Taihei Lake and Komata Gorge Complete Guide | Access to Akita Prefecture’s Last Frontier, Highlights, and Best Seasons Thoroughly Explained
Taihei Lake and Komata Gorge, located in Kitaakita City, Akita Prefecture, are known as “Akita Prefecture’s last frontier” and are spectacular scenic spots. The artificial lake of Taihei Lake created by the Moriyo Dam and the primeval gorge of Komata Gorge spreading beyond it are valuable areas where untouched nature remains, designated as scenic beauties and natural monuments of the prefecture. This article provides thorough explanations of everything you should know before visiting, from the charm of Taihei Lake and Komata Gorge to specific access methods, trekking courses, and the best season to visit.
What are Taihei Lake and Komata Gorge? The Full Picture of Akita Prefecture’s Last Frontier
Overview and Features of Taihei Lake
Taihei Lake is an artificial lake created by the completion of the Moriyo Dam, boasting a circumference of approximately 30 km, an area of 195 hectares, and a maximum depth of 58 meters. Thirteen major and minor gorges and streams flow into the lake, with diverse fish species such as cherry salmon, char, carp, and pond smelt inhabiting it.
The entire area is designated as a special protection district within the nationally designated Moriyoshi Mountain Wildlife Conservation Area, preserving a naturally rich environment where many water birds reside. The sight of Mt. Moriyoshi reflected on the lake surface and the landscape created by columnar jointed rock walls never cease to fascinate visitors.
Geological Value of Komata Gorge
Komata Gorge (komata-kyō) is a valley spanning approximately 6 km in the area of the Komata River throughout the Noro River primeval forest at the eastern foot of Mt. Moriyoshi. This primeval gorge consists of more than one hundred waterfalls of various sizes, potholes (ouketsu), and deep pools, making it an area of exceptionally high geological value.
With primeval forest remaining untouched, the landscape where gorge beauty and forest beauty are unified is protected as a scenic beauty and natural monument of Akita Prefecture. Particularly noteworthy are the potholes created by water currents carving away rock over long periods of time and the diverse expressions of waterfalls created by complex terrain.
Why It Is Called “Akita Prefecture’s Last Frontier”
The reason Komata Gorge is called “Akita Prefecture’s last frontier” lies in the special nature of its access. To reach Komata Gorge, one must traverse Taihei Lake by sightseeing boat for approximately 30 minutes, making it inaccessible by land routes alone. This characteristic of being reachable only by boat heightens the atmosphere of a secret place.
Additionally, the gorge surrounded by primeval forest has been scarcely touched by human hands, preserving nature in its original state. Many areas have poor cellular phone reception, making it truly worthy of being called a modern-day frontier.
Detailed Information on the Taihei Lake Sightseeing Boat
Operating Period and Schedule
The Taihei Lake sightseeing boat (Komata Gorge shuttle taxi boat) typically operates from around June 1st when the lake opens until the end of October. Depending on fall foliage conditions, operations may be extended into early November.
Operations are affected by weather and lake conditions, so it is recommended to contact the Kitaakita City Tourist Information Center or the Taihei Lake Green House before visiting. Particularly at the beginning of spring or end of autumn, operating conditions tend to fluctuate.
Fares and Travel Time
The round-trip fare for the sightseeing boat is 1,400 yen for adults and 700 yen for children. One-way fares are also available, though return trips from Komata Gorge are typically made by boat.
Walking down the footpath approximately 400 meters (about 7 minutes on foot) from the Taihei Lake Green House brings you to the Kita-Shimizu boarding point. From there, the sightseeing boat takes approximately 30 minutes to reach the Komata Gorge pier. The return journey is shorter, about 10 minutes, as you travel with the lake current.
Spectacular Views from the Sightseeing Boat
The 30-minute sightseeing boat ride is a luxurious time to fully enjoy the beauty of Taihei Lake. You can appreciate the reflection of Mt. Moriyoshi on the lake surface, the towering columnar jointed rock walls, and the primeval forest thriving on the lakeshore—scenery that continuously transforms throughout the journey.
Especially during fall foliage season, the contrast of red and yellow trees coloring the lake surface is magnificent. Wildlife observation from the boat is common, making it a hidden gem for birdwatching. The captain often explains the highlights, providing information unique to locals, which is an additional attraction.
Komata Gorge Trekking Course Complete Guide
Overall Trail and Difficulty Level
From the Komata Gorge boat landing to the Sankairō Falls, approximately 1.8 km of footpath is maintained. The one-way travel time is approximately 45 minutes to 1 hour. For a round trip, including rest and photography time, you should allow 2 to 3 hours.
The footpath is relatively well-maintained, but as a mountain trail along the gorge, it features ups and downs with exposed rocks and tree roots in places. Wearing hiking boots or trekking shoes with good grip is essential. After rain, the trail becomes especially slippery and requires extra caution.
Detailed Introduction to Noteworthy Waterfalls and Pools
Along the Komata Gorge footpath, waterfalls and pools of distinct character appear one after another. Each is named, allowing you to enjoy the beauty of natural formations created by nature.
Yokotaki (Horizontal Falls) is relatively close to the boat landing, characterized by its unusual shape of water flowing horizontally across the rock face. Magaritaki (Curved Falls) is beautifully named after its meandering flow.
Gama-fuchi (Toad Pool) is a mystical deep green pool that changes expression depending on the light. Sankakutaki (Triangular Falls) is an elegant waterfall flowing down a triangular rock.
Anataki (Hole Falls) is a rare waterfall where water appears to spout from a hole in the rock, followed by the “Ke no” series—Ke no Fuchi (Ke’s Pool), Ke no Taki (Ke’s Falls), Ke no Seek, and Ke no Anataki (Ke’s Hole Falls)—a mystical area with legends of yokai (spirits) that once appeared here.
Sankairō Falls: The Highlight of Komata Gorge
At the end of the footpath awaits Sankairō Falls, the greatest highlight of Komata Gorge. This magnificent waterfall, approximately 20 meters high, splits into three tiers as it cascades down, making it the iconic symbol of Komata Gorge.
The roar of the falls, water spray, and the surrounding primeval forest create an atmosphere befitting the frontier, filled with mystique. You can approach close to the waterfall basin, experiencing its power up close. There is a rest area near Sankairō Falls where many visitors stop for lunch.

The Charm of Taihei Lake and Komata Gorge Through the Seasons
New Green Season (June to July)
The new green season beginning with the lake opening in June is a beautiful time when young leaves glow brilliantly. The fresh green foliage of beech and oak trees colors Taihei Lake in vivid greens, allowing you to enjoy trekking in refreshingly clear air.
During this period, temperatures are relatively mild, making it ideal for trekking. Water levels are also abundant, increasing the power of the waterfalls. However, this is a season when insects are plentiful, so insect repellent measures are essential.
Summer Season (August)
Summer at Taihei Lake and Komata Gorge is perfect as a retreat from the heat. Along the gorge, there is plenty of shade from trees, and cool breezes blow through. Trekking while bathed in water spray provides an exhilarating freshness that makes you forget the heat.
During summer vacation, many families visit, though the crowds are not as dense as during fall foliage season. The contrast between deep green forests and clear streams is beautiful.
Fall Foliage Season (Mid-October to Late October)
Taihei Lake and Komata Gorge shine brightest during fall foliage season. Typically beginning in mid-October, beech, oak, maple, and water oak trees begin to color, with the peak viewing period from mid to late October.
The contrast between the foliage reflected on the lake surface and the columnar jointed rocks is breathtakingly beautiful. From the sightseeing boat, enjoy a panoramic view of fall foliage; along the trekking trail, walk through canopies of changing leaves; witness the collaboration of Sankairō Falls and foliage—picturesque landscapes appear wherever you look.
This season is the most popular and can become crowded on weekends and holidays. An early morning start is recommended. Depending on foliage conditions, sightseeing boat operations may be extended into early November, so check the latest information.
