Kawazu Higashiizu area is an ideal location to see overlapping layers of old and comparatively new volcanic depositions and well as landscapes created by flowing water.
the 7 waterfalls of Kawazu is probably the most famous tourist attraction in this area. These waterfalls line up on a relatively short stretch of river valley formed by the Kawazu river that flows over a layer of lava that spilled into an older gorge. Spectacular columnar joints are also visible on the rocks. The area was made famous by the Nobel prize winning novelist Kawabata Yasunari, who featured it as a backdrop for his celebrated novel: The Dancing Girl of Izu. The valley is cool in summer and is set ablaze by autumnal colors on the trees. Kawazu Town is also famous for the deep pink Kawazu Sakura flowers that bloom along the riverside in February-March.
The Anagiri Coast is an interesting location where you can see eroded sea caves and lava rocks that were erupted during the activity of the Amagi chain (800,000-200,000 years ago). Anagiri forms an outer rim of this deposition, coastline to its north is dominated by volcanic products of the more recent Izu Tobu Monogenetic chain.
A characteristic monogenetic volcano deposition can be seen at the Inatori Geosite. Here you can see the cross section of the Inatori volcano. This site is used for education but there is no well preserved trails.
The Shiranuta Pond located at the upstream Kawakubo River basin is a large cavity formed by erosion induced landslide in the Amagi Range. The beautiful blue-green waters of the pond form the habitat for the green tree frog.
The Hosono Marsh is another major attraction of this area. Formed due to the presence of a non-porous volcanic deposition that prevents water to seep inside the ground, this marsh is full of wetland flowers in summer and early autumn. In autumn, the pampas grassland in the Hosono Plateau becomes a golden sea of waving grass.
