Complete Guide to Namegazawa Gorge (Shizuoka Prefecture) | Touring the Spectacular Single Rock and Literary Landmarks of Yasushi Inoue
Namegazawa Gorge (滑沢渓谷), located in Izu City, Shizuoka Prefecture, is a mystical gorge wrapped in deep primeval forest that spreads to the north of Amagi Pass. Certified as a Geosite of the Izu Peninsula Geopark, it captivates visitors with its unique topography formed by volcanic activity and the flow of clear water.
Charm and Characteristics of Namegazawa Gorge
Spectacular Single Rock Landscape of Izu’s Largest Scale
The main attraction of Namegazawa Gorge is a massive andesite single rock stretching approximately 500 meters in length. This rock is formed from lava flows that erupted from Namegazawa Volcano (one of the Izu East Volcanic Group) tens of thousands of years ago, and is characterized by columnar jointing formed during the cooling process of volcanic magma.
The sight of clear water flowing down the smooth, polished rock surface like a white cloth is truly a work of art created by nature over long ages. The landscape continues with varied scenery—rushing water becoming white ribbons or forming deep pools—offering visitors inexhaustible natural beauty.
Setting for Yasushi Inoue’s “Hunting Gun”
Namegazawa Gorge is also known as the setting for “Hunting Gun,” the debut novel of literary master Yasushi Inoue. Inoue overlapped the emotional state of a solitary man with the scenery of this gorge in the opening of his work.
A literary monument to Yasushi Inoue stands near the gorge entrance, making it a worthwhile destination for literature enthusiasts. The quiet space enclosed by cold rock surfaces and deep forest is a precious place where one can experience the world of the novel.
Geosite of the Izu Peninsula Geopark
Namegazawa Gorge is certified as a Geosite of the Izu Peninsula Geopark, holding significant geological value. As valuable topography that tells the history of volcanic activity on the Izu Peninsula, it is noted from an educational perspective as well.

Geological Value of Namegazawa Gorge
Izu East Volcanic Group and Lava Flow
The single rock forming Namegazawa Gorge is composed of lava flows from Namegazawa Volcano, which was active tens of thousands of years ago, that cooled and solidified. The Izu East Volcanic Group played an important role in the geological formation of the Izu Peninsula, and the lava flow from Namegazawa Volcano, as one part of it, is a valuable geological heritage that conveys the state of volcanic activity at that time.
Formation Process of Columnar Jointing
The columnar jointing observable at Namegazawa Gorge is formed by contraction during magma cooling, creating regular cracks (joints). This geological feature serves as an important clue to understanding volcanic activity and cooling processes, and is highly valued for its educational significance.
Erosion by Water
Over long ages, clear water has carved away the andesite bedrock and polished it smoothly. Through this water erosion, the beautiful smooth rock surface visible today has been formed. As an artwork created by the forces of nature, it is a place of high value both geologically and aesthetically.
