Overview
Nestled amidst the picturesque landscape of Toyama Prefecture in Japan lies a testament to human perseverance and ingenuity - the remarkable Kurobe Dam. This engineering marvel stands proudly along the Kurobe River, a vital component of the region's hydroelectric infrastructure, weaving together the natural beauty of the Tateyama Mountain Range in the Northern Alps.
Standing at a height of 186 meters, the Kurobe Dam holds the distinction of being the tallest structure in Toyama Prefecture, its imposing presence a testament to the indomitable human spirit. Yet, behind its imposing facade lies a story of hardship and sacrifice. The total construction cost of 51.3 billion yen at the time of its inception was a staggering five times the capital of the Kansai Electric Power Company, underscoring the enormity of the undertaking. Over the course of its construction, 171 brave souls lost their lives.
How Kurobe Dam Overcame Power Shortages in 1950s Japan
In the Kansai region（Nara, Wakayama, Kyoto, Osaka, Hyōgo and Shiga, Mie）, frequent power outages became a grim reality, threatening to stifle the burgeoning industries and disrupt the daily lives of millions.
As factories and households grappled with restricted electricity usage, the need for a reliable and sustainable energy source became increasingly urgent.
Against this backdrop of uncertainty, the construction of the Kurobe Dam emerged as a beacon of hope.
From the laborers who braved the treacherous terrain of the Kurobe Gorge to the engineers who meticulously planned its construction, every step forward was a testament to the human capacity for perseverance in the face of adversity.
Construction of the Kurobe Dam commenced in 1956, a time when the promise of electric power development beckoned with the allure of progress and prosperity.
Construction commenced in July, with thedaunting task of building the dam entrusted to five different construction companies, each responsible for a specific section of the project. From the water intake and conveyance tunnels to the penstock pipelines and power station, every aspect of the dam's construction required meticulous planning and execution.
The remote location of the constructionsite posed significant challenges, necessitating the transportation of materials by foot, horse, and even helicopter.
The construction of the Kurobe Dam was not without its perils. In the rugged terrain of the unexplored Kurobe Gorge, where life-threatening conditions lurked at every turn, every step was fraught with danger.
The phrase "one person will die for every 10,000 kW produced in electric power development" echoed ominously throughout the construction site, a grim reminder of the risks inherent in the pursuit of progress.
Yet, despite the odds stacked against them, the workers pressed on, driven by a sense of duty and a shared belief in the transformative power of their endeavor.
To overcome these obstacles,cutting-edge technologies were employed, including the construction of the Omachi Tunnel (now known as the Kansai Electric Power Tunnel) to facilitate access to the dam site.
One of the most remarkable feats ofengineering during the construction process was the breakthrough of the fracture zone inside the tunnel. Utilizing innovative techniques such as chemical hardening and concrete grouting, engineers successfully navigated through the challenging terrain, significantly reducing the construction period.
Amidst the backdrop of these Herculeanefforts, the foundation stone laying ceremony for the dam took place at Omaezawa on September 18, 1959, marking a significant milestone in Japan's quest for energy independence. Over the following years, as flooding ommenced and the dam took shape, the dedication and commitment of those involved in its construction became increasingly evident.
Finally, on June 5, 1963, the Kurobe Dam was completed, a towering symbol of human achievement and resilience. The culmination of years of hard work and determination, its completion was celebrated with a visit from the Crown Prince and his wife, underscoring its importance to the nation.
The completion of the Kurobe Dam heralded a new era of prosperity for the region, ushering in the creation of one of the largest artificial lakes in the Hokuriku region - the breathtaking "Kurobe lake."
With a total water storage capacity of 200 million tons, this vast reservoir is not only a source of hydroelectric power but also a testament to the symbiotic relationship between human innovation and the natural world.
In the shadow of the Kurobe Dam, travelersfind inspiration to confront their own challenges with courage and conviction.
It is a reminder that, even in the face of adversity, there exists the potential for greatness - a legacy that continues to inspire and captivate visitors from around the world. As travelers depart from its shores, their hearts are filled with a newfound appreciation for the wonders of Japanese technology and the remarkable story of the Kurobe Dam - a story of courage, hard work, and the triumph of the human spirit.
Exploring the Kurobe Dam Along the Tateyama Kurobe Alpine Route
the Kurobe Dam offers an unforgettable experience amidst the pristine beauty of the Chubu Sangaku National Park. As one of Japan's most representative dams, it serves as a highlight along the famed Tateyama Kurobe Alpine Route, attracting visitors from far and wide.
From Tateyama Station, travelers board a cable car, followed by a hybrid bus at Bijodaira Station, a trolley bus at Murodo Station, and a ropeway at Daikanbo Station. Finally, they arrive at Kurobedaira Station, where they transfer to a cable car for the ultimate ascent to the dam. On the Nagano Prefecture side, electric buses departing from Ogizawa Station provide access to this awe-inspiring destination.
Operated by the Kansai Electric Power Co., Ltd., each tourist facility at the Kurobe Dam offers a unique perspective on this iconic landmark. From interactive exhibits to awe-inspiring viewpoints, visitors can immerse themselves in the rich history and natural beauty of the dam.
As the waters of the dam lake cascade down from late June to mid-October, travelers are treated to a mesmerizing spectacle of nature's power and beauty. Whether marveling at the engineering marvels of the dam or embarking on a scenic hike through the surrounding mountains, a visit to the Kurobe Dam promises an unforgettable experience that will inspire awe and wonder for years to come.
