Ogizawa Station is a mountain transportation hub in Omachi City, Nagano Prefecture, located at an elevation of approximately 1,433 meters and surrounded by the magnificent peaks of the Northern Alps. It is the Nagano-side starting point of the Tateyama Kurobe Alpine Route and the main gateway for travelers heading to the spectacular Kurobe Dam.
With a large parking area, the station is also convenient for travelers arriving by car. During the sightseeing season, visitors come from all over Japan to begin their journey into the mountains. The Ogizawa General Information Center beside the station provides information about the Alpine Route, transportation, weather, and sightseeing conditions.
Ogizawa Station serves as the eastern gateway to the Tateyama Kurobe Alpine Route, a spectacular mountain sightseeing route stretching approximately 37.2 kilometers between Ogizawa in Nagano Prefecture and Tateyama Station in Tateyama Town, Toyama Prefecture.
The route crosses the Northern Alps, where numerous peaks rise to around 3,000 meters. Located within the Chubu-Sangaku National Park, it takes travelers past some of Japan’s most dramatic mountain scenery, including Kurobe Dam and Murodo.
From Ogizawa Station, visitors board the Kanden Tunnel Electric Bus operated by Kansai Electric Power to travel through the mountain to Kurobe Dam.
This is a special transportation route that ordinary vehicles cannot use. The electric bus provides the only public transportation connection directly crossing this mountainous section between Nagano and Toyama.
Private cars are not permitted to travel through the section between Ogizawa and Tateyama Station. Instead, visitors transfer between specially designed public transportation services along the Alpine Route.
This restriction helps protect the fragile mountain environment of the Northern Alps. At the same time, traveling by bus, cable car, and other mountain transportation turns the journey itself into part of the sightseeing experience.
From spring greenery and alpine flowers to brilliant autumn foliage, the scenery changes dramatically with the seasons. Rather than simply being a way to reach a destination, the journey through the mountains is an essential part of the experience.
The Kanden Tunnel Electric Bus, also known as the e-Bus, connects Ogizawa Station with Kurobe Dam Station over a distance of approximately 6.1 kilometers. The journey takes about 16 minutes.
The buses travel through the Kanden Tunnel, which was excavated during the construction of the Kurobe No. 4 Hydroelectric Power Station. At its steepest sections, the tunnel has a gradient of up to 13 degrees.
The original Kanden Tunnel Trolleybus began operating on August 1, 1964. For decades, it played an important role in Kurobe Dam tourism and became famous as an environmentally conscious form of transportation because it produced no exhaust emissions.
Over its 54 years of operation, the trolleybus carried more than 60 million passengers and completed its long service without an accident.
The trolleybus made its final journey on November 30, 2018. From April 15, 2019, it was replaced by the current electric bus, which incorporates modern technology while maintaining the environmentally friendly concept of the original service.
The electric buses are equipped with lithium-ion batteries and use a vehicle-mounted pantograph charging system. At Ogizawa Station, they receive approximately 10 minutes of ultra-fast charging.
Because the buses produce no exhaust emissions while operating, they are particularly well suited to transportation through the environmentally sensitive mountain environment.
The electric buses also have several details that make the journey enjoyable for visitors. Hand straps inspired by Kuronyon, the mascot character of Kurobe Dam, are installed throughout the vehicle.
The cute design adds a playful touch to the journey and has become a popular photo opportunity for visitors.
The seats use three colors: Empowering Orange, Lime, and Turquoise. Together with the bright interior, the colors create a refreshing atmosphere that contrasts with the dark underground tunnel.
The Kanden Tunnel was excavated as part of the enormous project to construct the Kurobe No. 4 Hydroelectric Power Station. One of the greatest challenges during construction was a geological feature known as the fractured zone.
During excavation, approximately 660 liters of groundwater and sediment per second suddenly burst into the tunnel. The water was only about 4°C, creating extremely difficult working conditions.
Construction crews struggled for seven months before finally breaking through the fractured zone in December 1957.
The achievement became an important chapter in the history of Japanese civil engineering. The extraordinary difficulties involved in the construction of the Kurobe project later became widely known throughout Japan through the film Kurobe no Taiyo, helping to increase public interest in Kurobe and its spectacular mountain environment.
The present Ogizawa Station building has three floors, each serving a different purpose.
The first floor contains the ticket counters and general information desk. QR-code-compatible ticket gates are also provided for smooth boarding.
The second floor includes Restaurant Ogizawa and shops selling souvenirs and local products. Travelers can enjoy regional specialties such as Shinshu soba before or after their mountain journey.
The third floor contains the electric bus boarding platform as well as a rooftop observation area. From here, visitors can take in the impressive scenery of the surrounding Northern Alps.
Near the station, the Ogizawa General Information Center includes the Trolleybus Memorial Museum, where a preserved 300-series trolleybus is displayed.
The vehicle survived demolition and was eventually brought back to the area through a crowdfunding project. Today, it serves as a tangible reminder of the transportation history that developed alongside Kurobe Dam.
Visitors can also look inside the preserved vehicle, offering a glimpse of what travel through the Kanden Tunnel was like during the trolleybus era.
Ogizawa Station can be reached by local bus from JR Shinano-Omachi Station. Highway buses also operate from the Tokyo metropolitan area, including services from the Shinjuku area.
The station is also accessible by road from the Nagano and Hokuriku expressway networks. However, visitors should note that the Alpine Route and Ogizawa Station are closed during the winter season, generally from December 1 through mid-April.
Road closures may also occur during periods of heavy rain, so it is important to check transportation and weather conditions before setting out.
Ogizawa Station is far more than a transportation terminal. It is the starting point for an extraordinary journey into the Northern Alps, leading travelers toward Kurobe Dam, the Tateyama mountain range, and some of Japan’s most spectacular high-mountain landscapes.
The station brings together several layers of the region’s story: the clean technology of the electric buses, the engineering history preserved in the Kanden Tunnel, and the dramatic natural scenery of the Northern Alps.
From the fresh greenery of spring and alpine flowers in summer to the brilliant colors of autumn, each season offers a different perspective on the mountains.
For travelers exploring the Tateyama Kurobe Alpine Route, Ogizawa Station is the place where the journey truly begins. From here, the road disappears into the mountain, leading to Kurobe Dam and a remarkable world of alpine scenery, engineering history, and unforgettable travel experiences.
