At this point in time the first six Blu-ray box sets had already been released, all of which featured Yamamoto’s musical score. The score was replaced with select pieces of Shunsuke Kikuchi’s original score from Dragon Ball Z. Shortly before the series’ syndicated broadcast ended, Toei Animation addressed issues of possible musical infringement in the series’ background music and promptly began removing Kenji Yamamoto’s score from all yet un-aired episodes, subsequent re-airings of episodes, and home video releases. The cover artwork for both the DVD and Blu-ray releases was drawn by veteran animator Tadayoshi Yamamuro. Each box set contained an exclusive “Dragon Book”, which included behind the scenes information on Dragon Ball Kai‘s remastering process, interviews with cast and staff, and high quality reprints of the DVD cover artwork. The first Blu-ray box set did contain an extra space to hold the starter Blu-ray disc.

As part of Toei Animation’s promotional strategy, the releases started off with a single-disc starter Blu-ray which was available at a reduced price per episode in hopes of providing fans incentive for purchasing the remaining box sets. Unlike the simultaneous DVD releases, the Blu-rays would be released in a standard fullscreen format as opposed to the widescreen format used for the series broadcast.

The first episode aired on 05 April 2009, and by June a home video release of the TV series had been announced, with the first Blu-ray released that September. In early 2009, Toei Animation announced that a “refreshed” version of the Dragon Ball Z TV series, re-titled Dragon Ball Kai, was being produced for a high-definition presentation in honor of the series 20th anniversary.
