Luna Sea is one of the bands that made {{Visual Kei}} popular in Japan. Originally called Lunacy, the band was founded in 1986 by schoolmates Inoran (guitar) and J (bass). In 1989, Ryuichi joined as vocalist, bringing {{Music/Sugizo}} as a lead guitarist and occasional violinist, and Shinya joined as their drummer. They have stayed in this lineup ever since.

Shortly before they released their first album, they changed their name to Luna Sea, justifying a lot of pv's and stage decorations featuring either sea and water or moon later on. Their tendency to release important information on a full moon day and name their concerts after moon phases might also have something to do with that. In 1992, they were discovered by [[Music/HidetoMatsumoto hide]] of Music/XJapan and signed to [[Music/YoshikiHayashi Yoshiki]]'s label Extasy Records (which they left at the end of that year to sign with a major label). They were very successful in the 90's, though they abandoned their [[EightiesHair wilder hairstyles]] and looks for a tamer version (aka the boyband look) pretty soon.

Focusing mostly on rock, the band has accomplished a variety of sounds over their careers, each showcasing the progressive songwriting talents of the band members. Their early career is characterized by a very 80's sound, mixing elements of grunge, metal, punk, and a hint of neo-classical into their playing. The band is known among fans for having a "mysterious" sound.

In 2000, they announcend an indefinite hiatus, as each of the members pursued their own solo careers, several of them finding great success. In August of 2010, this hiatus was ended, and the band announced that they were both going on tour again and writing new songs.

!!Luna Sea provides examples of:
* EightiesHair - in their early Visual Kei days, downplayed by Ryuichi and Inoran in their 20th anniversary concert ''lunacy''.
* AllDrummersAreAnimals - Ever seen Shinya with long, unkempt hair and mustache, "talking" to the audience after a strenous and sweat-inducing drum solo? Thought so.
* AlternativeForeignThemeSong: "Sweetest Coma Again" was the theme song for the Japanese release of the ''Film/JamesBond'' film ''Film/TheWorldIsNotEnough''.
* BSide - There are even two albums of B-Side Singles: ''Singles'', Disc II (1997) and ''Another Side of Singles'' (2002), and their fan club is called after one: ''Slave'', B-Side of ''In My Dream (With Shiver)''
* EpicRocking - ''Rain'', ''Genesis Of Mind'', ''Till The Day I Die'' and ''The One -Crash to Create-''.
* {{Fanservice}} - Inoran, Ryuichi and Sugizo, mostly.
* ForeignLanguageTitle - Arguably, since all their titles are in English (except one: Kono Sekai No Hatede), yet there is very few English in the actual songs.
* GreatBallsOfFire - Take a Shinya solo, any Shinya solo.
* GreatestHitsAlbum: ''Period ~The Best Selection~.''
* HellBentForLeather: Everyone at various points, with Shinya as the notable exception. He prefers the fur to the hide.
* LongRunnerLineUp: They lasted from 1989 to 2000, then reunited in 2010.
* MetalScream: Prominent in their early albums, as Ryuichi would start a song clean, and slowly get grittier until shouting at the chorus, for an intense build of suspense.
* PerformanceVideo: "Dejavu," "Rosier," "In Silence," "Desire," "End of Sorrow," "Storm," "Shine," and "Tonight."
* PuttingOnTheReich: Sugizo in photographs and TV performance. Ironically, he dislikes glorifying UsefulNotes/ImperialJapan and UsefulNotes/NaziGermany.
* PuttingTheBandBackTogether: Literally, in 2007 for a Christmas concert, in 2008 for the [[Music/HidetoMatsumoto hide]] memorial summit, and for real in 2010 after ten years of inactivity.
* SelfTitledAlbum: Two of them. ''Luna Sea,'' their first, and ''Lunacy,'' their last. The band's original name was "Lunacy," before they got signed.
* VocalTagTeam: Minus vocal plus violin for "Providence" (it's pretty much Ryuichi's and Sugizo's song).
