Departure was a major professional wrestling event produced by Pro Wrestling Noah. The event took place on July 10, 2004 at the Tokyo Dome in Tokyo, Japan, and marked Noah's first ever show in the arena. The main event was marketed as the culmination of the long running feud between former allies and tag team partners Kenta Kobashi and Jun Akiyama for the GHC Heavyweight Championship, then held by Kobashi. Beginning on Noah's very first show in 2000 and having spanned over four years since then, it marked the first time Akiyama and Kobashi had faced off in singles competition since August 6, 2000 where Akiyama won by referee stoppage.
