As with much of Gangjin county, Gangjin-eup is largely agricultural and known for its rice, tomato, and persimmon harvests.

Gangjin county is known as a center for the production of Goryeo celadon, traditional Korean pottery.

Gangjin county is also home to several temples, and Gangjin-eup itself holds the birthplace of Yeongrang Kim Yun-sik, a well-known Korean poet of the 1930s and 1940s.

There is a monument to 17th-century Dutch explorer Hendrick Hamel, the first westerner to experience and write about Korea's Joseon Dynasty era.

Hamel and his men were shipwrecked on Jeju island, and they remained captives in Korea for 13 years.
