Kurobe Dam, nestled between 3,000 m high mountains, is one symbol of Japan’s high economic growth after WWⅡ. Kurobe Dam was constructed in 1963 with over 10 million workers and a 7-year construction period.

Since we were children, we have heard lots of stories of how hard it was to build Kurobe Dam. It used to be so difficult to visit, but after the Toyama Shinkansen, a bullet train, opened in 2015, it has become much easier to access.

There are two gates to access to Kurobe Dam from Toyama Prefecture and Nagano Prefecture. From Toyama Prefecture, Tateyama Station is the starting point to visit by using Trolley, Cable Car, Ropeway and public bus. It takes about 3 hours to go through from Tateyama Station to Ougisawa Station in Nagano Prefecture, without sightseeing, with 6 types of public transportation. Recommended time is about 8 hours to visit and sea around Kurobe Dam. A one night stay would be much more preferable.

From Toyama Station, it takes one-hour to go to Tateyama Station by car or public transportation.

The length of Kanden tunnel is 5.4 km under Mt. Akazawatake and it was constructed to transport building materials. It took 19 months to connect Toyama and Nagano. People used to assemble logs to be carried through the valley to the Kurobe area from Ougisawa town and it took 2-3 days.

It took 7 months to tunnel through the fractured zone, blowing out cracked rocks and 4 degree water, due to its soft surrounding stratum. Digging the Kanden Tunnel was said to be the hardest part of the Kurobe Dam construction project.

Tateyama Kurobe Alpine Route round ticket is available and the valid period is 5 days. Along the Tateyama Kurobe Alpine Route, the connection is very smooth to transfer.

It takes 105 mins from Nagano Station to Ougisawa Station by public bus. It takes 3-4 hours to Shinano Oomachi Station from central Tokyo.

You can visit the West Area via Toyama and Nagano prefectures from Tokyo, but it takes time to transfer. Although renting a car is not necessary to visit Kurobe Dam, traveling in Toyama and Nagano Prefectures is much more convenient with a rent-a-car.
