Obara Gorge (Hekigyoku Gorge) Complete Guide | Autumn Foliage Destination and Four-Season Charm in Shiraishi City, Miyagi Prefecture
What is Obara Gorge (Hekigyoku Gorge)?
Obara Gorge is a beautiful gorge spanning approximately 4 kilometers located in the upper reaches of the Shiraishi River flowing through the western part of Shiraishi City in Miyagi Prefecture. Also known by the elegant name Hekigyoku Gorge (碧玉渓), this gorge was named by Tokutomi Soho (徳富蘇峰), a renowned critic from the Meiji era.
In 1938 (Showa 13), when Tokutomi Soho visited this area, he was deeply impressed by the beautiful turquoise-hued stream in the gorge and the natural scenery surrounding it, and composed the name “Hekigyoku Gorge.” The term “hekigyoku” refers to blue or green gemstones, perfectly symbolizing the gorge’s beauty.
Approximately 10 minutes from Shiraishi city center on National Route 113 heading toward Obara, a deep V-shaped gorge appears continuing along the highway. Located near the Obara Hot Spring area, this gorge is known for its spectacular views created by nature’s seasonal changes, and has become a representative autumn foliage spot in Miyagi Prefecture, attracting many tourists from both within and outside the city, especially during the autumn leaves season.

Nature and Geology of Obara Gorge
Gorge Formation Process
Obara Gorge is a V-shaped valley formed by the Shiraishi River’s long-term erosion of bedrock. The underlying bedrock in this region consists primarily of volcanic and sedimentary rock, with the river’s flow carving out the hard bedrock, creating the deep gorge.
The turquoise water in the gorge results from mineral components dissolved from the bedrock and the water’s high transparency. This beautiful turquoise color is why Tokutomi Soho named it “Hekigyoku Gorge.”
Vegetation of the Gorge
The vegetation around Obara Gorge centers on cool-temperate deciduous broadleaf forest. Deciduous trees including oak, hackberry, Japanese maple, and other varieties dominate, creating beautiful autumn foliage each fall.
Along the stream, plants preferring moist environments are observed, and mountain wildflowers bloom splendidly in spring. On the gorge’s rock faces, abundant mosses create landscape like green carpeting.
Waterfalls in the Gorge
Several waterfalls dot Obara Gorge. While not large in scale, these waterfalls constitute important elements of the gorge’s beauty. Walking the trail, you can hear the waterfall sounds in certain locations, enjoying the experience while feeling negative ions.
