Merkel's visit, along with German Defense Minister Thomas de Maiziere, comes less than a week after a German soldier died in an insurgent attack in northern Afghanistan, Voice of America reported.
Early Friday, Merkel and de Maiziere visited Mazar-i-Sharif city, then made their way to Kunduz, about 150 miles north of Kabul, Chinese news service Xinhua reported.
There are approximately 4,200 Germans in the NATO International Security Assistance Force, the third-largest international troop deployment in Afghanistan.
Germany will station 600 to 800 soldiers in Afghanistan in the course of two years beginning in 2015 after NATO operations end, de Maiziere said last month.
