Quick answer The KOKUYO Jibun Techo DAYs is a one-day-per-page planner with the 24-hour axis down the middle, so work and family or to-dos and life log can sit on opposite sides. A patented row of dates and weekdays shows where the day falls in the week. It uses THIN PAPER and the A5 Slim costs 5,000 yen (about US$31.65).
The DAYs closed, open on two day pages, and the mini in pink (1 mm = 1 px). Original illustration made for this guide. © Stationery Times.

Price: example listing . How we test and disclose samples: How we test stationery . Price bands are typical US retail, checked October 2026. Conversions to US dollars are approximate, at October 2026 rates (US$1 = ¥158 = ₩1,330 = NT$32.5 = CN¥6.7 = SEK 9.9 = DKK 6.7 = ₺49.6 = C$1.41 = A$1.43 = CZK 21.7; €1 = US$1.12; £1 = US$1.32; CHF 1 = US$1.21). Key takeaways One page per day, with a 24-hour axis in the middle so the left and right halves can hold different things. A patented horizontal strip of dates and weekdays shows the day's place in the week, which KOKUYO says fixes the usual weakness of daily planners. THIN PAPER is thin, light, resists bleed-through and does not wrinkle under an erasable ballpoint, per KOKUYO. Listed prices: A5 Slim 5,000 yen (limited sheep-pattern 5,600 yen); mini B6 Slim 4,400 yen (limited 4,800 yen). LIFE and IDEA cannot be set into the DAYs; KOKUYO's page gives no country of manufacture. What is the KOKUYO Jibun Techo DAYs?
It is the one-day-per-page Jibun Techo. KOKUYO describes a design with the 24-hour axis in the middle of each page, so you can write different things on the left and right: work and family schedules, or a to-do list and a life log. It is the only Jibun Techo line built around a daily page.
How does it solve the daily planner problem?
With a strip of dates and weekdays. KOKUYO says the weakness of a one-page-per-day planner is that it is hard to see where a day falls in the week. A horizontal row of dates and weekdays on each page fixes that, and the company says this is patented.
What is in it?
Monthly pages with a habit tracker, then daily pages. KOKUYO lists:
Section
Pages
Calendars
3-year calendar, annual schedule, monthly block with habit tracker, monthly front page
Goals
This year’s goals, this year’s events, money plan, 100 things to do this year
Daily and notes
Daily pages, free list (6 pages), memo pages (11 pages), looking back at this year
What paper does it use?
THIN PAPER. KOKUYO says it is thin and light yet does not bleed through, and does not wrinkle even when rubbed with an erasable ballpoint pen. That makes it a match for Pilot FriXion pens.

Can you add LIFE and IDEA?
No. KOKUYO says the LIFE and IDEA booklets cannot be set into the DAYs. They fit the Standard and Biz only.
How does it fit the Jibun Techo family?
It is one of seven lines that share a design. KOKUYO’s series page lists the Standard, Biz, Lite, DAYs and First Kit planners plus the LIFE and IDEA booklets. It says the Jibun Techo was developed over many years by an advertising creative and won a Good Design Award in 2014, and that pairing LIFE and IDEA with the DIARY is meant to turn a one-year book into one for life. Our guide to the 2027 edition says it went on sale from mid-September 2026.
Where can you buy it?
KOKUYO points to its own and big retail shops. The series page links KOKUYO’s official online stationery shop, Amazon, Rakuten, Kaunet and KOKUYO’s official global online store. Prices on this page are the yen prices on KOKUYO’s series page at 158 yen to the dollar, so overseas retailers will charge more.
Where is it made, and what does it cost?
KOKUYO’s series page doesn’t say. The A5 Slim gray at 5,000 yen (about US$31.65) is in our $$$ band ($20–75).
Our KOKUYO Jibun Techo 2027 DIARY guide covers the Standard book, the First Kit guide covers the three-book set, and Hobonichi Techo vs Jibun Techo compares the two planner families.
