Hobonichi × ONE PIECE

The Hobonichi × ONE PIECE collaboration has always taken the Straw Hat Crew rather more seriously than a planner strictly needs to. Each release is made with ONE PIECE magazine, so the covers and accessories feel less like merchandise and more like pages from a working sketchbook: Luffy drawn over pale storyboard lines, a Jolly Roger woven into an orange hardcover, the Going Merry embroidered on black fabric.

Here you will find the 2027 Weeks, HON and A6 Original Book, A6 and A5 Cousin covers, pencil boards, sticky notes, stickers and pouches, alongside the last of the 2026 range. The fabric covers soften with handling, the pencil boards sit flat and cool beneath your pen, and none of it asks you to be a collector to enjoy it. A diary is, after all, simply a log of the voyage. This one happens to come with a crew.
