The station was opened on 16 December 1996, as part of the first phase of the STAR system's opening, alongside 13 adjoining stations along the Sultan Ismail-Ampang route.
Location
The Miharja station is situated at the southwestern side of the Miharja Flats, a complex of flats close to Kerayong River in the locality of Taman Miharja, off Jalan Loke Yew (Loke Yew Road). The station directly serves the aforementioned flats, as well as the remaining portion of Taman Miharja and the Ue3 shopping centre from the opposite side of Jalan Loke Yew, which also have similarly close access to Maluri station.
Overall, the Miharja station was built as a low-rise station along two tracks for trains traveling in opposite direction. Because the station is nearly subsurface and features two side platforms, the station designates individual ticketing areas for each of the station's two platforms at their level, ensuring access to trains traveling the opposite direction is not freely possible.
The principal styling of the station is similar to most other stations in the line, featuring curved roofs supported by latticed frames, and white plastered walls and pillars. Because stairways are only used to link street level with the station's ticket areas and platforms, the station is not accommodative to disabled users.
