LIFE and IDEA booklets can be added separately; KOKUYO's global store lists the 2027 Biz as made in Japan. What is the KOKUYO Jibun Techo Biz?
It is the Jibun Techo dressed for the office. KOKUYO describes it as keeping the 24-hour axis of the weekly vertical page and the monthly block, in a calmer color scheme and font that suit business. If you know the Standard DIARY, the layout is the same; the changes are the look, the paper and the cover.
What is on the pages?
A year of planning pages plus lists. KOKUYO lists these contents:
Section
Pages
Calendars and plans
3-year calendar, annual schedule, monthly block, monthly project, weekly vertical
Goals and money
Dreams and goals for this year, financial planning, 100 things to do this year, looking back at this year
Lists
Book list, movie list, gift lists, promise list, recommendation list, free list
Reference
Age chart, map of Japan, favorite words, personal data
Why does the paper matter?
MIO PAPER is the Biz’s main difference from the Standard. KOKUYO says it dries ink quickly, resists show-through, has enough stiffness to turn comfortably and lies flat even near the binding. The Standard DIARY uses THIN PAPER, which KOKUYO describes as thin, light and wrinkle-resistant under an erasable ballpoint.
What is the cover like?
Matte, opaque and practical. The cover does not show through, has a wide pen holder that takes thick multi-color pens, and has pockets and slits for cards and business cards.
What sizes and prices are there?
Two sizes, with or without a cover. KOKUYO lists these 2027 prices, all starting in January:
Version
Size
Listed price
Matte black, matte navy or light beige
A5 Slim
4,300 yen (about US$27.22)
Matte black or light beige
mini B6 Slim
3,900 yen (about US$24.68)
DIARY refill, no cover
A5 Slim
3,900 yen (about US$24.68)
DIARY refill, no cover
mini B6 Slim
3,700 yen (about US$23.42)
By our arithmetic the cover costs 400 yen over the refill in A5 Slim and 200 yen in mini.
Can you add LIFE and IDEA?
Yes, for the Biz and Standard only. The LIFE booklet and the IDEA notebook are sold separately and can be set in; they cannot go in the Lite or DAYs .
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?
Japan, per KOKUYO’s global store. The A5 Slim cover version at 4,300 yen (about US$27.22) 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.
