right|thumb|270px|Asa Station is a passenger railway station located in the city of San'yō-Onoda, Yamaguchi Prefecture, Japan. It is operated by the West Japan Railway Company (JR West).[1] It is also the location of a freight depot operated by the Japan Freight Railway Company (JR Freight).
Asa Station is served by the JR West San'yō Shinkansen, and is located 509.5 kilometers from and 1062.1 kilometers from . It is also served by San'yō Main Line, on which it is 494.3 kilometers from the terminus of the line at . Asa Station is also the southern terminus of the 46.0 kilometer Mine Line to .
The station consists of two opposed side platforms sandwiching two island platforms connected by a footbridge for normal operations. Originally, it had four platforms and seven tracks, but platform 5 (opposite side of platform 6, Sanyo inbound siding) and platform 8 (opposite side of platform 7, Sanyo outbound siding) are no longer in use. Platform 4 is a central line with no physical platform and is sometimes used by freight trains. In the past, Platform 0 was installed in the cutout on the east side of Platform 1 and was used for the Mine Line, but now the tracks have been removed and a fence has been installed, making it inaccessible. Additionally, there are two opposed elevated side platforms for Shinkansen operations. The station is staffed.
Asa Station was opened on 3 December 1900 on the San'yō Railway when the line was extended from Mitajiri Station (present-day Hōfu Station). The San'yō Railway was railway nationalized in 1906 and the line renamed the San'yō Main Line in 1909. With the privatization of the Japan National Railway (JNR) on 1 April 1987, the station came under the aegis of the West Japan railway Company (JR West). The Sanyo Shinkansen station opened on 13 March 1999.,[2] making it the newest station on the Sanyo Shinkansen line.
Although nominally a freight deport for the Japan Freight Railway Company, freight has not been handled since 1984, but until 2013 there was a freight train that ran directly between the Mine Line and the Sanyo Main Line in the direction of Ube, so work such as replacing the locomotive was being carried out.
In fiscal 2020, the station was used by an average of 1167 passengers daily.[3]
