Joseph's Walkman (ジョセフのウォークマン, Josefu no Wōkuman) is a recurring device that is featured at the end of every part where Joseph Joestar is present. The Walkman is a portable cassette player allowing Joseph to listen to music.
Joseph's Walkman is initially a Sony WM-701C at the end of Battle Tendency and Stardust Crusaders. It is black with a slim, sleek design and a compact rectangular shape. It has an integrated remote control and headphone socket. The top has buttons for opening, locking, and stopping the music, whereas the side has a volume slider and buttons to change tracks. Compared to its real-life equivalent, the headphone socket and buttons on the side are reversed.

Around 1987-1988, Joseph has a long conversation with Lisa Lisa. While heading to the airport to drop Suzi Q back home, he listens to a cassette of Ben E. King's songs, which he had recently grown fond of listening to.[6]
In the original Weekly Shonen Jump publication of Chapter 113, Joseph mentions that he is listening to Get Back by The Beatles on his Walkman. The name of the song is omitted in the volume release (as well as the TV Anime), but is still present on his cassette at the end of Stardust Crusaders.[7]
Joseph's Walkman was drawn by Hirohisa Onikubo in the last chapter of Battle Tendency. Hirohiko Araki purchased the same Walkman model for Reki Taki as a bonus at the end of 1988, which Onikubo referenced for his drawings. The earphones and cassette tape inside the Walkman also have the same appearance as what Taki was using at the time, although Taki wasn't listening to The Beatles.[8]
Joseph's Walkman makes a cameo appearance in the Stone Ocean anime's first opening, "STONE OCEAN". The director Kenichi Suzuki suggested that Kamikaze Douga could include motifs from the past parts during the scene where a pen falls on a piano. Kamikaze Douga's director, Junpei Mizusaki, searched for iconic items he could reference from the previous parts and included Joseph's Walkman falling on the piano as a result.[9]
