Izu Peninsula
The Izu Peninsula juts into the Pacific like a clenched fist of volcanic rock, its coastline slashed by cliffs, sea caves, and hidden coves that plunge straight into some of the deepest blue water in Japan. Dozens of hot spring towns are scattered across its mountains and shores, fed by geothermal waters that burst from the earth in the most dramatic ocean-facing settings imaginable. From the wild black sand beaches of the west coast to the coral reefs of the south, Izu rewards travellers who venture beyond the famous onsen towns.
