2025 Hobonichi Accessories: A5 Lined Notebook

We now have a new addition to the notebooks you can use with the Hobonichi Techo. This notebook has thin and durable Tomoe River paper and opens completely flat.

The ruled lines used are the same that are used in the Hobonichi Note. The ruled line design was developed by Prof. Haruo Hibino and his team of researchers at BB STONE Design Psychology Unit, Inc., a venture company of Chiba University’s Faculty of Engineering.

The ruled paper is unique in that the horizontal lines crossing the page are interrupted by short vertical lines that form a subtle grid. However, they perceptually look like straight lines, because of an optical illusion caused by the way our brains work.
