Funimation (UK and Ireland)

Manga Entertainment is a distributor of anime in the United Kingdom that began releasing One Piece on DVD and Blu-Ray in 2013. In May 2019 they were acquired by Funimation, the North American rights holder of the One Piece anime.

As of 2019, Manga Entertainment has released the first 491 episodes of the TV series and eleven of the Movies on home video and have scheduled a theatrical release of movie 14 for 2020.

TV Series
Manga's release of the One Piece TV series is identical in content to FUNimation's American releases, including the logo and credit alterations. Collections 1-13 use the PAL masters created by Madman, whereas Collection Fourteen onward are identical to the NTSC discs released by FUNimation (even refering to the US season releases in the menus). These releases contain audio in English 5.1 surround and Japanese stereo, and use the same subtitle translations as FUNimation's releases.

The 'In The Booth with Brina Palencia' special feature, which was advertised but not included with the US release of Season Five: Voyage Four, is included in Collection Thirteen. The Marathon Mode option is missing from the first thirteen collections. Otherwise, the extras are identical to their US counterparts.

Movies
The movies previously dubbed and released by FUNimation contain the English dub and original Japanese versions, whereas the others contain the Japanese version only. The movie packs use Manga's own masters with alternate subtitles that occasionally use names and terminology inconsistent to the FUNimation translations.

Movies 7-9
Movie 8 uses FUNimation's altered logo, but does not include the English credits.

Movie 8
This contains the same content as the 'Movie 7-9 Collection' disc.

Movie 12
The extras from the American and Australian releases are not included.

Reception
With Manga's first release of the series, several reviewers noted the high fan demand for an uncut DVD version following FUNimation's acquisition of the series in America six years earlier and the relative value of starting with the Collection sets, which each contain two of the Voyages initially released in America. Like the FUNimation releases, the uncut version and FUNimation dub were considered a more effective approach to the series than 4Kids' edited version as aired on TV. Some reviews criticized the earlier DVDs' video quality for including noticeable compression artifacts such as macroblocking, although these problems were noted to be less apparent in later volumes, particularly once the DVDs started using HD masters.

While the release of movies not licensed by Funimation was appreciated, the Movie Collection DVDs themselves were considered disappointing. The first Movie Collection was criticized for having poor video and audio quality, as well as translations that were not consistent with either the TV series DVDs or the other movie releases; several errors on the box for this release, incorrectly advertising an English dub, 5.1 audio and the short Dream Soccer King, were also noted. The video quality of the other two Movie Collections was much more positively received, but the films still contained a "disappointing" stereo soundtrack with "music and sound effects overpowering dialogue to the point of burying it completely" and subtitles with grammatical and translation errors. The audio and translation issues were carried over to the Blu-ray release of Movie 8, but did not affect movies 10 and 12.

Theatrical
Strong World was screened at BFI Southbank on May 16, 2014. A theatrical release of One Piece: Stampede is scheduled for February 2, 2020 in subtitled and dubbed formats.
