Slash is one of the basic design options for the HON, which has a hardcover design already attached to the book. The dark navy cover almost looks black, and the diagonal slash is foil-printed in gold.

The design is based on the forward-slash symbol ( / ) used when writing dates. The cloth of the cover has a matte texture that feels nice in your hands and is resistant to grime, as well as wear and tear.

The book spine is foil-pressed in gold with the year 2025 and the HON logo for easy reference when placed in your bookshelf alongside other books.

The contents are the same as the Hobonichi Techo Cousin book. The HON A5 size includes weekly pages which track a week in each two-page spread for easy planning and contain a handy time schedule.

The bookbinding on the HON has thread-stitch binding similar to the Hobonichi Techo Original, so it opens 180 degrees onto the table. It stays flat even if you don’t hold it down.

The book uses thin and light yet durable Tomoe River paper. This paper that underwent an overhaul with the 2024 edition techo is more resistant to bleed through, lighter despite being the same thickness, and has a smoother surface by adjusting the fibers of the paper.

The back of the book has bonus pages, including Sample Symbols and Icons, How to Have Fun Keeping a Diary, and Oodles of Noodles.

As a special exclusive only for the HON, this techo comes with a pencil board. The board is A6 size and clear, with 5mm grid lines printed across it. There are measurements printed along one side in 1mm increments, which allow for use as a ruler. It also has a pen holder attached to it where users can store pens by their clips.
