One Piece After Box Set 4: Volumes and the Next Box

One Piece Box Set 4 ends at volume 90. The announced Box Set 5 covers volumes 91–111, with a publisher-listed release date of December 8, 2026. As checked on September 9, 2026, that fifth box is a future release and is not included as an owned or currently released candidate in this site’s calculator.

Establish what the first four boxes cover

VIZ lists the ranges as 1–23, 24–46, 47–70 and 71–90. Together these cover volumes 1–90 without a numbered-volume gap. The Box Set 4 product page identifies the 71–90 range; all four source records appear in the One Piece edition map.

“Complete” in a tool result refers to the target you selected. It does not mean that volume 90 ends the series or that no later individual volumes exist.

What if you already started buying later singles?

The announced Box Set 5 page gives an ISBN of 9781974769421 and the 91–111 contents. Using that announced membership, a reader with singles 91–100 would have ten overlapping volumes and eleven new ones, 101–111, if they later obtained that exact set. A reader with 91–111 would gain no new numbered story coverage.

Those are calculations about the announcement, not a statement that the box is shipping, in stock or the cheapest way to fill a shelf. Release dates and product details can change. Recheck the publisher before making a decision based on a future set.

Decide what you are trying to complete

If your immediate target is volume 90, the first four boxes may already cover it. If your target extends further, list the later singles you actually own separately before judging a box. Do not erase those holdings because you intend to replace them with a matching format.

The calculator stays bounded to its audited, released range. This article keeps the future announcement separate so that a release schedule cannot silently become a claim about ownership or present availability. A future update should recheck both the release and the exact contents before adding a new selectable record.

If you are changing format as well as continuing, the omnibus-versus-box comparison works through original volumes 88–93 and shows which purchases repeat books you own.
