What is Uonuma City, Oku City Tadami? Introducing this secluded area rich in nature
The Tadami Oku , surrounded by mountains over 2,000 meters high, is located in the Kawakami , which flows along the border between Niigata and Fukushima prefectures.
Designated as part of the Echigo Sanzan Tadami-National Park, this area is home to extremely precious natural resources, with giant char and yamame trout swimming in Oku and golden eagles, a national natural monument, soaring in the sky.
This beautiful spot is visited by many people every year in search of nature.

Furthermore, Oku , which was created by the Tadami Oku , which boasts one of the largest water storage capacities in Japan, is a lake with beautiful scenery that has been selected as one of the "100 Best Dam Lakes."
The surrounding area once flourished as a silver mining area, but with the completion of the Tadami Oku , most of the remains of the silver mine now lie at the bottom of the lake. For this reason, locals affectionately call it "Ginzan Lake."

The western shore of Oku is called Ginzandai, and the name gives a sense of the silver rush of the Edo period.
[Access Guide] How to get to Oku
Tadami Tadami Oku from Uonuma city to Okutadami via the Okutadami Silver Line, a 22-kilometer-long group of tunnels. There are 19 tunnels, stretching a total of 18 kilometers. The scenery you can see from Oku the train as you Tadami along this road makes you feel like you've traveled back in time to another dimension.
This route takes about 40 minutes by car from Uonuma Interchange to Tadami Tadami . This is the shortest route to Oku .

There is also a local bus that runs from JR Urasa Station to Oku . Although it operates on limited days, it is recommended for those who are coming by secondary transportation or who are not confident in their driving skills.

How to enjoy it ①: Experience a cruise on Lake Oku that will make you feel like you're traveling abroad
First of all, if you visit Oku , we highly recommend taking a lake cruise on the Oku Pleasure Boat . From the lake, you can enjoy the vast expanse of nature before your eyes, and in the summer, you can feel the refreshing breeze.
There are four sightseeing boats in operation, each with a different design, but the one we recommend the most is the paddle steamer Fantasia.
The ship is modeled after a cargo-passenger ship that operated on the Mississippi River in the United States in the 19th century, and is characterized by its bright red paddlewheels and large size.

This boat takes you out to the observation deck on the third floor. The view from there is unobstructed, giving you a great sense of freedom! You can directly experience the wind and air blowing across the lake, making it a popular spot .

The interior of the ship is designed to recreate 19th century America. The retro wallpaper and seats are sure to look great in photos ! It will make your cruise feel like you've traveled back in time.

Every summer, Oku Tadami Boat offers a chance for children to experience being a captain.

This is a special summer vacation event and has become a popular one!
[User reviews]
・We took a leisurely cruise around Oku . We were able to fully enjoy the great outdoors while looking at the snow-capped mountains. The sightseeing boat was a three-story paddle steamer. The hull was elegant and the interior was also sophisticated. The breeze was pleasant and we enjoyed the 40-minute cruise. By chance, we were able to see a Japanese serow, a special natural monument. Next time, we would like to visit during the autumn foliage season. (Quote: Jalan )
・Just enjoying the magnificent scenery on a sightseeing boat is fun, but during the summer holidays, they were holding an event called "Children's Captain," where children were given uniforms, caps, and name tags to become captains. Before boarding the boat, there were also lots of gachapon machines, souvenirs, and gifts, so we had fun getting stamps and buying souvenir keychains. (Quote: Jalan )
How to Enjoy 2: The Popular Outdoor Activity! Try SUP (Stand-Up Paddleboarding) at Oku
The Ginzandai area on the west coast of Tadami is where meltwater from the 2,000m-high mountains joins Oku . The highly transparent water makes it the perfect place to enjoy splashing around in the water .

One of the activities you can enjoy at Ginzandai is SUP (Stand Up Paddleboarding) . This popular water sport involves standing up and using a paddle to paddle a board. Anyone can enjoy a casual cruise on the vast expanse of Lake Oku .

There are two locations in Ginzandai where you can register for SUP experiences.
SUP Experience 1. Uonuma Nature Lovers
Guides who are familiar with the nature of Uonuma City will provide you with the opportunity to "play" and "experience" in Uonuma. Why not relax on a board with your children or pet dog, or lie down and gaze at the sky , and enjoy the great outdoors at your own pace?

In addition to SUP, you can also try out various water activities such as canoeing accompanied by an instructor and E-boat riding (a large boat that can hold 10 people) .

[User reviews]
I participated in SUP activities three times in 2023, and this was the best service I've ever had. It was a cold day, and I was delighted to see the thoughtful hospitality of the users, with hot drinks and other items provided. They maintain a certain distance and only provide support when necessary. They cater to the user's skill level, so I think anyone can enjoy themselves. It was a valuable experience, experiencing the magnificent natural scenery. I'll definitely use it again next year! Thank you so much! (Quote: Jalan )

Furthermore , Ginzandai is a great place to splash around in the water, and just dipping your feet in the water on the lakeside is enough to cool you down , so it's also recommended as a way to cool off in the summer.

【Note】
There are places where the water suddenly gets deep and the current is fast. Please be sure to have a parent or guardian accompany you while you are enjoying the water.
Please be considerate to other anglers and those around you so as not to cause any inconvenience.
How to Enjoy 3: Catch a Giant Fish! Fishing Experience at Oku
Oku is also famous as a fishing mecca . Its greatest attraction is that you can catch large rock trout over 50cm long!

Because the lake is large, many people use boats to troll, cast, and fly fish, but it is also possible to fish from the shore.
A fishing license is required for fishing in any river, not just Lake Oku . You can purchase one at convenience stores in Uonuma City or at hotels in Ginzandaira.
For details on recreational fishing licenses, etc., please see here (Uonuma Fisheries Cooperative Association official website)

If you stay at a lodging facility in the Ginzandai area, you can also rent boats and other facilities.

How to enjoy ④: Experience nature observation and bird watching in Tadami !
Oku ishome to a wide variety of rare plants and animals , making it ideal for nature observation and bird watching.
If you're lucky, you might even come across natural monuments such as the golden eagle and the Japanese serow, as well as rare creatures like the Gifu butterfly and the ermine!

The image is a life-size wooden carving of a golden eagle. When its wings are spread, it measures an astounding 2 meters!

Be sure to check out the mountain slopes! You might even see a Japanese serow staring at you!
How to Enjoy 5: Oku Silver Line - An adventurous experience driving along a historic 22km road
One way to enjoy the area is through the long tunnel, the Oku Silver Line , on the way to Oku .

This road was built to transport materials for the construction of Tadami Dam . The area where the dam is planned to be built is a heavy snow area with snow accumulations exceeding 5 meters. This road played an important role in safely transporting materials, avoiding the dangers of avalanches and other dangers.
Despite the difficult construction, it was completed in just three years. Some parts still have rough, hand-dug walls, and the road still bears traces of its history .

Furthermore , the temperature near the center of the tunnel is kept below 20°C, making it a chilly spot in midsummer . This temperature difference can cause condensation to form on the outside of your car when you exit the tunnel. If you suddenly find yourself thinking, "My windows have fogged up!!", don't panic. We recommend opening the windows to eliminate the temperature difference between the outside and inside of the car, or cooling the windshield with the air conditioning to help the fog go away quickly!
*Please refrain from stopping or getting off inside the tunnel except in an emergency.
*Motorcycles are prohibited. There are periods when the road is closed during the winter.
How to enjoy ⑥: Relax and soothe yourself at Ginzandai Onsen! Refresh with the spectacular views and hot springs
When it's hot, we tend to seek out cool places, but the temperature difference can make you feel exhausted. When that happens, why not try relaxing in a warm hot spring? You'll be able to wash away the sweat and feel refreshed!
There are two day-trip hot spring facilities in the Ginzandai area.
At Shirogane no Yu, you can enjoy the hot springs in elegance while taking in the views of Mount Echigo-Komagatake and Mount Nakanotake. This hot spring boasts a cypress bath and cypress woodwork.

For more information on Shirogane no Yu, click here
The other "Kamoshika no Yu" is a day-trip hot spring facility located within the Ginzandaira Campground. Located in the middle of nature, you can enjoy forest bathing while soaking in the hot spring ! The gentle sunlight filtering through the trees is truly mystical.

For more information on Kamoshika no Yu, click here
How to Enjoy ⑦: Learn the Secrets of Dams at the Tadami Oku Power Museum! A learning spot that parents and children can enjoy
The Tadami Oku . It is located about a 7-8 minute walk up the slope from the Tadami Oku lot (bus stop).

The Power Museum, utilizing the latest digital technology, will reopen in the fall of 2023 ! Six large LED panels will be used to dynamically introduce the four seasons of Tadami and the history of dam and power plant construction . There will also be a trick art display of Otori Dam, nicknamed the "phantom dam" because it is off-limits. Visitors can enjoy taking immersive trick photos. Additionally, a tablet app that utilizes Augmented Reality (AR) technology, which overlays reality and the virtual world, will recreate the dam at their fingertips. The recreated dam can be displayed in each of the four seasons and viewed from all 360-degree angles.
The mascot of the Power Museum, Momota the Momonga, is adorable! Dam cards are also available!
