What is One Piece doing to keep it one chapter/episode?


Depending on how condensed the plot is in a manga, the number of episodes that
come out annually will be affected. For example, _Haikyuu!!_ had 25 episodes
per season for the first two seasons, and since it has almost caught up, there
will probably be 10-12 episodes per year from now on each covering 4-5
chapters, as 50 episodes got them to about chapter 150, if they want to stay
at pace with the manga.

In an action-based manga where a lot of the scenes are fighting scenes, it
becomes pretty hard to lengthen a chapter time-wise. What are specific time-
filling techniques _One Piece_ using to keep the chapter-to-episode ratio at
1:1?




The _One Piece_ manga and anime aren't in a 1:1 ratio. The distance between
them even shifts around. The second arc took place between the 8th and 24th
chapters in the manga, while the same in the anime took place between the 4th
and 8th episodes.

The main reason why the anime is this slow is the fillers. They help the manga
"catch a breath" and sneak in a couple of chapters. (side note: This is still
no excuse for fillers in the middle of an arc though).

Oda likes to put in a few filler episodes after every arc or when there's a
new movie out.

With these however, there's still a very big chance that the anime will
eventually reach the manga. If this happens, there are 4 possibilities:

  * They stop airing _One Piece_ for a year so the manga catches up.
  * They start airing the episodes every 2 weeks.
  * They do what _Game of Thrones_ will do/did and continue with a separate storyline.
  * They start writing the story for the anime and make the manga based on that.
