Terra (stylized as TЁЯRA) is Konami's in-house rock and J-Pop group that composes music and soundtracks for Beatmania IIDX, Dance Dance Revolution, Pop'n Music, GuitarFreaks, and DrumMania. They first debuted in Pop'n Music 8 with their song "Stars☆☆☆". Their introduction in Konami's session simulation was "We Are" in GuitarFreaks 11th Mix & DrumMania 10th Mix. In Beatmania IIDX 10th Style, they were introduced into the DJ simulation series with the song "Doll". Since then, they've produced one song for each version of both IIDX and Gitado thereon, as well songs for the other active Bemani games. Their first album, Revolution was released on March 2005 and features longer versions of songs featured in the Bemani games, in addition to new songs.
On September 30, 2009, Terra closed their official site. Both Naoki and Jun stated this was because they were far too busy focusing on projects to update the site.
On September 7, 2011, Terra release their second album, Evolution.
The duo retired from Konami in September 2013 and their profile was removed from Bemani Fan Site's artist listing.
They are currently making new music for Capcom's music game crossbeats REV.SUNRISE.
