This is a station on the Kurobe Gorge Railway Main Line.
General passengers are not allowed to board or alight here; it functions as a dedicated station used for maintenance of Kansai Electric Power Company's power facilities.
The origin of the station's name, "Moriishi," is said to come from the Edo period, when the Kaga Domain conducted patrols of the Kurobe Okuyama area. It is believed that there was a large stone at the boundary between privately owned land and land directly controlled by the Kaga Domain. From this, the name "Moriishi" (meaning "stone in the forest") was derived, as explained by the Kurobe Gorge Railway.
This is an interchange station with one island platform and two tracks.
As this station is exclusively for Kansai Electric Power Company, general passengers cannot disembark.
There is a siding that makes use of the old railway line, and is used to store passenger cars during the off-season and to store vehicles scheduled for scrapping.
I couldn't get off here, so I just took a picture. On the return trolley, the conductor told me there were monkeys, but they passed by before I could get my camera out. They seem to appear around here often. It depends on your luck, but it might be a good idea to be prepared.
