Perfume (パフューム) is a Japanese techno consisting of three members,,  and. The group have been active since early 2000 and are notable for being the namesake of Chocolate Disco, the first Stand in the series to be named after a Japanese song.

History
The group was formed in 2000 by Ayaka Nishiwaki, Yuka Kashino and former member Yuka Kawashima (河島 佑香) in the young talent academy in. Because the three of them had the kanji for "fragrance" (香) in their names, they decided to name the group "Perfume" (香水).

Kashino is infamous for being a big fan of JoJo's Bizarre Adventure. Her favourite part is currently Vento Aureo, and her favourite character is Giorno Giovanna. She also likes Bruno Bucciarati and Jotaro Kujo. When Perfume appeared on the TV show "Music Fighter" in April, 2009, Kashino revealed that JoJo's Bizarre Adventure was the thing that she was currently most into. Kashino initially disliked the series because of its crude art style, but later begun reading it after a JoJo fan passionately recommended it to her. In an interview with Perfume in the music magazine "What's In" from March 2009, Kashino also mentioned JoJo as the manga series that she was recently addicted to.

While on stage during the "Perfume Second Tour" in October 2009, Kashino talked about the appearence of Chocolate Disco in Steel Ball Run, saying that she was very happy to hear that one of her songs made it into her favorite manga.

On April 16 2010, Perfume made a guest appearance on the show "Happy Music" hosted by TV personality. During the show each of the members were asked to show things that make them happy, such as a "tagine pot" and "pajamas." Lastly, Kashino holds up volumes of Steel Ball Run to the camera and talks about JoJo. While this is happening, Kashino takes out photos revealing various figures she has in her room, including a copy of JOJO A-GO!GO!. Kashino also shows a photo of her bookshelf with over a hundred volumes of JoJo lined up side by side. At the end of the show, Becky and the other members of Perfume re-enact the cover of SBR Volume 14.

On March 1st 2010, Kashino was invited to Araki's house for an interview, though all the details are lost due to it only being posted on a "members-only" blog. The blog also featured a JoJo style picture of members of Perfume. In 2012, Kashino was also invited by Araki to the JoJo's Bizarre Adventure's 25th Anniversary commemorative party in Tokyo.

From an author's comment at the end of Ultra Jump March 2010, Araki describes coincidentally meeting A-chan while out shopping.

"Chocolate Disco"
"Chocolate Disco" (チョコレイト・ディスコ) was included as one of the two tracks featured on Fan Service [sweet] (ファン・サーヴィス [sweet]), the ninth single by Perfume. It was released on February 14, 2007. The song "Chocolate Disco" was later included as the fifth track on Perfume's debut studio album, released April 16, 2008. Following its release, GAME has been cited as one of the most successful techno pop albums of all time, with many of the the tracks being compared to French duo.

The song "Chocolate Disco" was used as the namesake for the Stand Chocolate Disco in Steel Ball Run, making it the first Stand in the series to be named after a song from a Japanese artist. People at the time speculated that the first Japanese Stand name would either be a song from Shoko Nakagawa or SOUL'd OUT, since both had close ties to Araki and were notable fans of the series. The inclusion of "Chocolate Disco" was very unexpected, as Araki is rarely known to listen to Japanese music.

Music producer, who wrote and composed "Chocolate Disco" for Perfume, said in an interview that his favorite manga was JoJo's Bizarre Adventure, and that he was impressed to find out about the appearance of Chocolate Disco in the series. Nakata was very happy to have his song featured as a Stand and would advertise it as such whenever he played it at events.

The name of Chocolate Disco was later changed in SBR Volume 17, noticeably having a different spelling than the one used in the single. The spelling of the user's name was also changed from "Disco" to "D-I-S-C-O."

Trivia

 * A popular fan comic depicting the members of Perfume with different Stands was created in June 2008. The comic showed with the Stand "Chocolate Disco." Interestingly, this was posted two months prior to Chocolate Disco's reveal in Steel Ball Run.
