Minami Izu Area forms the southern tip of the peninsula. This is an area dominated by volcanic landforms created during the submarine phase of volcanism, going back millions of years.
The shore terrace of volcanic rocks and cross section of a dike (sheet rock) formation at Senjojiki and Mitsuishi Cape sites are major characetristic landscapes. The Nakagi geosite offers a great example of huge columnar joints, large tafoni (rocks with a honeycomb appearance) underlying volcaniclastic strata, and old volcanic ‘necks’ (magma passage of ancient submarine volcanoes)–forming a interesting mixture of landforms that hint at the dynamic activities that took place in geological time. At a place called Koura, you will come across 33 Buddhist deity figures sculpted out of volcanic rocks.
Several sea kayaking and boating tour options are available in this area.
