"Jet Coaster Love" (ジェットコースターラブ, Jetto Kōsutā Rabu) is the third Japanese single of South Korean girl group Kara.

In order to help out the areas affected by the disaster, the group had decided to donate all proceeds from the sales of this single, both physical and digital, to relief efforts.

A one-minute preview of the promotional video for "Jet Coaster Love" was featured on Japan's Mezamashi TV on March 1, 2011.

Both music videos were directed by Joo Hee Sun and were simultaneously filmed inside the studios of Seoul, South Korea.

Their reclining chairs then suddenly move on their own and takes the group into a dream amusement park called "Jet Coaster Love" as the song begins to play.

After arriving at the entrance, the girls are seen wearing white formal uniforms and then rides a Carousel adorned with origami-like swans serving as seats.

During the bridge, the members begin to write the letter using a quill pen and then places it inside an envelope before sealing it with a wax stamp.

On June 11, 2011, Music Station officially announced that KARA would indeed be returning in Japan and will be appearing on the show next week to perform a special medley of "Jet Coaster Love" along with their newest single, "Go Go Summer!".
