What “Hobonichi Techo” means
Hobonichi Techo is a planner notebook made by staff of the website Hobo Nikkan Itoi Shinbun. Hobonichi is that site name shortened, and techo — pronounced “tetch-oh” — is a Japanese word for a planner notebook. Hobonichi’s own first-time guide also calls the book a Life Book: a dated notebook with open space, meant to fit different ways of planning rather than one fixed method. The 2019 English explainer is the clearest official statement of the name: What is the Hobonichi Techo?
The name does not point to a single size. Long-running examples are the A6 Original (one page a day), the A5 Cousin (one page a day, plus a weekly section only the Cousin has), and the slim Weeks (one week on a spread, with memo pages). Those three are examples, not the whole lineup. Hobonichi also sells a five-year techo, a Day-Free book that pairs a monthly calendar with graph-paper notes, and English-language books, including the A6 Planner. Most books are paired with a separate cover; many Weeks books include a cover. The 2023 overview already listed more than three types, and the current 2026 type guide still does.
The paper is part of the product. Official pages describe thin, light Tomoe River paper, and the daily books use stitch binding that lies flat. English editions are language versions, not automatically a reduced book: the 2026 English Cousin page says its layout matches the Japanese edition, while the English Planner is a separate January-start A6 book with Monday-start weeks. Confirm the year’s type page before assuming an edition difference.
Three common sizes, not the whole lineup
Hobonichi’s catalog is wider than a three-way choice. If you are comparing the books people usually mean by “the Hobonichi,” these are the useful starting points. Everything else — five-year, Day-Free, April-start, Avec split books, language editions — is a separate type, not a variation of these three.
- Original (A6): the classic daily book. Compact, one page a day, and paired with a cover. Hobonichi describes it as the standard book in the lineup.
- Cousin (A5): the largest daily book, with room to write and paste, plus a Cousin-only weekly section. The 2026 type page gives the size as 148 mm × 210 mm.
- Weeks: a slim weekly book. One week is visible on a spread, with blank memo pages. It is light by design; that is a product description, not a claim about who uses it.
Choose by the page you will actually fill, not by how the book looks in a photograph. The Original is the pocket-scale daily page. The Cousin is the large daily page. The Weeks is the weekly page.
The paper is a stated product feature
Hobonichi attributes the book’s thickness to Tomoe River paper: thin and light enough for a long daily book to stay compact, and described as comfortable to write on. That is the official reason a one-page-a-day Hobonichi can be hundreds of pages. Paper behavior with a specific pen still depends on the ink and the year’s paper; the type pages do not promise zero bleed for every fountain pen.
English editions are language versions
Do not treat “English” as one book, or as a store-stock story. As of the 2026 type pages checked on 2 October 2026:
- The English Cousin is described as the same book layout as the Japanese Cousin, with an English quote on the daily pages.
- The A6 Planner is the English daily book. It is January-start only, uses Monday-start calendars, and shares covers with the A6 Original.
- Weeks is sold in Japanese and English editions. Page counts and bonus pages differ by edition; read the current product page rather than a general rule.
A Japanese daily page is mostly dates, a grid, and a quote. Whether that is usable if you write in English is a personal fit question, not something this page can settle from a store shelf.
Which one should you buy?
Match the book to the page layout you want:
- A pocket-size page for each day → Original, or the English Planner if you want the A6 book in English.
- A large daily page plus a weekly timetable → Cousin.
- A week on one spread, and a thinner book → Weeks.
If none of those is the job — a five-year memory page, or a monthly calendar plus blank notes — look at the 5-Year Techo or Day-Free on the current type guide instead of forcing the choice into three. Covers change every year; the book type is the decision that has to fit.
