Mount Daisen was historically revered as a sacred mountain, restricted to ascetic monks and closed to the general public until the late 19th century.
The Oki Islands were formed by two distinct volcanic stages, resulting in a combination of alkaline and tholeiitic rock formations.
The beech forests on the northern slopes of Mount Daisen are some of the largest remaining primary beech stands in western Japan.
The park's territory is fragmented, connecting mainland mountainous volcanic terrain with remote island environments across the Sea of Japan.
Izumo Taisha, located within the park's boundaries, contains the tallest wooden shrine building in Japan at approximately 24 meters high.
Daisen-Oki National Park spans three distinct regions across Tottori, Shimane, and Okayama prefectures, encompassing the volcanic Mount Daisen, the Oki Islands, and the Shimane Peninsula. Mount Daisen, the park's centerpiece, is a prominent stratovolcano serving as the highest peak in the Chugoku region. The park preserves diverse ecosystems ranging from alpine flora on Daisen's slopes to unique maritime landscapes in the Oki Islands archipelago. The Oki Islands are a designated UNESCO Global Geopark due to their unique geological history involving volcanic formation and subsequent erosion. The park also includes significant cultural sites, most notably Izumo Taisha, one of Japan's oldest and most historically significant Shinto shrines. Visitors can traverse extensive hiking trails that connect volcanic craters to coastal cliffs and ancient forest paths. The landscape facilitates high biodiversity, supporting various protected bird species and rare plant life. It is managed by the Japanese Ministry of the Environment as a protected nature preserve.

Prioritize visiting the Daisen-ji Temple area for well-maintained trailheads leading to the summit.
Rent a vehicle to navigate between the dispersed regions, as public transit is limited in the more rural mountainous zones.
Bring specialized hiking gear including sturdy boots, as the terrain on Mount Daisen is prone to erosion and can be slippery.
Attempting to hike to the summit of Mount Daisen during winter months without professional mountaineering experience and equipment.
Trail access to the highest summit points may be restricted during periods of heavy snowfall or severe weather.
Stay on marked trails to protect sensitive alpine vegetation and follow 'leave no trace' principles.
