Neighbouring subdistricts are (clockwise from the south) Yang, Kaeng, Non Sombun, Tha Pho Si, Klang, Phon Sawan, and Non Sawan. History
The tambon was named after the village in the area; however, such a village was later spilt off to create a new subdistrict, Phon Sawan, which is currently a tambon in Na Chaluai district and was further divided to establish a new administrative division, Non Sawan, where the Top Hu village is currently located. Previously, the tambon was administered by its subdistrict council (สภาตำบล), but the council was later upgraded to the Subdistrict Administrative Organization of Top Hu on February 23, 1997. In 1972, together with six villages split from Na Chaluai, three of the villages in Top Hu were broke off to form a new subdistrict, Phon Sawan, which currently is a tambon in Na Chaluai district.
