In 1940, when Indonesia was colonized by the Japanese, the Zending Hospital's activities stopped, the hospital building was used for the needs of the Japanese army, such as ammunition storage and food storage by the Japanese occupiers. All health workers leave the hospital and return to their respective countries, the native health workers go to the forest. In 1940 – 1942 the Missionary Pastors were forced to leave Tapanuli, all Zending activities (Church, Education and Health) had to stop and the leadership of the Church shifted to the Indonesian Batak people, namely Ompui Pastor J. Sihombing.

In 1945, after Indonesia's independence, this hospital was reactivated by HKBP church pastors who were assisted by German missionaries, and Zending activities had begun to function and the hospital was called Doloksanggul HKBP Hospital where the head of this hospital was a nurse, Mr. Paian Samosir.

In 1960 the church handed over its management to the Government of the Republic of Indonesia c/q. Regent of North Tapanuli Regency. The government and the people of Doloksanggul jointly built and moved the location of the Hospital to its current location in Bonanionan Village to the north of the Doloksanggul HKBP church complex with the Hospital classification being Class D with a capacity of 30 beds, with the name Doloksanggul Help Hospital.
