The Hobonichi Techo is legendary in the planner world, but it is not for everyone. Its A6 daily-page format demands a level of commitment that some people find overwhelming — an entire page per day can feel like too much space if your life does not fill it. That is where the Hobonichi Weeks comes in. Slim, compact, and brilliantly designed, the Weeks is Hobonichi’s answer to the question: “What if you love Hobonichi quality but prefer a weekly layout?”
We have used the Hobonichi Weeks as our primary carry planner for three years running. It lives in our back pocket, our jacket, our bag — wherever we go, the Weeks goes. It is the planner we reach for first, the one we open most often, and the one we recommend most frequently to people who want Hobonichi quality without Hobonichi bulk.
This review is based on years of daily use across multiple editions. We will cover the layout, paper quality, build construction, and everything else you need to know before committing to the Weeks as your planner.

Design and Size
The Hobonichi Weeks is designed around a single brilliant concept: a planner that fits in your wallet or back pocket. At 188mm x 95mm, it is roughly the same dimensions as a standard wallet — slim, elongated, and flat. You can slide it into a back pocket, tuck it into a jacket, or throw it in the smallest compartment of any bag. This portability is the Weeks’ greatest strength.
The slim profile comes from Hobonichi’s decision to use a weekly layout instead of daily pages. Where the standard Hobonichi Techo gives you one page per day (365 pages), the Weeks gives you one spread per week (52 spreads). This dramatically reduces the page count and thickness, creating a planner you can actually carry everywhere.
Hobonichi releases the Weeks in an extraordinary range of cover designs each year — typically 50 to 80 variations spanning solid colors, collaborative artwork, licensed characters, and premium materials. The standard covers are a smooth, durable plastic-like material that resists wear and cleans easily. The Weeks Mega variant adds additional notes pages (about 200 extra) for those who need more writing space, though it sacrifices some of the slim portability.
The binding is Hobonichi’s signature stitch binding, which allows the planner to lie completely flat when opened. This is essential for a planner this slim — any tendency to snap shut would make it frustrating to write in. The Weeks stays open obediently, and the spine is flexible enough to fold the planner back on itself if you need to write in tight spaces.
The Weekly Layout
The core of the Hobonichi Weeks is its weekly spread. The left page contains the week’s seven days in a vertical timeline format. Each day gets a rectangular block with the date, day of the week, and enough space for 3-4 lines of writing. The right page is entirely blank — a grid-free, line-free open space for notes, to-do lists, sketches, or whatever you need.
This left-right layout is elegant in its simplicity. The left page handles scheduling and time-based planning. The right page handles everything else. You do not need to decide in advance how to use the right page — some weeks it becomes a to-do list, other weeks a meeting notes page, other weeks a blank canvas for mind mapping or sketching. The flexibility is the point.
The daily blocks on the left page include a subtle time scale along the left edge (6 AM to midnight in some editions) that lets you block out appointments and events. The blocks are small enough to enforce brevity — you cannot ramble in a Weeks. Every word earns its space. For many users, this constraint is a feature, not a limitation. It forces prioritization and clarity.
Monthly calendars precede the weekly spreads, providing a bird’s-eye view of each month. These are compact but useful for tracking deadlines, events, and patterns. Many Weeks users write their big-picture plans in the monthly pages and their daily details in the weekly spreads.
Paper Quality
The Hobonichi Weeks uses Tomoe River S paper at 52gsm — the same extraordinary paper found in the standard Techo. This paper is legendary in the stationery world for its thinness, smoothness, and ink-friendliness. At 52gsm, it is thinner than standard copy paper (80gsm) yet handles fountain pen ink, gel pen ink, and even watercolor without bleeding through.
Writing on Tomoe River paper is a pleasure. The smooth surface allows pens to glide effortlessly, and the paper resists feathering (ink spreading along paper fibers) better than almost any other paper available. Fountain pen enthusiasts particularly love Tomoe River because it showcases ink properties like shading and sheen that are invisible on ordinary paper.
The trade-off for this thinness is show-through — you can see writing from the reverse side as a shadow. This is not bleed-through (the ink does not soak through to the other side), but the visual presence of reverse-side writing is noticeable. Most Weeks users adapt quickly and stop noticing it, but if show-through bothers you, consider using only one side of each page or choosing lighter ink colors.
Dry time on Tomoe River is slower than on standard paper. Gel pen ink can take 10-15 seconds to fully dry, and fountain pen ink may take 20-30 seconds. We recommend waiting a moment before closing the planner to avoid smearing. Quick-drying inks like the Uni Jetstream ballpoint avoid this issue entirely.
How We Use the Hobonichi Weeks
After three years, we have developed a system that works well for us:
Monthly pages: Major deadlines, travel dates, and recurring events. We write these in at the beginning of each month using a fine-tip pen.
Weekly left page: Daily tasks and appointments. We write 2-3 key tasks for each day, along with any time-specific appointments. We use a simple bullet system: open circle for tasks, filled circle for completed, arrow for migrated.
Weekly right page: This varies by week. Common uses include meeting notes, weekly goals, shopping lists, project brainstorming, and quick sketches. Some weeks this page is packed; others it stays mostly empty. Both are fine.
Notes pages (back section): Long-term reference information. Phone numbers, addresses, book recommendations, gift ideas, restaurant lists — anything we want to carry with us and reference occasionally.
This system works because the Weeks does not try to impose a rigid structure. It gives you just enough framework (the weekly timeline) and just enough freedom (the blank right page and notes section) to build your own system organically.
Hobonichi Weeks vs. Hobonichi Techo
The most common question we hear: “Should I get the Weeks or the Techo?” Here is how they compare:
| Feature | Hobonichi Weeks | Hobonichi Techo (Original) |
|---|---|---|
| Size | 188 x 95mm (wallet) | 148 x 105mm (A6) |
| Layout | Weekly spreads | Daily pages |
| Pages | 240 | 464 |
| Weight | ~100g | ~200g |
| Portability | Excellent (fits in pocket) | Good (fits in small bag) |
| Writing Space | Moderate | Extensive |
| Paper | Tomoe River S (52gsm) | Tomoe River S (52gsm) |
| Best For | Scheduling, portability | Journaling, detailed planning |
Choose the Weeks if: You want a portable, low-commitment planner that handles scheduling and basic note-taking. You prefer brevity over detail. You want something you can carry everywhere without thinking about it.
Choose the Techo if: You want extensive daily writing space for journaling, detailed planning, or creative use. You do not mind carrying a slightly larger planner. You want to fill a page per day. Read our full Hobonichi Techo review for more details.
Choose the Cousin if: You want daily pages in a larger A5 format. See our Hobonichi Cousin review.
Pen Compatibility
We have tested dozens of pens with the Hobonichi Weeks and can recommend the following pairings:
Best Pens for the Weeks
- Pilot FriXion Slim 0.38mm: Erasable, ultra-fine, fits the pen loop. Our top pick for the Weeks.
- Uni Jetstream 0.5mm: Quick-drying ballpoint that eliminates smearing concerns. Excellent for fast writing.
- Pilot Hi-Tec-C 0.4mm: Ultra-fine gel pen with crisp, precise lines. Beautiful on Tomoe River paper.
- Platinum Preppy EF: Budget fountain pen that writes beautifully on Tomoe River. The EF nib fits perfectly in the small daily blocks.
Pens to Avoid
- Broad-tip markers: The daily blocks are too small for thick lines.
- Heavy-flow fountain pens: Wet writers can cause excessive show-through on 52gsm paper.
- Slow-drying gel pens: The Weeks’ slim format means pages rest against each other, increasing smear risk.

Pros and Cons
Pros
- Exceptional portability — genuinely fits in a pocket or wallet
- Tomoe River S paper — premium paper quality in a compact planner
- Flexible layout — structured weekly + open notes page
- Lies flat when opened, easy to write in
- Massive cover selection — dozens of designs each year
- Notes section provides additional reference space
- Monthly and yearly overview pages included
Cons
- Limited daily space — only 3-4 lines per day
- Show-through on thin Tomoe River paper

The Weeks Mega
For users who love the Weeks format but need more writing space, Hobonichi offers the Weeks Mega. It adds approximately 200 additional notes pages to the back of the planner, roughly doubling the total page count. The extra pages use the same Tomoe River S paper and are blank (no grid or lines).
The Mega is noticeably thicker than the standard Weeks, which partially defeats the purpose of the slim design. However, it is still more portable than the standard Techo, and the extra pages are invaluable for meeting notes, journal entries, and reference information. We used the Mega for one year and found the extra pages useful, but we ultimately returned to the standard Weeks because we preferred the slimmer profile.
Who Should Buy the Hobonichi Weeks?
Minimalist planners. If you believe the best planner is the one you actually carry, the Weeks wins. Its pocket-size format means it is always with you, which means you actually use it.
Schedule-focused users. If your planner’s primary job is tracking appointments, deadlines, and daily tasks (rather than extensive journaling), the Weeks provides exactly enough space without excess.
Hobonichi-curious users. If you are interested in Hobonichi but intimidated by the commitment of a daily-page planner, the Weeks is the perfect entry point. Same paper quality, same design philosophy, less pressure.
Travelers. The Weeks’ slim profile makes it ideal for travel, where bag space is limited and you want something you can pull out on a train, at a cafe, or in an airport without unpacking a full planner setup.
Frequently Asked Questions
Is the Hobonichi Weeks worth the price?
At roughly $22-30 depending on the cover, the Weeks is more expensive per page than most planners. However, the Tomoe River paper, the quality of the binding, and the thoughtful layout justify the premium. We have used planners at every price point, and the Weeks provides the best combination of quality and portability. It is worth the investment.
Can I use fountain pens in the Hobonichi Weeks?
Yes. Tomoe River paper is excellent for fountain pens — it resists feathering and bleeding, and it showcases ink properties beautifully. Use fine or extra-fine nibs to manage show-through, and give the ink a few extra seconds to dry before closing the planner.
Does the Hobonichi Weeks start in January or April?
The standard Hobonichi Weeks runs from January to December. Hobonichi also releases an April-start edition for the Japanese academic and fiscal year. Both versions are available internationally through the Hobonichi store and Amazon.
How do I choose between the Weeks and the Weeks Mega?
If you primarily use the Weeks for scheduling and brief notes, the standard Weeks is sufficient. If you want to use it for more extensive note-taking, meeting notes, or journaling alongside your scheduling, the Mega’s extra 200 pages are worth the slightly thicker profile.
What accessories work with the Hobonichi Weeks?
Hobonichi offers official Weeks accessories including clear covers (for protecting the planner while showing the cover design), pen clips that attach to the cover, and sticker sets designed for the Weeks’ layout. Third-party accessories include slim pen cases, bookmark ribbons, and custom dashboards.
Final Verdict
Rating: 4.5/5
The Hobonichi Weeks is the best wallet-size planner we have ever used. It combines Hobonichi’s legendary Tomoe River paper with a practical weekly layout in a form factor that genuinely fits in your pocket. The constraint of limited daily space is, paradoxically, its greatest strength — it forces clarity and prioritization while providing just enough flexibility through the blank right page and notes section.
The Weeks loses half a point for the inherent limitations of Tomoe River paper (show-through and slow drying) and the lack of a pen loop on standard covers. But these are minor complaints about an outstanding planner that we have used daily for three years and plan to use for many more.
If you want a planner that goes everywhere you go — no excuses, no forgetting, no leaving it at home because it is too bulky — the Hobonichi Weeks is the answer.
