Ogi Peninsula Round Trip Route

Approximately 13 million years ago, large-scale volcanic activity occurred on the floor of the Japan Sea. The black lava that erupted during this time formed the land of the Ogi Peninsula. The unique landscape created by uplift and the erosion of the peninsula has been designated a national natural monument and a place of scenic beauty. Enjoy this magnificent scenic landscape. Wear comfortable shoes and clothing when walking on the coast because rocks are exposed in many places.

Are you ready to start your trip to the Ogi Peninsula? Let’s get started!


Legendary island connected by a red bridge

Yajima was named as such because people of the area harvest high quality bamboo to make arrows (“ya” means arrow and “jima” means island in Japanese). As for Kyojima, its name came from the story of a disciple of Nichiren. The disciple, named Nichiro, was carrying a letter to release Nichiren when he was caught in a storm and drifted ashore to the island, where he spent the night.

※ The island is currently inaccessible due to shoreline erosion.

Undersea volcanic land created by earthquakes and waves

2Shukunegi Coast

Are we on Mars? Explore the landscape of this reddish-brown uplifted wave-cut platform

Approximately 13 to 14 million years ago, submarine volcanoes were active on the Ogi Peninsula. The Shukunegi Coast was formed by stones and volcanic ash ejected from the deep undersea volcanoes. This volcanic activity uplifted the land, creating the landforms we see today.

3Chojagabashi Bridge

Walk 40m above sea level

The bridge was built 40 meters above the cove of Fukaura. From the bridge, you can see the cobalt blue sea, the coastline formed by the uplift of black lava from the seafloor, and the terraced rice field landforms.

Sawasaki Lighthouse and Takenoko iwa Rock

This lighthouse is located at the westernmost tip of Sado Island. The flat Sawasaki coast is part of the scenic Sado Ogi Coast. It is made of lava, evidence of undersea volcanic activity. Takenoko Iwa, bamboo shoot rocks, can also be found here. Please keep a certain distance from the cliffs because there is a risk of rock fall.

5Miko iwa Rock

Black rocky mountain with well-developed columnar joints

Many olive colored peridots can be found in this rock.

Miko iwa Rock was formed when magma slowly cooled and hardened in the strata of the seafloor, and became shaped like pillars (columnar joints). This rock is scattered with olive-colored mineral called olivine.

Rare basalt similar to the rock found in Hawaii

6Kuguri iwa Rock

Are those giraffes appearing on a vast uplifted wave-cut platform?

This rock was formed when lava flowed to the seafloor due to undersea volcanic activity long ago, cooled, and hardened. New, hot lava was repeatedly piled on top of the cooled lava, and this process was repeated. It is also called “giraffe iwa rock” because of its white cloud-shaped pattern that makes it look like a giraffe.
