Zaza is a sector in Rwanda to the east of Lake Mugesera and about 10 miles (16 km) west of Kibungo.

It is located in the Ngoma District of the Eastern Province of Rwanda.

The White Fathers founded a mission at Zaza in January 1902, where they taught the local people reading, writing and the gospel.

After several hundred had been baptized at Zara, Bishop John Joseph Hirth asked them to baptise fewer but of better quality.

[4] Zaza was the birthplace of Aloys Bigirumwami, the first Rwandan to become a bishop.
