During their three-day visit, the North Korean officials will meet with South Korean President Moon Jae-in, who is trying to use the Olympics as an opportunity to pull North Korea into meaningful talks over its nuclear programme.
The delegates briefly met a group of South Korean officials on Friday, including Unification Minister Cho Myoung-gyon, who greeted them at the airport, according to the ministry.
They were later scheduled to board a high-speed train to Pyeongchang.
