What is Chomonkyo|Gorge with Nationally Designated Scenic Beauty Representing Yamaguchi Prefecture
Chomonkyo is a gorge spanning Ato and Kawakmi, between Yamaguchi City and Hagi City in Yamaguchi Prefecture, located in the upper reaches of the Abu River. It is a deep valley carved by long-term erosion of quartz porphyry, characterized by varied landscapes including screen-like cliffs, odd-shaped rocks, waterfalls, and deep pools.
It was designated as a national scenic beauty in 1923 (Taisho 12) and was also designated as the Chomonkyo Prefectural Nature Park and a natural conservation area in Yamaguchi Prefecture in 1955 (Showa 30). The exploration trail (hiking trail) built along the Abu River extends approximately 5.5 kilometers and is enjoyed by many tourists as a hiking course where visitors can experience the gorge beauty up close.
Geography and Formation of Chomonkyo
Chomonkyo is a gorge formed in the middle reaches of the Abu River, which flows into the Sea of Japan. The mountain valley area including the main stream of the Abu River and its tributaries is called Chomonkyo, with a total length of approximately 12 kilometers. Geologically, hard quartz porphyry rock was carved by river erosion, and over many years, the present complex and beautiful terrain was formed.
Deep trees grow on both banks, and greenery spreads embracing the gorge. This rich natural environment serves as a habitat for diverse flora and fauna and is also known as a treasure trove of nature.
Four-Season Charm of Chomonkyo|Spectacular Views for Each Season
The greatest charm of Chomonkyo is the natural landscape that presents a different face in each of the four seasons. Whether you visit in spring, summer, fall, or winter, there are always new discoveries and moving experiences.
Spring|Cherry Blossoms and Budding Greenery
Chomonkyo welcomes a vibrant season with the blooming of cherry blossoms in spring. Cherry blossoms along the hiking trail color the gorge, creating a wonderful contrast with the clear Abu River. Cherry blossoms typically bloom from late March to early April, and this period attracts many cherry blossom viewers.
After the cherry blossoms fall, young leaves begin to sprout, and the entire gorge is enveloped in pale green. The young leaves season has fresh air and is ideal for hiking.
Summer|Deep Green and Cool Stream
Summer in Chomonkyo is a season of deep green covered in thick foliage. With trees densely leafed, the gorge interior is cool, and many people visit as a summer retreat. The murmuring of the Abu River sounds pleasant, and hiking while breathing in plenty of negative ions provides a refreshing experience separated from daily life.
Summer also brings abundant water volume, increasing the power of waterfalls and rapids. The cool air of the gorge and the sound of water will make you forget the heat.
Autumn|One of Yamaguchi Prefecture’s Premier Autumn Foliage Sites
Chomonkyo is busiest with tourists during the autumn foliage season. It is known as one of the most renowned autumn foliage sites in Yamaguchi Prefecture, reaching its peak typically from late October through mid-November.
Japanese maples, maples, and zelkova trees turn red and yellow, and the entire gorge is enveloped in a beauty like a brocade picture. In particular, the contrast between odd-shaped rocks and autumn foliage, and the reflection of autumn leaves in the clear stream are landscapes reminiscent of Japanese paintings. During the autumn foliage season, many photography enthusiasts and tourists from within and outside the prefecture visit to enjoy the beauty.
Winter|Serene Snowy Landscape
When snow falls, Chomonkyo in winter transforms into a serene landscape like ink painting. The snow-covered gorge sees few visitors and is a season to quietly face nature. You can enjoy winter-specific scenery such as frozen waterfalls, icicles, and snow-covered odd-shaped rocks.
In winter, the ground becomes slippery, so adequate equipment and caution are necessary when hiking. However, you can encounter a fantastical landscape completely different from other seasons.
