HobonichiHobonichi Lined NotebookA6 Size / A5 Size
- 2025 New
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.
We’d love to help kids get out of their study slumps, and help adults concentrate with a notebook that’s comfortable for their eyes. That’s the wish that brought about this ruled line design that focuses on reducing eye strain and based on design psychology.
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. 
The design is soft with lines that aren’t too overbearing, so the notebook doesn’t feel menacing when you open it and doesn’t tire your eyes over a long writing session. It also allows you to smoothly write out words and charts. The result was a design, patented in 2020, that’s never been tried before. 
The height of the lines are narrowed down slightly from the Hobonichi Note to match the size of this notebook.
This notebook is easy to use when you want to focus on your studies or thoughts. 
It comes in two sizes: A6 to match the Original, and A5 to match the Cousin. The A6 size notebook is 8mm thick and contains 240 pages, while the A5 size is 10mm thick and contains 288 pages. This gives you plenty of space to fill the notebooks to your heart’s content. Because the book sizes match the A6 Original and A5 Cousin Hobonichi Techos, you can use these notebooks with a techo cover.
We have the graph paper-type Hobonichi Graph Notebook and the blank Hobonichi Blank Notebook in the same sizes.

- Test fountain pens before regular use
The Hobonichi Techo's Tomoe River paper is designed to prevent bleed-through, but some fountain pens and water-based ink pens are not compatible with this paper. When switching to a new pen, we recommend testing the pen somewhere in the book, such as the back memo pages, to see if the ink bleeds through or takes an especially long time to dry.
