Hobonichi Techo: Complete Guide to Japan's Most-Loved Planner
If you've spent any time in the stationery community like I have, you've heard of the Hobonichi Techo. It's not just a planner. It's a cultural phenomenon. Designed by Japanese writer Shigesato Itoi and produced by Hobonichi Co., Ltd., the Techo has built a devoted following worldwide. In my opinion, that comes down to the exceptional paper, thoughtful layouts, and deep customization potential.
The secret sauce is Tomoe River paper: that impossibly thin, fountain-pen-friendly sheet that lets Hobonichi pack an entire year into a slim book without ghosting or bleeding. Every page is dated, every detail intentional. Whether you're a bullet journaler, a fountain pen enthusiast, or someone who just wants to get their life organized, there's a Hobonichi for you. I genuinely believe that.
In this guide, I'll walk you through every major Hobonichi Techo model: the Original, Cousin, Weeks, and 5-Year. Plus covers, accessories, and where to buy them.
The Hobonichi Lineup: Which Model Is Right for You?
Hobonichi Techo Original (A6)
Hobonichi Techo Original: A6 (1-Page-Per-Day)
The quintessential Hobonichi. The A6 Original is a compact 4.1" x 5.8" book with one full page per day. It's famously slim despite holding 365 pages of Tomoe River paper. The Original comes in a wide range of cover designs: from minimalist solid colors to wild collaborations with artists like Yoji Shinkawa and Katsuhiro Otomo.
Best for: Daily journalers, on-the-go planners, fountain pen users, and anyone who wants a lightweight year-long companion. The A6 fits in most handbags and jacket pockets.
Key specs: 4.1" x 5.8" (A6), 480 pages, Tomoe River S paper, monthly + daily spreads, quotes and illustrations throughout.

Hobonichi Techo Cousin: A5 (The Big One)
The Cousin is the A5 big brother. It's larger, more spacious, and beloved by those who need more room per day. I personally use the Cousin because I need that extra space. The daily pages offer a generous writing area with a vertical timeline on the left, which is Japan's standard hourly schedule. It's ideal for work planning, time blocking, and creative journaling.
One of the most requested features on the Cousin is the weekly supplement: a vertical weekly spread in the front that gives you a bird's-eye view of your week alongside the daily pages. This dual system is what makes the Cousin so powerful for productivity nerds like me.
Best for: Students, professionals, time-blockers, and anyone who wants more writing space. If you find the A6 too cramped, the Cousin is your answer.
Key specs: 5.8" x 8.3" (A5), 544 pages, Tomoe River S paper, monthly + weekly + daily spreads.

Hobonichi Techo Weeks: Mega & Standard
The Weeks is Hobonichi's horizontal weekly layout. It's a completely different beast from the Original and Cousin. Instead of daily pages, you get a week-on-two-pages spread that shows Monday through Sunday across facing pages. It's compact, lightweight, and perfect for glancing at your schedule.
The Weeks Mega adds a thicker note page section in the back with 196 memo pages (vs. 71 on the standard). For most people, the Mega is the sweet spot. You get the weekly layout plus serious note-taking capacity without moving up to the bulkier A6.
The Weeks also comes in an astonishing variety of cover designs, from classic leather-like covers to playful patterned fabrics. The MEGA editions tend to sell out fastest, so pre-ordering is recommended.
Best for: People who prefer a weekly overview over daily pages, students, busy professionals, travelers.
Key specs: 3.5" x 6.9" (slim), ~240 pages (standard) / ~365 pages (Mega), Tomoe River paper, weekly + monthly spreads.

Hobonichi 5-Year Techo: A6 & A5
The 5-Year is exactly what it sounds like: one book, five years, same date on each page. Each daily spread shows five panels, one per year. You can see what you were doing on March 14th across half a decade. I think it's a time capsule, a gratitude journal, and a fascinating exercise in self-reflection all rolled into one.
Available in both A6 and A5 sizes. The A6 is more popular, and I get why. The commitment is already large enough. A smaller form factor makes it easier to stick with. The paper is still Tomoe River, but the 5-Year uses a slightly thicker stock to handle the extra wear and tear of five years of use.
Best for: Long-term journalers, parents tracking childhood milestones, anyone who wants a daily snapshot of their life.
Key specs: A6 or A5, ~730 pages (10 panels per page for 365 days x 2 years per spread), Tomoe River paper.

One of the best parts of the Hobonichi ecosystem is the cover selection. Hobonichi sells a vast array of covers. You'll find everything from simple nylon zip cases to hand-stitched leather creations that develop a beautiful patina over years of use. The cover is reusable year after year. You just swap out the inner notebook.
A6 Original Covers
The A6 covers are the heart of the Hobonichi accessory line. Popular styles include the Liberty Fabrics collaboration (classic floral prints), the Bow Tie series (elegant, understated patterns), and the One Piece and Attack on Titan collaborations for anime fans. The A6 cover has a pen loop, two bookmark ribbons, and inner pockets for cards and receipts.
Cousin A5 Covers
The Cousin covers follow similar design principles but scaled up. The Leather A5 Cover is a perennial favorite. It's genuine leather, ages beautifully, and comes in rich brown, black, and burgundy finishes. The COC (Cover on Cover) clear plastic sleeve is a popular add-on to protect fabric covers from daily wear.
Weeks Covers
Weeks covers are designed for a slimmer profile. The Weeks Leather Cover is minimal and elegant, while the nylon zip covers offer more protection for travel. Many Weeks users skip the separate cover entirely and just use the one built into the planner itself (the "cover-with-a-cover").
Accessories
Don't miss the Hobonichi Pencil Board: a thin plastic sheet that sits under your writing page to prevent embossing and provide a smooth writing surface. The Stencil Ruler and Techo Stickers are also beloved by the community for adding structure and decoration to your pages. The Hobonichi Brass Stencil is a fan favorite for its weight and durability.
Paper Quality: Tomoe River S
Hobonichi uses Tomoe River S: the latest formulation of the legendary Tomoe River paper produced by Sanzen. It's 52 gsm, which is about half the weight of standard copy paper. Yet it handles fountain pen ink, brush pens, and even light watercolor with minimal ghosting. The paper has a unique coating that makes ink appear to pop with sheen and shading. If you're a fountain pen user, you'll understand the first time you write on it. I still remember mine. The feedback, the way the ink dries, the almost tactile pleasure of the nib gliding across the surface. It's something special.
Tomoe River S is ever-so-slightly different from the original Tomoe River, which was discontinued in 2020. It has slightly less coating. That means a bit less sheen but also less ghosting and faster dry times. Most users I've talked to, myself included, find it a worthy successor.
