Urayama Dam

Completed in 1998 and officially commencing operations in 1999, Urayama Dam was constructed in response to the urgent need for flood control along the Arakawa River following the devastating typhoon of 1947 and the major flood disaster of 1967.

Today, the dam plays a vital role in flood prevention and water management while also serving as one of Chichibu’s well-known sightseeing spots. Often referred to as the “Lake of Chichibu Sakura,” the area becomes especially popular during cherry blossom season, when visitors can enjoy stunning views, tranquil surroundings, and the natural beauty of the region.

1.  History of Urayama Dam

The construction of Urayama Dam required the relocation of 49 households, making the negotiation process both sensitive and time-consuming. To support the affected residents, special government measures and compensation programs were introduced to assist them in rebuilding their lives in new locations.

Negotiations began in 1978 and were finally concluded in 1987, taking nearly nine years to complete. The dam itself was eventually completed in 1998, marking almost 28 years since the project first began.

Today, Urayama Dam serves multiple important functions beyond flood control. It supplies water to both Saitama Prefecture and Tokyo, while also contributing to hydroelectric power generation for the region.

2. How to Enjoy Urayama Dam Sightseeing

Also known as the “Lake Chichibu Sakura,” Urayama Dam is especially popular during spring, when cherry blossoms line the walking paths surrounding the reservoir, creating a peaceful and scenic atmosphere. Since 1994, parts of the dam’s interior have been open to the public, allowing visitors to experience not only the impressive engineering behind the structure but also the natural beauty of the surrounding area.

As one of the largest dams in the region, Urayama Dam can be seen from several points along the main road. Visitors who make their way to the top of the dam are rewarded with panoramic views overlooking Chichibu City. There is also a resource and exhibition room where guests can learn more about the history, development, and construction of the dam.

Fishing may also be available around the reservoir, depending on local conditions and regulations.

3. Access to Urayama Dam

If you are planning to visit Urayama Dam by public transport, it is worth noting that only a limited number of buses operate each day, so checking the timetable in advance is highly recommended. Buses to the dam depart from both Seibu-Chichibu Station on the Seibu Chichibu Line and Chichibu Station on the Chichibu Railway Line, with the journey taking approximately 15 to 20 minutes.

For a more convenient and flexible option, taking a taxi is recommended, as taxis are readily available at both stations.

Visitors looking for a more adventurous experience can also hike to Urayama Dam. By getting off at Urayamaguchi Station on the Chichibu Railway Line, it is possible to reach the dam on foot in around 30 minutes while enjoying the surrounding scenery along the way.
