2. About 奥三面ダム

What Is It?

奥三面ダム is a concrete gravity dam built to regulate water flow for irrigation and flood control in the Murakami region. While the exact height and altitude remain undisclosed, the structure’s sleek silhouette against the surrounding forest creates a picture‑perfect backdrop for visitors.

History & Significance

Constructed as part of Niigata’s post‑war water‑resource development, the dam plays a crucial role in supporting local agriculture—particularly the famed rice paddies of the region. Its name, “奥三面,” translates roughly to “inner three faces,” reflecting the three tributary streams that converge nearby. Though not as famous as larger dams like the Kurobe, 奥三面ダム embodies the balance between modern infrastructure and the preservation of rural ecosystems.

Why Visit?

• Scenic Views: The reservoir mirrors seasonal colors—from cherry‑pink spring to fiery autumn foliage.
• Quiet Atmosphere: With few tourists, you can enjoy contemplative walks along the dam’s promenade.
• Photography Opportunities: The dam’s geometric lines juxtaposed with misty mountains make for striking shots.

3. How to Get There

By Train & Bus

1. Start from Tokyo: Take the Joetsu Shinkansen to Niigata Station (≈2 hours).
2. Transfer to the Uetsu Main Line: Ride to Murakami Station (≈1 hour).
3. Bus to the Dam: From Murakami Station’s west exit, board the local Niigata‑Koshi bus bound for “奥三面ダム入口” (Okusanmen Dam Entrance). The ride is about 30 minutes and the bus stops within walking distance of the dam’s parking lot.

By Car

Rent a car in Niigata City or Murakami and follow National Route 7 northward. After passing the city center, turn onto Prefectural Road 71 toward the dam. The drive from Murakami Station to the dam is roughly 15 km and takes about 25 minutes. Parking is available near the visitor’s center (free for day‑use).

By Bicycle

For the adventurous, the Shinano River cycling route offers a scenic 40‑km ride from Murakami to 奥三面ダム, passing rice fields, small villages, and river bridges.

4. Best Time to Visit

Overall, late April to early May and mid‑October are the peak photo‑op windows, but each season offers its own charm.

5. What to Expect

When you step onto the dam’s observation deck, you’ll be greeted by a calm reservoir that stretches toward the distant mountains. The area is equipped with a modest visitor center that provides multilingual pamphlets (Japanese, English, Chinese) and a small exhibition on the dam’s construction and its role in local irrigation.

• Walking Trails: A 1.5‑km paved loop circles the reservoir, with benches positioned at scenic overlooks.
• Picnic Spots: Designated grassy areas allow you to enjoy a packed lunch while listening to the gentle lapping of water.
• Wildlife: Keep an eye out for kingfishers, Japanese bush warblers, and occasional deer that wander near the forest edge.

Because the dam is primarily a functional infrastructure, there are no amusement‑park‑style attractions, but the peaceful ambience makes it perfect for meditation, sketching, or simply unwinding with a good book.

6. Nearby Attractions

While 奥三面ダム is the star of the day, the surrounding 7‑km radius boasts several natural highlights that can easily be added to your itinerary:

How to combine them: After exploring 奥三面ダム, hop on a local bus or drive to 三面ダム for a contrasting view of a larger reservoir. The two waterfalls, located roughly the same distance away, are best visited after a light hike—allow 30‑45 minutes each. The nearby spring offers a refreshing stop for a quick sip of crystal‑clear water (ensure you follow local signage).

7. Travel Tips

1. Check Opening Hours: The visitor center typically operates from 9:00 AM to 5:00 PM (seasonal variations may apply). The dam’s promenade is open year‑round, but facilities close at dusk.
2. Cash is King: Rural bus fares and small souvenir stalls often accept only cash (¥500–¥1,000).
3. Stay Connected: Mobile reception can be spotty near the dam; consider downloading offline maps beforehand.
4. Respect the Environment: As a functional water‑management site, swimming and fishing are prohibited. Dispose of trash in designated bins.
5. Photography Gear: A wide‑angle lens captures the dam’s full scale, while a telephoto lens helps isolate wildlife. A tripod is handy for low‑light sunrise shots.
6. Local Cuisine: Near Murakami Station, try the region’s specialty Murakami sushi (fresh Pacific salmon) and Koshihikari rice dishes.
7. Accommodation: For an immersive experience, stay at a minshuku (family‑run guesthouse) in Murakami town. Many offer home‑cooked meals using locally sourced ingredients.
