Hobonichi - Kyohei Sakaguchi: A Notebook to Help Me Remember

This A5-sized notebook, designed by artist Shun Sakaguchi, is a beautifully minimal tool for free writing, thinking, and creative exploration. Its clean format and thoughtful details make it ideal for those who value quality paper and quiet design.

The notebook contains 288 pages of Tomoe River paper—a lightweight yet durable paper that offers an exceptionally smooth writing experience, even with fountain pens. The thread binding allows the notebook to open completely flat (180°), making it comfortable to use on any surface.

Each page features a 5 mm grid, slightly larger than that of the Hobonichi Techo, printed in a gentle sky-blue tone. The grid provides subtle guidance without interfering with your writing or drawing, allowing for both structured and free-form layouts.

Whether used as a journal, idea book, sketchpad, or everyday planner companion, this notebook adapts to your routine with elegance and simplicity.
