Izu-Tobu Travel Guide

The Izu-Tobu volcano group, also known as the Higashi-Izu volcano group, is a fascinating geological area on the eastern side of the Izu Peninsula. This expansive volcanic field, covering over 400 square kilometers, showcases a diverse landscape formed by both ancient stratovolcanoes and more recent monogenetic volcanoes. Over the last 140,000 years, approximately 70 subaerial monogenetic volcanoes have emerged, alongside similar submarine cones dotting the offshore area.Izu-Tobu's volcanic activity has played a significant role in shaping the peninsula's landscape. Lava flows have created unique coastal formations like the Jōgasaki Coast and Jōren Falls, while pyroclastic flows have left their mark across the region. The most recent activity occurred in 1989, with a small submarine eruption. Although Izu-Tobu is largely dormant, the area experiences frequent earthquake swarms, a reminder of the underlying tectonic forces at play.Today, Izu-Tobu attracts visitors with its natural beauty and geological significance. The area offers hiking trails, panoramic views, and hot springs, with the volcanic terrain providing a unique backdrop for exploration and relaxation. Nearby attractions include Mount Omuro, a well-preserved scoria cone accessible by cable car, and the Jogasaki Coast, known for its dramatic cliffs and the Kadowaki Suspension Bridge.
