# Jet Coaster Love

"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. The single was originally set to be released on March 23, 2011, but following the 2011 Great Tohoku Earthquake and tsunami disaster in Japan, the physical single was rescheduled to April 6, 2011. 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. It eventually became the group's first single to reach #1 on Oricon Daily and Weekly charts.
It was released in three different editions, 1 regular edition and 2 limited editions. The full single (excluding the bonus track) was released on iTunes Japan on March 16, 2011.

## Background

It was announced on January 26, 2011, that TBC (also known as 'Tokyo Beauty Center'), the largest aesthetic beauty salon chain in Japan is scheduled to release a commercial featuring all five members of group next month despite the ongoing controversy the group was facing with three of its members desiring to terminate their contracts. The group teamed up with TBC to headline the campaign, “Kirei wa, TBC kara” (“Beauty comes from TBC”). The group's name “Kara”, which also means “from” in Japanese, was cleverly incorporated into the slogan in order to further promote the group's position as spokespersons. However, it was still undecided as to whether or not the commercial theme song, "Jet Coaster Love", will be distributed digitally in the future.
It was later announced that it would be the group's third Japanese and will be receiving a physical release on March 23, 2011. It will be released in three different editions, 1 regular edition and 2 limited editions. The regular edition will feature a bonus track, “SOS (Army Slick’s 2011 bavtronic mix)". The Limited Edition A will come with a DVD with the promotional video, dance version and behind the scenes footage, and the Limited Edition B will come with a 32-pages photobook.
Following the 2011 Tōhoku earthquake and tsunami in Japan, Universal Sigma made an announcement that it will be postponing a number of its releases to different dates including Jet Coaster Love to April 6, 2011. The group later announced that they will be donating all their income from the single (both digital and physical) in order to help out with the Japanese relief and rescue efforts.

## Composition

The song, "Jet Coaster Love", is an upbeat tune which urges the listener to “fall in love”.
The B-side song "Ima Okuritai 「Arigatou」" was used as the ending theme song of the group's Japanese drama URAKARA. It was later included on the group's third Korean album Step as a bonus track under the title of "With My Heart (Dear Kamilia)" (Korean: 내 마음을 담아서 (Dear Kamilia)).
The first press of the regular edition comes with a bonus track, "SOS (Army Slick’s 2011 bavtronic mix)", a remix version of the song "SOS", which was previously included on their first Japanese studio album Girl's Talk.

## Music video

A one-minute preview of the promotional video for "Jet Coaster Love" was featured on Japan's Mezamashi TV on March 1, 2011. The full version was eventually released on March 3, 2011. The following week after the single's release, a music video for the B-Side, "Ima, Okuritai 「Arigatou」", premiered in MTV Japan on April 12, 2011. Both music videos were directed by Joo Hee Sun and were simultaneously filmed inside the studios of Seoul, South Korea.
"Jet Coaster Love" begins with the girls grooming themselves in front of a mirror at a beauty salon. 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. In another scene the members are individually seen sitting inside a white room filled with glittering disco balls while dressed in angelic white clothing.
"Ima, Okuritai 「Arigatou」" begins with the members preparing a letter and are wondering what to write in it. 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. Near the end they are seen standing under a white tree dressed in white bridal gown outfits while singing the song.

## Live performances

The group was originally scheduled to perform on Asahi TV's Music Station on March 18, 2011. However following the 2011 Great Tohoku Earthquake and tsunami disaster, the group was forced to postpone all promotional activities for Japan.
