A Weeks in collaboration with ONE PIECE magazine, a publication which dives deep into the world of the manga One Piece. This design combines several scenes taking place during the adventures in the Drum Kingdom—a fan favorite arc within the One Piece series.

The hard cover comes in a light gray, and it’s made to be durable, yet slightly flexible. The year 2026 is foil-pressed in silver.

Woven into this shiny necktie weave is a crying Tony Tony Chopper, saying, “I will make myself the miracle cure!!! I will become the doctor who can cure everything!!!” as he waves Dr. Hiriluk’s pirate flag...

The book uses thin and light yet durable Tomoe River paper. It's characterized by its ability to hold ink well and provide a smooth writing experience.

The Weeks book has space for writing in plans or journal entries, and it also has 71 pages of grid paper memo pages in the back (75 pages in the English edition). The back of the book contains bonus pages, including Memories 2026 and 12 Switches to Help You Focus.
