The Uwa Sea washes the deeply indented southern coast of Ehime, a beautiful ria coastline of countless inlets, bays and small islands around Uwajima and the Nanyo region. Sheltered and rich in marine life, its calm waters are dotted with the rafts of pearl and fish farms — this is a major area for pearl cultivation and aquaculture — and backed by steep, citrus-clad hills. Sightseeing boats explore the scenery, weaving among the islands and past the coastal fishing villages, while the coast itself offers scenic drives, viewpoints and quiet beaches. Combined with Uwajima’s castle and food, the Uwa Sea makes the deep south of Ehime a rewarding, off-the-beaten-track destination of sea, islands and unhurried coastal life.
