How to Choose a Japanese Notebook

A Japanese notebook is rarely the flashiest thing on the shelf. The covers tend to be quiet — brown card, a stamped border, a plain cloth spine — because the money has gone into the paper. That's a trade we're happy with, and it's why choosing one is less about looks and more about four practical questions: how heavy the paper is, how the page is ruled, what size suits the way you carry it, and how the thing is bound. Work through those in order and the right notebook mostly picks itself.

Start with the paper, not the cover

Paper weight is measured in gsm — grams per square metre. Ordinary office paper sits around 80gsm, and plenty of Japanese notebook paper actually runs lighter than that, which surprises people. The number matters less than you'd think, because Japanese mills put as much work into coating and fibre as into thickness. What the weight hints at is show-through: bleed-through is ink soaking clean through the sheet, while ghosting is the faint shadow of writing you can see from the other side. Bleed-through ruins the back of every page. Ghosting is cosmetic — some writers never notice it, and some can't unsee it.

The famous outlier is Tomoe River, the paper that became a kind of holy grail among fountain-pen users because it breaks the rule: unusually thin, almost translucent, yet it holds wet ink without bleeding through. The Tomoe River 68gsm softcover notebook by SAKAE uses the heavier of the two Tomoe River weights — a touch more substance under the nib than the original 52gsm — bound into 160 pages behind a cloth spine and a stamped Art Nouveau border. One honest caveat: ink takes a beat longer to dry on it, which left-handed writers will want to weigh up.

Rulings: ruled, grid or dot

Ruled lines are the traditional choice, and few makers have more history with them than LIFE, a Tokyo stationery company that has been producing fountain-pen-friendly paper since 1949. Their Noble Note A5 is the ruled workhorse of the range — 100 sheets of smooth, faintly cream paper under a restrained brown-and-cream cover. It looks like something your grandfather might have kept ledgers in, and we mean that as a compliment.

Grid ruling suits anyone who mixes writing with sketches, tables or lists. Kleid's Tiny Grid Notes B6 takes it further than most: a 2mm grid printed on OK Fools bookbinding paper. We'll admit 2mm sounded too fine to be usable before we tried it. In practice the grid reads as texture rather than lines — it disappears behind handwriting and reappears the moment you need to rule a box or keep a margin straight. It has quietly become our favourite ruling in the shop.

Dot grid splits the difference, giving you structure without visible lines. The SAKAE comes in a 5mm dot grid or plain, if you'd rather the page stayed out of your way entirely.

B6 or A5: choose by how you carry it

A5 — 148 × 210 mm, the size of the LIFE — is the desk standard: room for a full day of notes, minutes and proper margins. B6 is a step smaller and the size we'd nominate for anything that travels; it slips into a bag pocket without folding its corners. The Kleid is B6 and just 32 pages, which sounds slight until you realise a slim notebook is one you actually finish. Retiring a completed notebook is a far better feeling than abandoning a half-empty 200-page block. The SAKAE is made in both A5 and B6, so you're not forced to choose between the paper and the format.

Binding: thread-stitched or stapled

Binding decides whether a notebook opens flat, and that matters more than it sounds — a book that fights your writing hand near the spine ends up left in a drawer. Thread-stitched binding, where sections of paper are sewn together, is the mark of a properly made Japanese notebook. Kleid leaves the stitched spine exposed, an old bookbinder's trick that lets the book open completely flat, and the SAKAE's thread binding does the same job behind its cloth spine. Stapled notebooks are lighter and cheaper, perfectly fine for short-lived jotters, but they won't lie flat once you're past the centre pages.

Small extras live here too. The Kleid's pages are perforated for clean tear-out — useful when half of what you write ends up handed to someone else.

Matching a Japanese notebook to your pen

The quickest way to shortlist a Japanese notebook is to look at the pen already in your hand. A fine gel pen — a 0.38 or a 0.5 — is forgiving and will behave on nearly every paper above, so ruling and size matter more than gsm; our guide to Japanese gel pens covers that side of the equation. A fountain pen raises the stakes: wetter lines, more ink sitting on the page, and pigment inks that dry differently again — we've unpacked that in pigment vs dye fountain pen ink, explained. For fountain pens we'd go straight to the Tomoe River or the LIFE rather than gamble on unproven paper.

Where we'd start

For an everyday gel-pen notebook, the Kleid Tiny Grid. For fountain pens, the SAKAE with its Tomoe River paper. For a classic ruled A5, the LIFE Noble Note. And if none of those quite fits, the rest of our notebooks and planners follow the same logic we've laid out here — paper first, cover second.

Paper first. Everything else follows.
