Gohan-eup and neighboring Sabuk-eup were both heavily dependent on coal mining to sustain its economy for many years. When coal began losing favor as an energy source to oil and natural gas in the 90's, the local economy began to struggle and lag behind. In October 2000, Kangwon Land, Gangwon's largest casino and entertainment company opened Kangwon Land Casino and Hotel in Sabuk-eup, boosting the economy of both of the towns immensely.
