We introduced the Hobonichi Graph Notebook in 2019 in response to requests for a standard notebook that feels just like the Hobonichi Techo. The cover features a photograph of Denali, North America’s highest peak, as taken by Naoki Ishikawa.



This photo, capturing the full extent of Mount Denali at 6,190 meters above sea level, was taken from inside a Cessna heading towards base camp for the summit. The view of the mountain composed of deep blue and white looks like a watercolor painting at a glance. This photograph is processed with cyanotype, which is a photographic process that involves a chemical solution and exposure to UV light. The appeal in this design comes from the brush marks that let you see where the solution was applied.



The notebook has thin and durable Tomoe River paper and opens completely flat. 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.



The 3.7 millimeter graph paper is the same as that of the Hobonichi Techo Original. The color of the ink on the page changes (red / blue / green / purple) every 60 pages in the A6 size, and every 72 pages in the A5 size. This makes it easy to split the book into several themes or use the colors as a way to more easily find old entries.



Because the book sizes match the A6 Original and A5 Cousin Hobonichi Techos, you can use these notebooks with a techo cover. The cover is great for storing items like pens or sticky notes, and provides a very convenient user experience.



The notebook is a great supplement to the Hobonichi Techo, or simply a smaller-size notebook to keep by your side for filling with lots of writings or drawings.
