Omogo Valley (Kumakogen Town, Ehime Prefecture)

Overview (history, characteristics, attractions)

Omogokei is a scenic spot where you can enjoy the beauty of the valley carved by the Omogogawa River, which flows through Kumakogen Town, Ehime Prefecture. The clear streams flowing from the mountains of the Ishizuchi mountain range have eroded the granite and bedrock, creating a series of strangely shaped rocks, pools, and waterfalls, creating a deep V-shaped valley with crystal clear water. A favorite among locals since ancient times, the valley is attractive for its changing seasonal appearance. The vibrant colors of the new greenery and autumn leaves are particularly popular, attracting many photography enthusiasts and hikers.

Highlights

• Valley Promenade: There are promenades where you can enjoy different scenery at each section, and they are suitable for everything from easy strolls to serious hikes.
• Clear streams and pools (emerald green water surface): After rain or when the snow melts, the water volume increases, making the deep pools and streams look even more vibrant.
• Strange rocks and cliffs: The unique rock formations and pillar-shaped rocks formed by weathering of granite are scattered throughout the area, allowing you to enjoy the beauty of their shapes.
• Waterfalls and changing currents: There are a succession of large and small waterfalls, rapids, and calm pools, and the river looks different in each location.
• The colors of the four seasons: the fresh greenery of spring, the deep green of early summer, and the autumn leaves are particularly spectacular, and there are many spots for taking photos.

Access (nearest station, transportation, etc.)

• The nearest major bases are Matsuyama Station (JR) and Matsuyama Airport. Kumakogen Town is generally accessed from the Matsuyama area.
• By car: Approximately 1-1.5 hours from central Matsuyama via national and prefectural roads (depending on road conditions). As the area is in a mountainous area, it is most convenient to travel by car. Parking lots are often available near the entrance to the valley, but there are limited spaces available, so we recommend arriving early during peak seasons.
• Public transportation: Local buses and municipal buses may operate, but please check the timetable in advance as they are infrequent. If using public transportation, you may also need to take a taxi from the nearest bus stop.
• Note: Mobile phone reception can be unstable in some mountainous areas. For access details (bus times, parking availability, etc.), please check the latest information at the Kumakogen Town Tourism Association or their official website.

Estimated stay (estimated time required)

• Easy walk: Approximately 1-2 hours if you only want to see the main sights of the valley.
• A leisurely stroll and photography: 2 to 4 hours, including photography and breaks.
• Hiking and exploring the area: Half a day to a full day is recommended if you want to hike the surrounding hiking trails or go further upstream (plan accordingly depending on your equipment and stamina).

Nearby spots

• Mount Ishizuchi (Ishizuchi mountain range): The trailhead and viewpoints for Mount Ishizuchi, the highest peak in Shikoku, are relatively close, making it a great place to combine a mountain trip.
• Kumakogen Town's streetscape and roadside station: There are facilities where you can taste local specialties and meals.
• Nearby hot springs: There are hot spring facilities scattered throughout the mountainous area that offer day trips, so you can enjoy a soak after a walk.

Things to be aware of (crowds, manners, seasonal precautions, etc.)

• Crowds: The park is crowded during the autumn foliage season, holidays, and weekends, and the parking lot tends to fill up quickly. We recommend leaving early in the morning during peak seasons.
• Safety precautions: The rocky areas in the gorge can be very slippery and dangerous when wet. Wear non-slip shoes and avoid wading in the river or treacherous slopes.
• Weather changes: The weather in mountainous areas is prone to change, and sudden rain can cause flooding. Please check the weather forecast in advance, and avoid entering the valley when the water level is high.
• Nature Conservation and Manners: Please be considerate of the surrounding nature and other users by always taking your trash with you, not stepping on vegetation, and not shouting.
• Mobile phones/contact information: Mobile phone signals may be weak in some areas. If you are traveling alone or hiking long distances, it is a good idea to let your family know your plans in advance.
• Check access information: Please note that the operating status of bus routes, parking lots, and facilities may change, so please check official information from the Kumakogen Town Tourism Association in advance.
