Lore & Background
The Sadamisaki Peninsula is extremely mountainous. Until the completion of national highway Route 197, traversing the peninsula by car was quite inconvenient. The Sadamisaki "Melody Line" on Route 197 is famous for the scattered cherry blossoms trees along the mountains. This combination of mountains and ocean make the area a popular sightseeing destination, especially in the spring when the sakura (cherry blossoms) are in bloom. Ferries run from Misaki Port at the tip of the peninsula to Saganoseki Port (Ōita). At the tip of the peninsula is Cape Sada, designated as a national park of the Seto Inland Sea. The lower region is designated as the Uwa Sea National Park land.
