Select shop and brand Arts&Science owner Sonya Park directed the creation of this English-language Hobonichi Techo book, which has been refined and simplified to make it easy to use in all countries and languages. The refined layout, the color scheme of charcoal gray and red, and the bonus pages exclusive to the Planner are part of its charm.
The book has a matte cover subtly foil-pressed with the Japanese characters for “techo” alongside the Arts&Science key logo.
The book spine is foil-pressed in gold with the year 2027 and the “HOBO” logo for easy reference when placed in your bookshelf alongside other books.
Like a dictionary, this techo is made with thread-stitched binding. This allows it to open flat at 180 degrees, making it easy to write in — no need to hold the pages down.
The pages are made of thin and light yet durable Tomoe River paper that holds ink well, providing a smooth writing experience.

The back of the techo contains bonus pages, including standard favorites such as International Size Charts, and the Ultimate Packing List, My 100, as well as new additions like the Japanese Sando - Sandwiches for Every Occasion, Hard-to-Translate Japanese Words, and the Hobonichi’s Neighborhood: Kanda/Jinbo-cho Map.
The Hobonichi Techo is designed to be used with a cover. In addition to techo covers created in collaboration with Arts&Science, we offer a wide range of dedicated techo covers to choose from. Explore the different colors, materials, and designs to find your perfect match.

The Tomoe River paper designed for planners is known for its thinness and smooth writing surface. However, depending on the type and amount of ink or pen used—as well as environmental conditions—some ink may bleed through or take longer to dry. We recommend testing your pens on an inconspicuous area first, or using a pencil board or blotting paper for best results.
