What is the Hobonichi Techo Planner 2027?
The Planner is Hobonichi’s English-language A6 page-a-day book with a simplified layout designed by Sonya Park of Arts&Science. Hobonichi describes it as refined to be easy to use in any country and language, with a charcoal-gray and red color scheme and bonus pages of its own.

A 4 mm square is about 8% wider than a 3.7 mm one.
The larger grid suits people who write bigger or who found the Original’s grid fussy. The cover is matte, foil-pressed with the Japanese characters for “techo” and the Arts&Science key logo, and the spine carries 2027 and a HOBO logo in gold.
What is on each daily page?
Each day has its own page with the date, a 4 mm grid, a moon phase and a mini monthly calendar on every two-page spread. Hobonichi also lists the day of the year and the week number.
A page at the start of each month helps you plan ahead, and a blank spread at the front gives a free area as you start the book. Bonus pages include international size charts, an ultimate packing list, My 100, Japanese sandwiches, hard-to-translate Japanese words and a map of Hobonichi’s Kanda and Jinbocho neighborhood.
Is the Planner good for fountain pens?
It uses the same thin Tomoe River planner paper as the Original, so fine nibs work best. Hobonichi warns that depending on the ink and pen, writing can bleed through or dry slowly, and suggests a pencil board or blotting paper.
Choose the Planner for a cleaner English layout and a bigger grid, the Original for the classic design, and the Original avec for two lighter half-year books. All three are A6 and take the same covers. If you want weekly pages, look at the Hobonichi Cousin instead.
Where is the Hobonichi Planner made?
Hobonichi doesn’t state where the Planner book is made, so we list it as “Not stated”. The store page names a country only for a free bonus charm (China). Hobonichi Co., Ltd. is a Tokyo company; check the back of your book.
