The untitled X Japan album is an unreleased studio album by Japanese heavy metal band X Japan. Initially planned to be half new songs and half re-recordings of old songs, this was abandoned at some point in its 10 years of production in favor of all new material. Several different release dates were announced in that time, but the album remains unpublished despite drummer and bandleader Yoshiki confirming its completion in September 2018. However, several songs reported to be on it have been made commercially available digitally. If released, it will be X Japan's first album of new material in over 24 years, their first since reuniting in 2007, and their first to feature newest member Sugizo.
