Dragon Ball Z Kai is a revised, remastered version of Dragon Ball Z, not a sequel. It retells the same core story with a re-edit intended to follow Akira Toriyama’s original tale more closely, plus updated picture, sound, music, and recorded performances. The main choice is between Kai’s revised presentation and the original television version.
How are Dragon Ball Z and Dragon Ball Kai related?
Dragon Ball Z is the original television anime version of this part of the Dragon Ball story. Dragon Ball Z Kai revises that series: Toei Animation calls Kai “a revised version of the anime series Dragon Ball Z,” while the U.S. distributor described it as retold to follow Toriyama’s original tale more closely.

That description does not mean every anime-only scene was removed. The official sources cited here do not provide a complete list of edits or a full inventory of material retained or cut, so claims about specific scenes should be checked against the relevant version.
What are the main differences?
| Feature | Dragon Ball Z | Dragon Ball Z Kai |
|---|---|---|
| Version | The original television anime presentation. | A revised version of Dragon Ball Z, not a separate sequel. |
| Story edit and pacing | The original broadcast edit. | Re-edited and described by its U.S. distributor as following Toriyama’s original story more closely. The sources do not supply a complete edit list or a quantified comparison of pacing. |
| Picture | The original presentation. | Remastered in high definition, described by Toei as clearer and more vivid. Remastering does not establish that the series was fully redrawn or newly animated. |
| Sound, music, and performances | The original series soundtrack and performances. | Updated sound and music, with re-recorded performances. Fuji Television says familiar cast members returned, but the cited sources do not provide a complete cast-by-cast comparison across languages and regions. |
| Catalog length | A directly comparable total is not stated in the sources cited here. | Toei Animation’s current catalog lists 167 episodes of 26 minutes each. Regional versions and cuts may differ. |
What does “remastered” mean for Kai?
Toei describes Kai’s picture as remastered in high definition. Fuji Television characterizes it as clearer and more vivid, and says the series also has updated sound and music. The U.S. distributor called Kai a re-edit and remaster. These descriptions support an updated presentation, not a claim that the animation was entirely remade.

The audio and performance changes are part of the revision, but they are not a universal cast replacement: Fuji says familiar cast members returned. The available official descriptions do not specify every change in every language edition.
Which one should you watch?
Choose Kai if you want the revised presentation
Kai is the practical choice if you want a remastered picture, updated audio, and a retelling that its distributor says follows the original story more closely. Toei’s catalog lists it as 167 episodes at 26 minutes each, though that listing should not be treated as a guarantee that every territory’s release has identical contents.
Choose original Z if you want the original television version
Watch Dragon Ball Z if your priority is seeing the series in its original broadcast presentation. The sources cited here do not establish a direct episode-count comparison or settle subjective questions about which version’s pacing, music, voice performances, or particular scene choices viewers will prefer.

Toei’s catalog gives Kai a production date of 2009. A 2010 U.S. distributor announcement says it premiered on Fuji Television in April 2009. The announcement, dated February 25, 2010, also described DVD and Blu-ray releases beginning that spring, with Part One scheduled for May 18, 2010; those are historical release details, not evidence of present-day availability.
