Umegase Valley is a beautiful gorge located in Ichihara City, Chiba Prefecture. Formed through erosion by the Umegase River, a tributary of the Yoro River, the valley is surrounded by rich natural scenery and is particularly famous for its spectacular autumn foliage.
The valley lies close to the well-known Yoro Valley and is a popular destination for hiking and nature walks. Visitors can enjoy seasonal scenery while following trails along the river, discovering dramatic cliffs, forests, historic sites, and mountain viewpoints along the way.
Umegase Valley is especially appealing because it combines the beauty of the natural landscape with the history of people who once sought to create an ideal place to live among the mountains.
Umegase Valley is located near the southern end of Ichihara City. The Umegase River originates approximately 500 meters south of Mount Daifuku, the highest mountain in Ichihara City, with an elevation of 292 meters.
The river flows through the valley before joining the main stream of the Yoro River approximately 300 meters southwest of Yoro Valley Station on the Kominato Railway.
The surrounding hills and forests create a peaceful natural environment that changes dramatically with the seasons. Spring and summer bring fresh greenery, while autumn transforms the valley into a colorful landscape of red, orange, and yellow leaves.
One of the most distinctive geological features of the valley is the series of steep erosion cliffs known as the Umegase Formation.
Along sections of the river, which is approximately 4 to 5 meters wide, vertical cliffs rise dramatically on both sides. In some areas, these cliffs extend for approximately 80 meters and reach heights of 30 to 50 meters.
The contrast between the narrow river, towering cliffs, and surrounding forest creates one of the most striking landscapes in the Yoro Valley area.
Deep inside the valley lies the site known as the Former Residence of Makoto Hidaka. Hidaka was an educator during the Meiji Period who dreamed of creating an ideal rural retreat in this area.
Inspired by Tsukigase in Nara, an area historically famous for its plum blossoms, he named the area “Umegase,” combining the Japanese words associated with plums and a valley.
Hidaka built a residence in the valley and planted maple trees around the property. Although he passed away before fully realizing his vision, some of the large maple trees around the former residence remain today as reminders of his efforts.
The site provides an interesting historical dimension to the valley, showing how the natural landscape inspired people to imagine an ideal place surrounded by forests and mountains.
Umegase Valley is a popular hiking destination. A trail runs along the river from Megakura to the Former Residence of Makoto Hidaka. Along this route, hikers can cross parts of the stream using stepping stones and enjoy the scenery at close range.
Another trail runs from the foot of Mount Daifuku to the former residence, climbing along the ridge through an area known as Momiji-dani. This route includes relatively steep sections, so hikers should use appropriate footwear and take care when walking.
The Former Residence of Makoto Hidaka, also known as the Former Hidaka Residence or the Site of Hidaka’s Residence, is one of the valley’s most interesting historical landmarks.
During the autumn foliage season, large maple trees around the site turn brilliant shades of red and orange. The combination of the trees, mountain landscape, and traces of the former residence evokes Hidaka’s vision of an ideal retreat in nature.
Momiji-dani, literally meaning “Maple Valley,” is one of the most scenic areas in Umegase Valley during autumn.
As the leaves change color, the valley becomes covered in vivid shades of red, orange, and yellow. The combination of colorful foliage, forest trails, and mountain scenery makes this area particularly attractive for autumn hiking and photography.
The Mount Daifuku Observatory is located near the summit of Mount Daifuku, which stands at 292 meters above sea level.
From the viewpoint, visitors can enjoy broad views over Yoro Valley and the surrounding mountains. The scenery is particularly impressive during the autumn foliage season, when the surrounding hills are covered in vibrant colors.
Shiratori Shrine stands at the summit of Mount Daifuku and is dedicated to Yamato Takeru, a legendary figure in Japanese mythology.
Surrounded by forest and away from the bustle of urban areas, the shrine provides a quiet place to pause during a mountain walk. Its location also gives visitors a chance to experience the connection between traditional Japanese spirituality and the natural landscape.
Umegase Chaya is a small rest stop where hikers can take a break during their walk. Visitors can enjoy local dishes and light refreshments while surrounded by the natural scenery of the valley.
For those spending several hours hiking in the area, the tea house provides a convenient opportunity to rest and enjoy a taste of local food.
Located near the valley, the Shibata Museum of Art offers a different type of experience. The museum is open on Saturdays and Sundays and displays various works of art and historical materials.
A visit can be combined with a walk through Umegase Valley for travelers interested in experiencing both the natural and cultural attractions of the area.
Umegase Valley is particularly well known for its autumn foliage. As the maple and other trees change color, the cliffs and forests surrounding the river are transformed into a spectacular seasonal landscape.
Autumn is also an excellent time for hiking, as visitors can enjoy the colorful scenery while following the riverside trails and mountain paths.
The valley has a different atmosphere during spring and summer. Fresh green leaves cover the surrounding forests, and the sound of flowing water creates a peaceful environment.
Visitors interested in hiking and nature photography can therefore enjoy the valley beyond the autumn season as well.
The nearest station is Yoro Valley Station on the Kominato Railway. From the station, it takes approximately 90 minutes on foot to reach the valley.
During the autumn foliage season, a shuttle bus to the Umegase Valley entrance operates on weekends and public holidays. This can be a convenient option for visitors who want to reduce the amount of walking from the station.
From the Kisarazu-Higashi Interchange on the Ken-O Expressway, take National Route 410 south toward Kururi. Turn left at the Kururi intersection and follow Chiba Prefectural Route 32 toward Otaki and Kimitsu.
Near Ishigami in Ichihara City, turn onto Chiba Prefectural Route 81, the Ichihara-Amatsu-Kominato Line, and continue toward Yoro Valley.
From the Ichihara Interchange on the Tateyama Expressway, take National Route 297 south toward Kofūdai. Turn right at the Yonezawa intersection and follow Chiba Prefectural Route 81, also known as the Kiyosumi-Yoro Line, toward Yoro Valley and Umegase Valley.
Some of the trails follow the river and require visitors to cross streams using stepping stones. After rain, rocks and paths may become slippery, so sturdy shoes with good grip are recommended.
The route climbing from the foot of Mount Daifuku toward the former residence also includes steep sections. Visitors should allow enough time and choose a route appropriate for their fitness level.
Umegase Valley is a scenic destination where dramatic geological formations, colorful forests, mountain trails, and local history come together. Its steep Umegase Formation cliffs and clear-flowing river create an impressive natural landscape, while the autumn foliage makes the valley particularly memorable.
The story of educator Makoto Hidaka adds another layer of interest. His vision of creating an ideal retreat among the mountains and his efforts to plant maple trees can still be felt around the former residence today.
With attractions such as Momiji-dani, the Mount Daifuku Observatory, Shiratori Shrine, and Umegase Chaya, the area offers more than a simple nature walk. Visitors can combine hiking, photography, history, and traditional culture while exploring one of the scenic mountain areas of Chiba Prefecture.
For travelers looking to experience the natural beauty of Japan away from the country’s major cities, Umegase Valley provides a peaceful opportunity to discover the forests, rivers, mountains, and seasonal scenery of the Boso Peninsula.
