Complete Guide to Ōchi River Gorge and Kanagura Falls (Saitama Prefecture) | Autumn Foliage Peak Season, Access, and Nearby Attractions
Located in the Ōtaki district of Chichibu City, Saitama Prefecture, the Ōchi River Gorge is a spectacular scenic spot created by the nature of the inner Chichibu region, and is particularly a renowned autumn foliage destination visited by many tourists and photographers during the fall season. Among these, the area known as “Kanagura Falls” is known for its beautiful scenery of mountain streams and autumn colors. This article introduces the charm of Ōchi River Gorge and Kanagura Falls in full.
What is Ōchi River Gorge and Kanagura Falls?
The Ōchi River Gorge is a ravine that spreads along the Ōchi River flowing through the Ōtaki area of Chichibu City, and is located along National Route 140 (Saiko-Kai Highway). “Kanagura Falls” refers to a particularly scenic location near the entrance of this gorge and is cherished as the gateway to tourism in the Ōchi River Gorge.
The Origin of the Name Kanagura Falls
The intriguing name “Kanagura Falls” has an old legend behind it. It is said that travelers captivated by the extraordinarily beautiful scenery of the ravine would lean over to peer into the valley, and many would drop their kanagura (wallets) that they had in their pockets, which is how the place got its name. The scenery is so breathtaking that it captivates people to such an extent.
Historical Background of the Ōchi River
The ominous name “Ōchi River” (大血川) also has historical origins. After the death of Taira no Masakado, his wife Kikyo and 99 attendants fled to Daiyo Temple upstream, but they were cornered by pursuers and committed mass suicide near the source of the river. According to legend, the river water turned red for a time, which is how it came to be called the “Ōchi River” (literally “Great Blood River”). Knowing this historical background adds a different dimension to appreciating the gorge’s scenery.
The Charm of the Ōchi River Gorge and Kanagura Falls Autumn Foliage
Types of Trees That Change Color
The Ōchi River Gorge features a diverse range of trees that display vibrant autumn colors. The main foliage trees are as follows:
- Japanese Maple: Bright red colors adorn the gorge
- Acer: Display a variety of colors from deep crimson to orange
- Nana Kamado: Characteristic bright red foliage
- Beech: Golden leaves shine in the autumn light
- Azalea: Add shades ranging from red to purple-tinted colors
The gradient created by these trees is truly a masterpiece created by nature.
Contrast Between Mountain Streams and Autumn Foliage
The greatest charm of the Ōchi River Gorge is the contrast between the clear stream and the autumn foliage. Since you descend through the gorge from National Route 140, you can enjoy the foliage from below, creating an ideal scenic backdrop for a drive. The foliage reflected in the blue water surface and the contrast between the rocky cliffs and the colored trees are perfect for photography.
As you proceed along the walking path, there are multiple viewpoints where you can see the stream and autumn foliage simultaneously. Particularly, in places slightly further into the gorge from Kanagura Falls, you can enjoy a spectacular view where the flow of the stream and foliage become one.
Autumn Foliage Peak Season and Color Development Status
Peak Season
The autumn foliage of the Ōchi River Gorge and Kanagura Falls typically progresses according to the following schedule:
- Beginning to color: Late October
- Peak foliage: Early November to mid-November
- Leaf fall: Late November
Depending on altitude and temperature, the progression of coloring varies, but the approximately two-week period from early to mid-November is the best time to enjoy the most beautiful autumn foliage. Because of its relatively high altitude among Saitama Prefecture’s autumn foliage spots, the foliage develops earlier than in lowland areas.
Oku-Chichibu Ōtaki Autumn Foliage Festival
To coincide with the autumn foliage season, the “Oku-Chichibu Ōtaki Autumn Foliage Festival” is held annually from late October to mid-November. During this event period, special programs are sometimes held at surrounding tourist facilities and restaurants, allowing you to enjoy a more enriched Chichibu experience.
We recommend checking the latest foliage status on the Chichibu City Tourism Association website and related facilities before visiting. The peak season timing may shift depending on weather conditions, so advance information gathering is important.
