Yamabiko Bridge
No sooner than the torokko train leaves Unazuki station, the passengers see a big red bridge known as Yamabiko bridge. It's named after the echo (yamabiko) made by the torokko train passing the bridge. This is also a scenic area which is perfect for observing vivid green leaves in summer and variously colored leaves in autumn, making the two yamabiko bridges stand out.
Unazuki Dam
The Kurobe River originates in the center of Nother Japanese Alps and is one of Japan's most rapid rivers to harm the surrounding areas with floods. Unazuki Dam was built by Ministry of Land, Infrastructure, Transport and Tourism to prevent them. It is a 97-meter tall, also having such important functions as to generate electric power and suply water to the eastern Toyama prefecture.
Hotokeishi rock
At the hillside between Yanagi-bashi station and Mori'ishi station, there is a natural crag known as "Hotoke-ishi". Hotoke translates as Buddha while ishi as stone in English. It's called so as it resembles the image of Buddha. Many hikers pray to Hotoke-ishi for their safety before they set out for their mountain.
Kuronagi-onsen
Kuronagi onsen is the source spring of Unazuki onsen sites, releasing 2,000 liters of hot water per minute. The water is clear and colorless, smells of sulfur, and has the effect of making your skin smooth. The spring itself was discovered about 370 years ago, however, people were prohibited to enter the site by Kaga domain because the site provided an important path to other domains. So It was a "hidden hot spring" people secretly use, violating the domain's regulation.
It's in the late Edo Period that Kuronagi onsen was officially admitted as a public bath. In the Meiji Period, more people came to visit the onsen as the construction of the railway started and Kuronagi onsen ryokan was built.
