo Anate on Friday, the government said the move showed its “open-mindedness and its spirit of conciliation and desire for a peaceful election”.
There was no immediate comment from opposition or union leaders.
Gnassingbe is expected to win the vote and secure a third term in power. He was installed as president by the army in 2005 when his father died after leading the nation for 38 years.
Gnassingbe stepped down under international pressure but went on to win a hotly-contested election months later and was re-elected for a second term in 2010.
Attempts to introduce term limits have been blocked in parliament, where Gnassingbe’s party has a majority.
Late last year, opposition supporters took to the streets with civil society groups to demand reforms.
