The park's marine and terrestrial environments support a rich diversity of wildlife. The coastal waters host various fish species, while tidal pools contain numerous invertebrates including crabs, sea stars, and anemones. Seabirds such as black-tailed gulls and cormorants are common sights along the coast. The inland areas provide habitat for smaller mammals, numerous bird species, and various insects, including several endemic species.
The diverse vegetation of Sanin Kaigan includes coastal pine forests, particularly Japanese black pine (Pinus thunbergii), which helps stabilize the sand dunes. The park's varied topography supports different plant communities, from hardy coastal species adapted to salt spray and strong winds to more delicate inland flora. Spring brings vibrant wildflower displays, while autumn sees dramatic color changes in the deciduous forests.
The park's dramatic coastline showcases remarkable geological features formed by volcanic activity and marine erosion over millions of years. Notable formations include the Tottori Sand Dunes, Japan's largest coastal dunes, and numerous sea caves, arches, and pillars carved by wave action. The coastline's unique ria formation, where former river valleys were flooded by rising sea levels, creates a deeply indented shoreline characteristic of the region.
Established as a national park in 1963, Sanin Kaigan's coastline has been shaped by centuries of human activity and natural forces. The region has historically served as an important maritime route, with numerous fishing villages and ports developing along its shores. Ancient legends and folklore, particularly those related to the Shinto religion, are deeply connected to many of the park's distinctive rock formations and caves, reflecting the area's rich cultural heritage.
Key attractions include the massive Tottori Sand Dunes, stretching over 30 square kilometers, the uniquely shaped Uradome Coast with its weathered cliffs and caves, and the scenic Kasumi Coast featuring dramatic rock formations. The park also encompasses several islands, including Natanejima, known for its distinctive geological formations and breeding seabird colonies. Visitors can enjoy activities ranging from sand boarding and camel rides on the dunes to coastal hiking and sea kayaking.
The Sanin Kaigan region experiences a humid subtropical climate with significant seasonal variations. Winters are cool and bring heavy snowfall, particularly in January and February, while summers are warm and humid with temperatures reaching around 30°C (86°F). The area receives substantial rainfall throughout the year, with June being the wettest month during the rainy season.
