This is a Japanese version, 2026 Spring Hobonichi Techo Cousin book in A5 size. 
April / Monday start planner. 

The layout is a day-per-page. 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. Like with the Japanese version, each month is printed in a different color.

The daily pages include a quote in English per two-page spread specially chosen from the Hobonichi website.
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.
