Omogokei Gorge is one of the largest and most significant valleys in Shikoku, located at the southern foot of Mt. Ishizuchi in Kumakogen Town, Ehime Prefecture. As a nationally designated scenic spot, it is renowned for its untouched, pristine natural beauty. The most striking feature is the crystal-clear, emerald green stream surrounded by rugged cliffs and a series of beautiful waterfalls. It is a beloved destination for travelers seeking to escape the hustle and bustle of daily life and reconnect with the powerful energy of nature.
Situated at the foot of Mt. Ishizuchi, one of the highest peaks in Western Japan, this area has long been deeply connected to nature worship and the surrounding environment. The landscape of Omogokei is a masterpiece sculpted by the relentless flow of water and stone over countless years, a value recognized by its designation as a national scenic spot. This location is not merely a tourist destination but a vital part of the region's natural heritage.

There are two primary routes to enjoy the natural beauty of Omogokei from different perspectives. The first is the "Main Stream Route," which takes you through areas like Goshikogahara and Momiji-ga-hara, featuring powerful waterfalls like Tora-ga-taki. This route is characterized by its dynamic water flows and diverse terrain. The second is the "Teppoishi-gawa Route," which offers a more serene and tranquil atmosphere. This path is ideal for those seeking a peaceful stroll along the river. Because the colors of the water and the surrounding vegetation change with the seasons, every visit offers a unique and fresh experience.
While Omogokei is beautiful year-round, the most recommended times to visit are spring, summer, and autumn. In spring, you can witness the vibrant new greenery forming lush tunnels of life. In summer, the cool river breeze and shaded groves make it an ideal retreat from the heat. The most spectacular season, however, is autumn. From late October to early November, the surrounding trees turn brilliant shades of yellow, orange, and red, creating a stunning contrast against the emerald green water. This seasonal transformation is truly a sight to behold.

Activities here primarily focus on hiking and nature walks. As you walk along the well-maintained paths, you can listen to the soothing sound of the flowing water and breathe in the crisp, clean air to refresh both mind and body. The area is also a paradise for photographers, with numerous photogenic spots featuring waterfalls, rocky cliffs, and seasonal colors. Taking the time to observe the clarity of the water and the unique rock formations is a truly luxurious way to spend your time.
The drive toward Omogokei, such as via the Ishizuchi Skyline, offers grand views of the majestic nature through your car window. The surrounding Kumakogen Town is also rich in natural attractions, including various camping sites, hiking trails, and hot spring (onsen) facilities. Enjoying local specialties, such as citrus fruits or dishes made with local ingredients, is another wonderful way to experience the region's charm.
Since this is a natural gorge, comfortable clothing and sturdy shoes (such as sneakers or trekking shoes) are essential. Paths can be wet or rocky, so non-slip footwear is highly recommended.
