In the first OVA of Hidamari Sketch x Hoshimittsu, also sometimes referred to as episode 13, we see Natsume at a train station that's based on Musashi-Yamato Station in real life.

Stairs up to the station building.
The outsides of the station doesn't match any more since it was modified at the end of 2010.

Across the street from the station there's also a bicycle parking lot that's shown in the anime.
