ORESAMA released their new single Hi-Fi TRAIN, the lead song in ORESAMA’s first major album “Hi-Fi POPS” which will be released on 11 April 2018. Hi-Fi TRAIN portrays the liberation from the physical world of reality characterized with "sea of asphalt" and "pedestrian scrambles". The lyrics suggest blocking out these noises with this song and that the experience of listening to this music is akin to boarding a Hi-Fi TRAIN which enables one to soar up beyond the stars to a place of dream. Also, it promises to show an unseen new world.

It is filled with motivational messages like "going straight ahead at full speed" and that "there's no meaning if one doesn't enjoy life". The video is very much in line with the lyrics where the world lit up with dynamic neon lights after the female lead, vocalist Pon, enters the television box which showed Utomaru's artwork, the design for this album. Upon leaping into the world of music, the train sets off from Shibuya and headed off far into the galaxy where the dreams lie.

ORESAMA’s second live tour “TRUE TOURS 2018~Lonely Queen’s Liberation Party~” has also been confirmed. The tour will run from 16 June 2018 to 29 July 2018 at various locations around Japan which include Yokohama, Nagoya, Kyoto, Osaka and Tokyo.
