According to a report by the newspaper Sponichi, Toshi visited Yoshiki in Los Angeles in November 2006 to work on the song "Without You" as a tribute to hide.
On March 21, 2007, Toshi announced on his website that he and Yoshiki had recently resumed working together, stating that a "new project" would commence soon.
Rumors of an X Japan reunion subsequently began, and in June Yoshiki was reported as having expressed interest in a tour (beginning in Los Angeles), "Without You" being released as a single, and that he was in talks with Heath and Pata regarding their participation.

The band made its first public appearance on October 22, 2007, on the rooftop of the shopping center Aqua City in Odaiba, Tokyo, to film a music video for the newly recorded song "I.V.".
The song was used as the theme of the American horror movie Saw IV.
It was written by Yoshiki and recorded with all X Japan members of the pre-breakup lineup, as it utilizes previously unreleased guitar tracks by hide. "
I.V." was released through iTunes on January 23, 2008, topping the store's charts on that day.

On January 20, 2008, two Tokyo Dome concert dates were announced for March 28 and March 30.
Due to popular demand, they added another concert for the 29th.
These three shows were entitled X Japan Resume Attack 2008 I.V. – Towards Destruction, with each individual concert titled Night of Destruction, Night of Madness and Night of Creation, respectively, and featured three guest guitarists filling in for the late hide – Wes Borland, Richard Fortus and Sugizo.
The March 28 concert was aired live on the pay-per-view channel WOWOW.
During the song "Art of Life" a hologram of hide (taken from footage of the "Art of Life" performance at the Tokyo Dome in 1993) played alongside the band.
Because of technical difficulties, possibly due to the hologram, the first concert was delayed for over two hours and later came to an abrupt end when drummer Yoshiki collapsed eight songs into the performance.
The subsequent shows were without such difficulties and during a press conference, plans for a concert in Paris, France on July 5, 2008, were announced, with an intended audience of 20,000 people.
In addition to the Paris date, plans for concerts at the Madison Square Garden in New York City on September 13, and at the Taipei World Trade Center in Taipei on August 2 were also announced.
