On August 31, the Korea National Park Service, under the Ministry of Environment, announced that it will be signing a business agreement with AStory to produce the series. AStory is the drama production company behind the hit shows Signal and Kingdom (two seasons).
Jirisan, set against the backdrop of the titular mountain, is described as a mystery-thriller series that will center on the rescue of distressed visitors and the activities of the park rangers.
According to the agreement, the Korea National Park Service and AStory will jointly promote the drama. The former will help in finding shooting locations and writing the script, while the latter will assist in the development of products related to the park and the drama, as well as attract attention to the filming site.
Kwon Kyeong-up, the chairman of the Korea National Park Service, shared, “This is the first drama to be filmed against the backdrop of Jirisan, the first national park in Korea, so it is very meaningful. I look forward to [being able to] raise awareness.”
Jirisan is a collaborative work between a power duo—screenwriter Kim Eun-hee of Signal (2016) and Kingdom (Seasons 1 & 2/2019, 2020) and director Lee Eung-bok of Descendants of the Sun (2016), Guardian: The Lonely and Great God (2016–2017), and Mr. Sunshine (2018). As of writing, the broadcasting network and airing date of Jirisan (also Mount Jiri) are still under discussion.
