If you’ve been patiently rewatching your Luffy collection and waiting for the next batch of One Piece episodes to drop on Netflix, the wait is almost over. Netflix has confirmed that Whole Cake Island Part 4 (Season 31, Episodes 823–835) is arriving on May 1, 2026 — and the Straw Hat crew’s Big Mom saga is about to get even more intense.

One Piece is one of the longest-running and best-selling manga and anime franchises in history, and Netflix has been steadily building its anime library arc by arc. Right now, the platform hosts 822 episodes (excluding the Egghead and Elbaf arcs), and next month that number climbs to at least 835.

How Has Netflix Been Adding One Piece?

Netflix has been on a consistent roll adding classic One Piece arcs over the past two years. In 2024 alone, it added the Marineford, Fishman Island, and Punk Hazard arcs. In 2025, it delivered the enormous Dressrosa arc (118 episodes!), Silver Mine filler, all three parts of Zou Island, and the first three parts of Whole Cake Island. The pattern is clear — Netflix is methodically working through the anime to complete the pre-Egghead catalogue.

What About the Wano Country Arc?

This is the big question on every fan’s mind. The beloved Wano Country arc — spanning roughly episodes 892 to 1088 — is one of the most acclaimed storylines in all of anime. Its addition to Netflix would mean every One Piece episode (pre-Egghead) is available on a single platform. Based on current pacing, fans are cautiously optimistic about a 2027 or 2028 arrival for Wano on Netflix.

Arc	Episodes	Estimated Netflix Arrival
Whole Cake Island (remaining parts)	836–891	2026 (TBC)
Wano Country	892–1088	2027–2028 (estimated)
