Cape Irozaki
Cape Irozaki (石廊崎, Irōzaki) lies along the southern coastline of the Izu Peninsula at the peninsula’s southernmost tip. The Irozaki lighthouse and Iro Shrine can be found at the cape; the shrine is built into the rocks at the very tip of the cape and offers beautiful views of the craggy coast.
The coast around Cape Irozaki is rugged and relatively unspoiled, and can be viewed from sightseeing cruises which last about 25 minutes. There are also other nice capes along the southern coastline with rocky shorelines, craggy terrain and some of the Izu Peninsula’s best beaches.
Dogashima
Dogashima (堂ヶ島, Dōgashima) in western Izu is famous for its dramatic stone formations, cliffs and caves formed by the lava flow of past volcanic eruptions and shoreline erosion. The best way to see the coast is from one of the frequently departing sightseeing boats, which briefly enter one of the larger caves. The cruises around Dogashima take about 20-25 minutes, although longer tours are also available.
On the small peninsula south of the boat pier is the Sawada Park Open Air Bath (Sawada Koen Rotemburo), a cliff-side hot spring bath with beautiful views over the ocean. The bath is gender-separated, closed on Tuesdays (next day if Tuesday is a national holiday) and costs 600 yen admission.
The Futo Coast, about 2.5 kilometers northwest of Dogashima, is a small bay with a stony beach and a hiking trail that leads to rock formations known as magmatic dikes. These dikes were formed when magma rose to the surface and solidified along the vent of a volcano. The outer layers of the volcano eroded over time, leaving just the volcanic neck – a magmatic dike.
