Sorokdo

Prior to Japanese colonization, Sorokdo had a population of roughly 1000 people living in 170 households.[2]

Sorokdo is the site of the largest leper colony in South Korea, housed in Sorokdo National Hospital. The hospital was built in 1916, then known as Sorokdo Charity Clinic.[3] Established during the Japanese colonization of Korea, the hospital and the island were turned into a concentration camp for lepers, with a history of patient abuse including slave labor, forced sterilizations, unethical human experimentation, and deliberate starvation.[4] The Japanese authorities divided the island geographically - the eastern portion was a zone for non-patients, i.e. hospital staff and their families, while the western area was used to isolate patients. The dividing line between the two was referred to as sutanjang, meaning 'place of sadness'.[5] Patients were allowed to see their families once a month, but were forced to remain at a distance as the disease was believed to be airborne.

At its peak in 1940, 6,000 patients with Hansen's disease resided on the island.[6] Following the end of Japanese rule, the South Korean government continued to quarantine people with leprosy on Sorokdo until 1963.[7]

In 1962, two Catholic Austrian nurses, Margreth Pissarek and Marianne Stoeger, arrived at Sorokdo to provide treatment for patients and help establish community facilities, such as childcare centers.[8] They are both buried on the island in the patients' cemetery. In 1984 Pope John Paul II visited the island; this was considered a watershed moment in the consideration of the human rights of the remaining patients and residents.[2]

The Japanese colonial law regarding the quarantine of lepers remained in effect in South Korean until 1991; the South Korean government continued to send lepers to Sorokdo National Hospital and seven leper villages remained on the island as of 2007.

In 2009, the Sorokdo bridge opened, connecting the island to the mainland and the neighboring island of Geogeum.[3] Prior to the bridge's opening, formerly infected people were required to show permission from a doctor to take the ferry to leave the island. The Sorokdodo National Hospital predominantly treats patients with dementia, and the island sees roughly 300,000 tourists per year.

Sorokdo National Hospital Hansen’s Disease Museum was designated as a national specialized museum by the Ministry of Culture, Sports, and Tourism in 2019.

In 1935, Japanese authorities forced patients to build a Shinto shrine to mandate Shinto worship as part of the Japanese assimilationist policy naisen ittai (Japanese: 内鮮一体).[9] Still standing on the island, it is one of the last remaining Shinto shrines left in South Korea.[10] Other religious buildings, including Catholic and Protestant churches as well as Buddhist temples, have been built on the island.
