Kasukabe is home to what was formerly one of the two Robinsons department stores in Japan, which became a Seibu department store in March 2013. The large, seven-story American-style store is a landmark for residents. It is located on the east side of Kasukabe Station. However, Seibu is scheduled to close its doors due to a shortage of business, likely caused by competition with Aeon Mall.

Close to the west entrance to the station is a shopping mall, known as Lala Garden, housing several chain retail stores, such as Uniqlo, Gap, ABC-Mart, as well as a supermarket, 100-yen shop, and more. There is also an Ito-Yokado on the west side of the station.

In March 2013, an Aeon mall opened on National Route 16, which shoppers can either reach by car, or by taking a regularly scheduled bus from the east entrance of the station. This mall, as well as Lala Garden, has a movie theatre.

Kasukabe is the setting of the manga and anime series Lucky Star and Crayon Shin-chan. Shin-chan's creator Yoshito Usui also lived in Kasukabe.
