Several pictures published on the front page of the state-run Rodong Sinmun newspaper on Tuesday showed Kim smiling and gesturing on a visit to a housing development in Pyongyang, although there was no indication which day the event took place.
Surrounded by aides and wearing his signature dark buttoned suit, Kim Jong Un appeared to be supporting himself with a black walking stick.
Before Tuesday, there had been no official reports on the 31-year-old Kim appearing in public since he attended a concert with his wife on Sept. 3. He missed an important political anniversary on Friday as well as a recent session of the country's parliament.
A story in the official KCNA news agency did not mention Kim's health or lengthy absence from public view. It said he "gave field guidance" to the new Wisong Scientists Residential District and visited the newly built Natural Energy Institute of the State Academy of Sciences.
In still pictures broadcast by state TV, Kim was often shown seated, once with a cigarette in his hand, while his aides stood.
