Hobonichi Techo 2026 Japanese Cousin Book [A5/Jan Start/Mon Start]

The Hobonichi Techo Cousin is an A5 size planner with a page-per-day format. January 2026 start. Japanese edition.

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 colours so users can either customise it to their own layout or ignore it completely.

The Hobonichi Techo includes quotes specially chosen from the Hobonichi website. Each daily page has a quote in Japanese.

The book uses thin and light yet durable Tomoe River paper. It’s characterized by its ability to hold ink well and provide a smooth writing experience.
