One Piece

Oda's work program includes the first three days of the week dedicated to the writing of the storyboard and the remaining time for the definitive inking of the boards and the possible colouring.

Oda's primary inspiration for the concept of Devil Fruits was Doraemon; the Fruits' abilities and uses reflect Oda's daily life and his personal fantasies, similar to that of Doraemon's gadgets, such as the Gum-Gum Fruit being inspired by Oda's laziness.

Eisaku Inoue, an animation director at Toei Animation, noted that these kanji readings were not used in the anime series since they "might have cut down the laughs by about half".

Nevertheless, Konosuke Uda, fellow director, said that he believes that the creators "made the anime pretty close to the manga".

Unlike other manga artists, Oda draws everything that moves himself to create a consistent look while leaving his staff to draw the backgrounds based on sketches he had drawn.

This workload forces him to keep tight production rates, typically starting from five in the morning until two in the morning the next day, with short breaks only for meals.
