2. About 留萌ダム

What is Rumori Dam?

• Name: 留萌ダム (Rumori Dam)
• Type: Multi‑purpose dam (primary function: water supply & flood control)
• Location: Rumoi City, Rumoi Subprefecture, Hokkaido, Japan
• Coordinates: 43.835362° N, 141.763330° E

Rumori Dam sits in the gentle lowlands of western Hokkaido, overlooking the Sea of Japan. While official documents do not disclose its exact height or altitude, the dam is an integral part of the region’s water‑management system, supporting local agriculture and protecting nearby communities from seasonal flooding.

A Brief History

The dam was constructed as part of post‑war infrastructure development aimed at modernizing Hokkaido’s rural economy. Its creation helped stabilize water supply for the surrounding farms, which produce rice, potatoes, and other staple crops. Over the decades, Rumori Dam has also become a modest recreational spot, attracting locals for fishing, picnics, and nature walks.

Why It Matters

• Environmental stewardship: The reservoir supports a healthy ecosystem, providing habitat for native fish species and migratory birds.
• Cultural relevance: The dam reflects Hokkaido’s commitment to balancing development with respect for the natural landscape.
• Scenic value: From the dam’s observation deck, visitors can capture sweeping panoramas of the Rumoi coastline, especially during sunrise when the sea mist dances over the water.

3. How to Get There

By Air

The nearest major airport is New Chitose Airport (CTS) near Sapporo. From there, you can rent a car or hop on a domestic flight to Asahikawa Airport (AKJ), then continue by road.

By Train

• JR Hakodate Main Line: Take the limited‑express “Super Hokuto” from Sapporo Station to Rumoi Station (approximately 2.5 hours).
• From Rumori Station, the dam is about 12 km away, so a taxi or rental car is the most convenient option.

By Car

Driving offers the greatest flexibility:

1. From Sapporo: Follow the Hokkaido Expressway (E5) to Rumoi Interchange (≈ 180 km, 2 hours).
2. From Rumoi City Center: Take Route 232 westward toward the dam; signage for “留萌ダム” is posted in Japanese and English.

Parking is available at the dam’s visitor area, free of charge.

Public Bus

Local bus routes (operated by Hokkaido Chuo Bus) run between Rumoi Station and the dam on weekdays, though schedules are limited. Check the latest timetables at the Rumoi City Hall information desk.

4. Best Time to Visit

Peak visitor months are May and October, when the scenery is at its most photogenic. Arriving early in the morning helps you avoid crowds and capture the best light.

5. What to Expect

6. Nearby Attractions

While Rumori Dam is a destination in its own right, the surrounding Rumoi Peninsula boasts several other dam sites and natural spots that make for a rewarding day‑trip circuit.

3. Bring Cash – Small rural shops and vending machines may not accept credit cards.

5. Respect Local Rules – Fishing requires a valid Hokkaido fishing permit; signage will indicate restricted zones.
6. Stay Connected – Mobile coverage is generally good in Rumoi, but some remote spots may have spotty signal. Download offline maps beforehand.
7. Eco‑Friendly Practices – Pack out all trash, stay on marked trails, and avoid feeding wildlife.
