Church spokesman Ahn Ho-yeul says church leader Hyung-jin Moon plans to receive mourners at a church-owned peace institute in Pyongyang.
The church has business interests in North Korea, and the elder Moon worked to build ties with North Korean leaders.
Ahn said Friday that Moon was traveling with the president of North Korea-based Pyeonghwa Motors. The company is partially owned by the church.
North Korean leader Kim Jong Un offered his condolences on Moon's death earlier this week.
Moon, a self-proclaimed messiah, died Monday at the age of 92 in Gapyeong County, northeast of Seoul. His funeral is Sept. 15.
