Sansai Station is served by the 37.3 km Kita-Shinano Line, and is 6.8 kilometers from the starting point of the line at Nagano Station.[2] Some trains of the Iiyama Line continue past the nominal terminus of the line at Toyono Station and terminal at Nagano Station, stopping at this station en route.
Station layout
The station consists of two opposed side platforms serving two tracks.[1] The platforms are connected by both a level crossing and an underground passage.
From 14 March 2015, with the opening of the Hokuriku Shinkansen extension from Nagano to Kanazawa, local passenger operations over sections of the Shinetsu Main Line and Hokuriku Main Line running roughly parallel to the new Shinkansen line were reassigned to third-sector railway operating companies.[3] From this date, Sansai Station was transferred to the ownership of the third-sector operating company Shinano Railway.
Passenger statistics
In fiscal 2016, the station was used by an average of 1,424 passengers daily (boarding passengers only).[4]
