The Hobonichi Techo HON is the hardcover version of the Original and Cousin planners, available in A6 and A5 respectively. Its contents are the same as the Hobonichi Techo Original and Cousin with daily pages covering January 1 to December 31 and has Japanese quotes on the bottom of the page. It also includes the same yearly calendar, monthly calendars, yearly index, weekly layouts for the A5, and bonus pages.

The HON can be used without a cover and is just like a book. A hardcover design is already printed and adhered to the book, making it more compact and easy to carry around than putting a cover over an Hobonichi Techo Original or Cousin.

Just like the Hobonichi Techo Original and Cousin, the HON uses the same lay-flat stitch binding method and opens to 180 degrees so you can write in it without having to hold the pages down.

The HON has two attached bookmarks—one navy and one beige—so you can mark your place in frequently used pages. Included with every HON is a transparent pencil board that has a pen loop attached. Use the pencil board as an underlay to have a flat writing surface on every page, or as a bookmark to keep your place in any part of the book.
