Hobonichi Techo 2025 Japanese Cousin Book (April Start) - A5

A5 Size / Daily / Apr start / Mon start

The Hobonichi Techo Cousin Book is an A5-sized techo with ample writing space, featuring one page per day. This April-start version starts in April 2025 and covers through March 2026.

Not only is it useful for writing down your plans for the day, jotting down memos, doodling, pasting event tickets or photos, the spacious Cousin is easy to use as a techo to write down everything work-related, as a family notebook, tracking the growth of children and pasting in pictures to create a family album or sharing pages among family members. It’s also frequently used as a planner that is always kept on a desktop or table rather than carrying around.

After years of testing, the graph paper has been set to 3.7 mm for optimal writing comfort. The graph paper design allows users to write from any starting point on the page, and the lines have been printed in light colors so users can either customize it to their own layout or ignore it completely.

The Hobonichi Techo includes quotes specially chosen from its parent site, the Japanese web magazine Hobo Nikkan Itoi Shinbun. Each daily page has a quote in Japanese.

The Cousin also has an exclusive section: the popular weekly pages track a week in each two-page spread for easy planning and contain a handy time schedule.



The book has the same thread-stitch binding as a dictionary, allowing it to lay flat open for comfortable writing. 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.



Other than the daily pages with lots of space to write, the book contains several sections that are great for schedule management, such as a yearly calendar, monthly calendar, and yearly index page. The back of the book has bonus pages, including Sample Symbols and Icons, How to Have Fun Keeping a Diary, and Recommended Noodle List of 47 Prefectures.




The Hobonichi Techo is used by pairing a techo book with a cover. Pick out a cover of your choice from our large selection of convenient A5 size Hobonichi Techo covers.



We also have the Hobonichi Pencil Board fitted for the A5 Cousin size. Not only does it keep pens from slipping and makes writing more manageable, but it also serves as a bookmark for the page that you are writing. It’s a standard item that would excellently match your techo.

Test fountain pens before regular use

When using fountain pens or water-based ink pens, depending on the environment, you may notice smudging, bleed-through, or slow drying of the ink. We recommend testing the pen somewhere in the book beforehand, such as the back memo pages, before use.
