Complete Guide to Gekkoukawa Dam Vicinity | Scenic Spots and Tourism Information in Yuza Town, Yamagata Prefecture
Gekkoukawa Dam, located in the mountainous area of Yuza Town in Yamagata Prefecture, is a hidden gem scenic spot where you can enjoy beautiful gorge landscapes of all four seasons with the majestic Mount Chokaisan as a backdrop. While serving as a flood control dam, it has become a popular area attracting many tourists during the seasons of fresh greenery and autumn foliage. This article provides a detailed explanation of the charm of the Gekkoukawa Dam vicinity, access methods, highlights, and surrounding spots.
Gekkoukawa Dam | Yamagata Prefecture’s First Dedicated Flood Control Dam
Dam Overview and History
Gekkoukawa Dam is a dam constructed upstream of Gekkoukawa River, which originates from the beautiful peak of Mount Chokaisan, also called the “Mt. Fuji of Dewa.” Completed in 1978 (Showa 53), it plays an important role as the prefecture’s first “flood control dam” built solely for flood control purposes.
Gekkoukawa is a distinctive river that flows rapidly down steep terrain and enters the Sea of Japan at Fukiura, with its basin encompassing most of Yuza Town. This river has long supported the town’s industries and nurtured regional culture as an important water source.
Structural Characteristics of the Dam
The greatest feature of Gekkoukawa Dam lies in its unique structure. It was constructed as a “composite dam (combined dam)” that combines concrete and rockfill sections, making it the first of its kind in Yamagata Prefecture.
The rockfill section employs asphalt-faced type waterproofing, which when combined with a gravity concrete dam design, realizes efficient flood control functions suited to the topography. This structure, reflecting the ingenuity of predecessors, holds high technical value, attracting the attention of dam enthusiasts.
Since flood adjustment is the primary purpose, the water level during normal conditions is maintained relatively low, and the appearance of the dam lake changes with seasons and rainfall.
Origin of the Name “Minonotsuma”
Gekkoukawa Dam is located at a point where three rivers converge. This geographical feature is the origin of the name “Minonotsuma (three confluences)” found upstream from the dam. The river extending northward continues toward the Minotsumi Gorge, forming a rich water system network in this region.
Scenic Points Around Gekkoukawa Dam
Appreciating the Gorge with Mount Chokaisan as Backdrop from the Bridge Over the Dam
The greatest charm of the Gekkoukawa Dam vicinity is undoubtedly the view from the bridge spanning the dam. From the bridge, you can enjoy a spectacular panoramic view where a deep gorge and mountain slopes in full color unfold against the backdrop of the majestic Mount Chokaisan.
Particularly, Mount Chokaisan appears so close from this viewpoint that it is said to be “within arm’s reach,” and you can sense its powerful presence intimately. On clear days, you can see details of Mount Chokaisan’s snow fields and rock faces, making it an excellent photography spot.
The vista from the bridge presents a different appearance with each season, revealing new discoveries with each visit. Early morning brings a dreamlike landscape enveloped in mist, daytime offers vivid contrast between blue sky and green, and sunset presents a beautiful scene where mountains are dyed golden.
Fresh Greenery Season | Mid-May to Early June
The fresh greenery period from spring through early summer is the season when Gekkoukawa Dam vicinity overflows with vitality. From mid-May through early June, mountainsides are covered with vibrant green, and trees along the gorge bud forth in unison.
During the fresh greenery season, various tree species display different shades of green, creating a landscape like a gradient. The subtle variations of green created by broadleaf trees such as Japanese beech, oak, and maple captivate viewers.
This season also offers mild temperatures, making it ideal for hiking and walks. You can fully enjoy nature in the fresh air, accompanied by the sight of new greenery and the sound of the stream.
Autumn Foliage Season | Mid-October to Early November
Gekkoukawa Dam vicinity is known as one of Yamagata Prefecture’s premier autumn foliage spots. From mid-October through early November, mountainsides are dyed in blazing reds and yellows, offering a dynamic autumn landscape.
During the foliage season, maples, nannyberries, and Japanese beech create vivid colors, and the entire gorge is enveloped in beauty reminiscent of a brocade painting. Particularly striking is the autumn foliage reflected on the dam lake surface, which has become a popular spot for photography enthusiasts.
In some years, the contrast between Mount Chokaisan’s first snow and autumn foliage can be observed, and the scenery woven by white, red, yellow, and green hues is truly worth seeing. Since the foliage peak varies slightly by year, it is recommended to check with local tourism associations for the latest information before visiting.

Precautions for Visiting the Gekkoukawa Dam Vicinity
Road Conditions by Season
Roads leading to Gekkoukawa Dam are closed during winter (generally December through early April) due to heavy snow. Spring opening times vary depending on snow conditions, so it is recommended to check with road management authorities or tourism associations before visiting.
During autumn foliage season and spring fresh greenery season, weekends especially see many tourists; visiting early in the day helps secure parking.
Clothing and Supplies
As the area is in mountains, temperatures are lower than in flat areas. Especially early morning and evening can be chilly, so bringing an extra layer is recommended.
For hiking and walks, wear comfortable shoes and bring drinking water and light snacks. Insect repellent spray also makes for a more comfortable visit.
Mobile Phone Signal
As the dam vicinity is in mountains, mobile phone reception can be weak or nonexistent in some areas. In case of emergency, it is recommended to inform family or acquaintances of your visit plans in advance.
Attention to Wildlife
As a nature-rich area, bears, wild boars, and other wildlife inhabit the region. Particularly at dawn and dusk, encounters are more likely; bringing a bear bell, making loud noises while walking, and similar precautions are recommended.
Photography Tips for Gekkoukawa Dam Vicinity
Photography Points
The most popular photography point at Gekkoukawa Dam is the view from the bridge spanning the dam. With Mount Chokaisan as backdrop, the one-glance view of the dam lake and gorge is captivating.
During foliage season, angles looking down from the bridge alone, as well as impressive compositions looking up at the bridge and dam from below the dam, are striking. Also recommended are compositions targeting the reflection of foliage and Mount Chokaisan on the water surface.
Best Times
When morning light illuminates mountainsides (approximately 8:00 to 10:00 AM), Mount Chokaisan shines beautifully and the gorge gains shadows, allowing three-dimensional photography. Afternoon (approximately 4:00 PM to sunset) sees western sun dye mountains golden, enabling dramatic photography. However, sunset times vary by season, so checking in advance is helpful.
Even on cloudy days, soft light embraces the entire gorge, allowing moody and atmospheric photography.
Equipment and Technique
Wide-angle lenses allow capturing the entire dam and surrounding mountains in a single frame. Telephoto lenses suit detailed photography of Mount Chokaisan or cutting particular gorge sections impressively.
Using a tripod enables smooth expression of water flow and blur-free photography even in low light conditions of dawn and dusk. Particularly during foliage season, ND filters enable long-exposure techniques for dreamlike expression.
