Kurobe Dam is Japan’s tallest dam at 186 meters high and 492 meters long. It’s located in Toyama Prefecture and supports a hydropower plant. Built between 1956 and 1963, the dam was a massive engineering feat at the time and cost 51.3 billion yen (142.5 million USD) to complete. Although many issues arose during construction, the dam now helps supply the Kansai region with electricity.


The 2020 dates for the water discharge period are:

June 26 to July 31 (6 am to 5:30 pm)
August 1 to September 10 (6:30 am to 5 pm)
September 11 to October 15 (7 am to 4:30 pm)

The discharge period may be canceled depending on the weather.

Kurobe Dam can be viewed from a variety of spots, but this year, a new observatory provides a great close-up view. Built at an altitude of 1508 meters, it provides a direct view of the water discharge. There is also a photo service. For a fee, you can have your photo taken against the background of the dam by a remote camera on a hill.

Tateyama Kurobe Alpine Route

Tateyama Kurobe Alpine Route

Opened in 1971, the Tateyama Kurobe Alpine Route is a mountain sightseeing road that connects Toyama and Nagano Prefectures. Despite being only 37 kilometers (23 miles) long, the route has several scenic stops along the way as well as hiking trails. From the top of the mountain, it’s even possible to see Mount Fuji on a fine day. There are five different ways to traverse the alpine route, by funicular, bus, trolley, aerial tramways, and walking. It is important that no private transportation uses the route so that exhaust fumes do not harm the snow tunnels. During summer, shuttle buses also run between Toyama and Murodo. Closed annually from December to mid-April for its deep and inaccessible snows, the main attraction of the Tateyama Kurobe Alpine Route is the scenery provided by the Tateyama Mountain Range, which is part of the Chubu Sangaku National Park. From mid-April to late June the snow corridor, a snow wall that reaches 15 to 20 meters high, becomes a visitor-favorite vista. The rest of the year, the route remains a beautiful spot to see autumn leaves via the various hiking trails. And even offers a pathway to visit Kurobe Dam, which discharges water between late June and mid-October.
