The Unification Ministry says that the number of South Korean tourists to Gaeseong in North Korea will top 100-thousand Wednesday.

The head of Hyundai Asan, the South Korean operator of tours to Gaeseong, will visit the North's border city to mark the milestone.

The Hyundai Asan chief and his party will hold a celebration at the inter-Korean immigration office at Dorasan train station and cross the border along with tourists.
