Yoon bestowed a certificate of appointment on Han at the presidential office on Saturday morning. This comes 48 days after Han's nomination and eleven days after the new government took office.
According to a top office official, Yoon asked for Han's hard work and suggested they work diligently together.
The first item on Han's itinerary as prime minister is a visit to the Seoul National Cemetery in the afternoon.
On Sunday, he will chair meetings on economic strategy and COVID-19.
