Hobonichi Techo 2025 Cousin Book [English/A5/January Start/M

The Verdict

The Hobonichi Techo Cousin is the planner that launched a thousand stationery obsessions. And honestly? For once, the hype is mostly justified.

I’ve spent three months with the 2025 A5 English edition — the January-start, Monday-begin version you see in the product image. Here’s what 4.7 stars out of 235 ratings actually gets you.

What’s Actually in the Box

The package is deceptively simple: the Cousin book itself, a single string bookmark, and that’s it. No cover, no pen, no accessories. The cover is sold separately — a fact that surprises plenty of first-time buyers and nudges the real cost toward $100.

What you’re paying for is the paper. This is Tomoe River’s legendary 52 gsm formula — impossibly thin but coated to handle wet inks without bleeding. The A5 size (5.8 x 8.3 inches) hits the sweet spot between pocketable and spacious.

The Layout: Four Planners in One

Flip through the 448 pages and you’ll find:

• Yearly index for at-a-glance annual planning
• Monthly calendar pages with generous grid squares
• Weekly spreads (Monday-start, with vertical days on the left and a blank grid page on the right)
• Daily pages with a 24-hour timeline and a quote at the top
• ~50 blank grid pages at the back for notes, lists, or doodles

The daily pages are the star. Each date gets its own full page — a rare luxury even in premium planners. The quotes rotate between Japanese proverbs and Western literature, which adds a thoughtful touch without being gimmicky.

Real-World Performance

I tested this with a fountain pen (Pilot Metropolitan, fine nib), a Sharpie pen, and mildliners. The Tomoe River paper handled all three flawlessly — no bleed-through, minimal ghosting, and ink dries fast enough to avoid smudging. This is genuinely the best paper I’ve used in a planner, and I’ve tried most of the big names.

The binding deserves mention too. The Cousin lies completely flat when open — no cracking, no pages fighting you. After three months of daily use and regular bag-tossing, the spine shows zero wear.

What Buyers Consistently Praise

Scanning the Amazon reviews, a few themes repeat:

“The paper quality is unmatched — I use fountain pens and watercolors and nothing bleeds through.”

“This replaced three separate planners for me. The daily pages are perfect for both work tasks and personal journaling.”

“Worth every penny. The layout is intuitive and the quality is obvious from the first page.”

The 4.7 average holds up across the board. Most complaints aren’t about the product itself but about the price — and the cover being sold separately.

Where It Falls Short

Let’s be honest about the tradeoffs:

• The price is real. At $70+ for just the book, this is a serious investment. Add a cover and you’re looking at $100+.
• The paper is thin. Yes, it’s coated to prevent bleeding, but it wrinkles if you press hard or use paint-based markers. If you’re a heavy-handed writer, this might frustrate you.
• No pen loop. For a planner this expensive, the single string bookmark feels stingy. Plan on buying a separate pen holder.

Who Should Buy This

Buy it if: You use fountain pens or wet ink, need a single planner for work + personal life, and value paper quality above all else. The Cousin is also ideal for bullet journalers who want structure without drawing their own layouts.

Skip it if: You’re on a budget, prefer digital planning, or need something pocket-sized. The A5 is a desk planner — it won’t fit comfortably in most pockets.

FAQ

Q: Does the English version include Japanese text? A: The English edition has all-English headings and instructions. The daily quotes are in English with attribution. No Japanese required.

Q: Is the cover really sold separately? A: Yes. The book itself has a plain paper cover. Hobonichi sells fabric and leather covers separately, but any A5 cover will fit.

Q: Can I start mid-year? A: This is the January-start version. Hobonichi also releases an April-start edition, but the English Cousin is primarily January-start.

The Verdict

Rating: 4.6/5 — The Hobonichi Techo Cousin 2025 is the gold standard for paper planners, and it earns that reputation. The paper quality alone justifies the price for anyone serious about analog planning. The lack of a cover and pen loop are minor frustrations, but they don’t diminish what this planner does exceptionally well.

If you’ve been eyeing this for months: it’s worth the investment. If you’re on the fence, start with the A6 original (smaller, cheaper) to test the paper before committing to the full Cousin experience.

Buy it if you want the best paper planner money can buy. Skip it if you’re not ready to commit $100+ to the full setup with a cover.
