Every few weeks someone writes to this site with a version of the same question: I don’t have room for ink and paper. Can I learn Japanese calligraphy with a brush pen?
The honest answer is partly — and the part that works is more useful than most calligraphers admit.
A brush pen (筆ペン, fude pen) is a Japanese invention from the 1970s: a pen body with an ink reservoir and a brush-shaped tip, either a flexible felt point or a bundle of real synthetic bristles. In Japan it is an everyday object. It is what people use to write their name on a wedding envelope, address a New Year’s card, or sign a condolence book — situations that call for brushwork but not for grinding ink at the kitchen table. Millions of Japanese adults own one; a minority own a real brush.
For a beginner overseas, that everyday quality is exactly the point. A brush pen fits in a pencil case, writes on printer paper, dries in seconds, and costs less than a cup of coffee. It cannot teach you everything a brush teaches. It can teach you the two things that beginners find hardest — pressure control and stroke shape — anywhere, any time, with no setup.
This guide compares the brush pens I actually keep in my bag, explains which kind suits which purpose, and is honest about where the brush pen stops and the real brush begins.

Two kinds of brush pen, and why it matters
Before brands, one distinction that decides everything.
Felt-tip brush pens (the Tombow Fudenosuke, Kuretake Bimoji, Pentel Fude Touch) have a single flexible fibre point shaped like a brush. Press lightly for a thin line, press harder for a thick one. The tip springs back to a point on its own. They are forgiving, consistent and easy to control — and their strokes have a slightly uniform, “pen-like” edge that a trained eye can spot.
Bristle-tip brush pens (the Pentel Pocket Brush, Kuretake No. 22 and No. 13) have an actual bundle of synthetic hairs fed by an ink cartridge. They behave much more like a small real brush: the tip splits, drags, flicks and leaves the dry-brush texture (kasure, 掠れ) that makes calligraphy look alive. They are also harder to control, for exactly the same reason.
The rule I give students: felt tip to learn the shapes, bristle tip once the shapes are reliable. Most people should own one of each, and the two together still cost under $20.
What “best” means here
Four criteria, in order of importance.
- A tip that recovers. A brush pen tip should return to a clean point after a heavy stroke. Cheap pens go blunt within a page and then every stroke starts fat. All four pens below recover well; most of the ones I have thrown away did not.
- Pigment ink. Pigment ink dries water-resistant, sits matte on the paper and does not fade. Dye ink is brighter and cheaper but bleeds if it gets wet and looks glossy under light. For anything you might keep, pigment.
- Made by a Japanese pen maker. Tombow, Pentel, Kuretake and Akashiya have been making brush pens for decades and their quality control shows. The “12-pack of calligraphy brush pens” from a brand you have never heard of is, in my experience, twelve pens that skip criterion 1.
- A price that lets you use it up. A brush pen that costs $3 gets used every day. A brush pen that costs $30 gets saved for a special occasion that never arrives. With one exception below, everything here is under $10.
The honest shortlist
Four pens. Each is the best at one thing.
1. Tombow Fudenosuke (hard and soft tip) — the one to buy first
Tombow Fudenosuke Brush Pen, 2-pack (one hard, one soft) on Amazon · ~$6–9 for two
If you buy one thing from this page, buy this. The Fudenosuke (筆之助, roughly “brush’s helper”) is the most-used brush pen in the world for good reason: a small, firm felt tip in a slim body, with pigment ink, in two stiffnesses. The hard tip writes almost like a fine-liner until you lean on it; the soft tip flexes more and gives a wider range of stroke width.
What it does well: Control. A beginner can write a recognisable kanji with the hard tip in the first minute, which is not true of any bristle pen. The line is crisp and dark. The pen is cheap enough to keep three of them in different bags. Ink is water-resistant when dry.
What it doesn’t: The tip is small — good for characters up to about 3 cm tall, not for anything larger. The strokes, while clean, look like a pen doing an impression of a brush; there is no kasure, no split-tip texture. And the pens are disposable; a heavy user goes through one every few weeks.
Honest verdict: The right first brush pen for almost everyone. Start with the hard tip; move to the soft tip when your thin strokes stay thin without effort.
2. Pentel Pocket Brush (XFL2L) — the closest thing to a real brush
Pentel Fude Brush Pen, medium (XFL2L) on Amazon · ~$10–15, refills sold separately
This is the pen that illustrators and manga artists have used for decades, and it is the one I reach for when I want a brush pen to write like a brush. The tip is a bundle of fine synthetic bristles, fed by a replaceable pigment-ink cartridge. It splits, it drags, it flicks; a fast stroke leaves genuine dry-brush texture, and a slow one pools ink at the stop the way a real brush does.
What it does well: Expressiveness. Every technique you learn with a real brush — the pressed start, the lifted turn, the tapering sweep (harai, 払い) — is visible in the line. It refills, so one pen lasts years. Deep, matte, waterproof black.
What it doesn’t: Forgiveness. In an untrained hand the bristles go everywhere, and the first week is humbling in exactly the way the first week with a real brush is. It is also slightly too soft to write very small; anything under 1.5 cm gets muddy.
Honest verdict: The second brush pen to buy, once the Fudenosuke has taught your hand what a clean stroke feels like. If you are also learning with a real brush, this is the pen whose lessons carry over most directly.
3. Kuretake Bimoji set (extra fine to large) — for serious kanji practice
Kuretake Bimoji Brush Pen, 5-piece set on Amazon · ~$18–22 for five
Kuretake is one of the oldest calligraphy-supply names in Japan, and the Bimoji (美文字, “beautiful characters”) line was designed for one job: teaching Japanese adults to write better kanji. The set gives you the same felt-tip pen in a range of sizes from extra fine to large, plus one bristle-tip pen, so that you can practise a character at postcard size and again at a size closer to real brush practice.
What it does well: Range. The large tip writes a 5–6 cm character with real weight, which no Fudenosuke can do, and the extra-fine tip handles furigana-sized text. Consistent pigment ink across the set. The bodies are marked with the tip size in Japanese, which is the point: this is a Japanese-market product sold as-is, not a Western repackaging.
What it doesn’t: You pay for five pens and will use two of them most of the time. The felt tips are firmer than the Tombow soft tip and take slightly more pressure to open up. Disposable.
Honest verdict: The set for someone who has decided that kanji practice, specifically, is their goal. Pair the medium and large tips with our single-kanji series and a pad of practice paper, and you have a complete travelling practice kit.
4. Kuretake No. 13 Mannen Mouhitsu — the refillable “fountain brush”
Kuretake Mannen Mouhitsu No. 13, with spare cartridge on Amazon · ~$25–30
The exception to the under-$10 rule. Mannen mouhitsu (万年毛筆) means, more or less, “fountain hair-brush”: a bristle-tip pen built like a fountain pen, with a black lacquer-style body, a clip, and cartridge refills. Kuretake has made this design since the 1970s and it is the brush pen a Japanese adult buys when they want one good one for life.
What it does well: The bristles are longer and finer than the Pentel’s, closer to a small real brush, and the ink flow is generous — long strokes do not starve. It is the pen I use to sign finished pieces when a real kofude is not to hand. The body feels like an object worth keeping, which, for some people, is what makes them practise.
What it doesn’t: Costs three Pentels. Needs the cap on between strokes in dry climates or the tip dries. Same learning curve as any bristle pen.
Honest verdict: A gift-grade pen, and a fine one — for yourself once you know you will keep going, or for someone who already writes with a brush. Not a first pen.
What to skip
- Multi-colour brush-pen sets sold for “hand lettering.” Real products, and pleasant for lettering, but the tips are large, the inks are dye-based, and none of them are designed for kanji. Not wrong; just a different hobby.
- “Calligraphy brush pen sets” from unknown brands. Ten pens for $12 is ten tips that go blunt in a page.
- Water brush pens. These carry water, not ink, for watercolour. Useful for water-writing practice paper, useless as a brush pen.
- Any brush pen for practising grip. A brush pen is held like a pen. A real brush is held vertically, in a grip that has nothing to do with handwriting — see How to Hold a Japanese Calligraphy Brush. Do not let brush-pen practice teach your hand the wrong habit.
How to practise kanji with a brush pen
The method is the same as with a brush, scaled down.
- Paper first. Ordinary printer paper works but is slippery; a pad of slightly absorbent paper (a sketchbook, or hanshi cut into quarters) shows pressure changes far better.
- One character, many times. Choose a character with a full range of strokes — 永 (eternity), the character that contains all eight basic strokes, is the classic — and write it twenty times, watching one stroke at a time.
- Press, then lift. The single most useful brush-pen exercise: a horizontal stroke that starts with a press, thins in the middle, and ends with a press. When you can do this ten times in a row at the same width, you have learned what pressure control means, and it transfers to the brush directly.
- Stroke order, always. The pen will happily let you draw a character in any order. Follow the correct order anyway; it is the order that makes the shape. Every character in our kanji series shows it.
- Cap it. Felt tips dry out uncapped within minutes; bristle tips within an hour.
Where the brush pen stops
A brush pen will teach you stroke shape, pressure and rhythm. It will not teach you the three things that make shodō feel like shodō: loading ink (how much the brush carries, and how the stroke changes as it runs dry), the paper (how hanshi drinks ink and where it bleeds), and the vertical grip that connects the stroke to the whole arm rather than the fingers.
When the brush pen starts to feel easy — usually a month or two of daily use — that is the signal, not to buy a better brush pen, but to buy a brush. The best beginner’s calligraphy set costs about the same as the Kuretake No. 13 above and opens the door the brush pen was pointing at.
Where to go next
- The real thing — Best Japanese Calligraphy Brush for Beginners, when you are ready to trade the pen for hair and ink.
- How to hold a brush — the 7-step grip guide. Read it before your brush arrives, so the pen has not taught your hand the wrong thing.
- A character to start with — 心 (heart) is four strokes and unforgiving; 永 (eternity) is the full syllabus in one character.
- The daily routine — a Japanese calligraphy practice routine that fits in twenty minutes, which works just as well with a pen.
The brush pen is not a lesser brush. It is a different tool that happens to share a shape, and it is very good at the one thing beginners most need to learn before the brush makes any sense to them. Buy the Tombow, write one character a hundred times, and see whether you want more. Most people do.
Frequently Asked Questions
Is a brush pen the same as a calligraphy brush?
No. A brush pen (fude pen, 筆ペン) is a pen with a brush-shaped tip and its own ink supply. It teaches pressure control and stroke shape, which transfer to shodō, but it does not teach ink loading, paper feel, or the vertical grip a real brush requires. Treat it as a gateway and a travel tool, not a replacement.
Which brush pen is best for writing kanji?
For practising kanji shapes, a hard-tip felt brush pen such as the Tombow Fudenosuke hard tip or a Kuretake Bimoji fine/medium gives the most control. For strokes that look like real brushwork, a bristle-tip pen such as the Pentel Pocket Brush is closer to the real thing but harder to control.
Are Japanese brush pens waterproof?
It depends on the ink. Pigment-ink pens (Pentel Pocket Brush, Kuretake Bimoji, Tombow Fudenosuke) are water-resistant once dry and safe to add watercolor over. Dye-ink pens (Pentel Fude Touch Sign Pen, most colored brush pens) will bleed if they get wet.
Can you refill a brush pen?
Some. The Pentel Pocket Brush and the Kuretake No. 13 and No. 22 take replacement ink cartridges and last for years. Felt-tip pens such as the Tombow Fudenosuke and Kuretake Bimoji are disposable — cheap enough that this rarely matters.
