Stroke Order (筆順) Basics | Japanese Grammar

Every kanji is written as a fixed sequence of strokes in a fixed order. The order is not decorative tradition — it is what produces a balanced, legible character, and it is what handwriting-recognition software on your phone silently assumes you are following. The good news for a learner: stroke order (筆順（ひつじゅん）, hitsujun, also called 書き順（かきじゅん）kakijun) is almost entirely predictable from about six rules. Learn the rules once and you will know the order of characters you have never written before.

Why order matters even if you never handwrite

It is tempting for an English speaker to treat a kanji as a little picture and draw the lines in whatever order looks convenient. Resist this. Correct stroke order pays off in four concrete ways.

Legibility and proportion. The rules exist because writing in that order naturally lands each stroke in the right place and the right size. Characters written out of order come out cramped, lopsided, or ambiguous.
Handwriting and OCR input. When you draw a kanji on a phone keyboard or in a dictionary app, the recognizer matches your stroke sequence, not just the final shape. Draw 木 bottom-up and it may guess the wrong character.
Reading cursive. Semi-cursive (行書（ぎょうしょ）, gyōsho) and cursive (草書（そうしょ）, sōsho) hands connect and abbreviate strokes. Those connections only make sense — and are only readable — if you know the standard order underneath.
Counting strokes. Reliable stroke order is what lets you count strokes reliably, which still matters for dictionary lookup. See Counting Strokes and Dictionary Lookup.

💡

Stroke order is a small, one-time memorization cost with an outsized payoff. Unlike vocabulary, it does not keep growing — the same six rules cover thousands of characters.

The core rules

Rule 1 — Top to bottom

Horizontal strokes and stacked components are written from the top down. The clearest illustration is the number three, 三（さん）, san: top bar, then middle bar, then bottom bar.

Kanji	Reading	Strokes	Order
一	いち (ichi)	1	One horizontal, drawn left → right
二	に (ni)	2	Top bar, then bottom bar (top → bottom)
三	さん (san)	3	Top bar, middle bar, bottom bar

一から始めましょう。

ichi kara hajimemashō

Let's start from scratch (from one).

二、三日で終わります。

ni, san-nichi de owarimasu

It'll be finished in two or three days.

Rule 2 — Left to right

When strokes or components sit side by side, work from left to right. The three verticals of 川（かわ）, kawa, "river," go leftmost first, then middle, then right.

この川はとても浅いです。

kono kawa wa totemo asai desu

This river is very shallow.

Rule 3 — Horizontal before vertical when they cross

Where a horizontal and a vertical stroke intersect, the horizontal comes first. The number ten, 十（じゅう）, jū, is the textbook case: draw the horizontal bar left → right, then the vertical top → bottom.

Kanji	Reading	Strokes	Order
十	じゅう (jū)	2	Horizontal (left → right), then vertical (top → bottom)
木	き (ki)	4	Horizontal, then vertical through it, then left diagonal, then right diagonal

Notice 木（き）, ki, "tree," stacks several rules at once: horizontal-before-vertical for the cross at the top, then the two diagonals resolved by Rule 5 below.

十時に駅で会いましょう。

jūji ni eki de aimashō

Let's meet at the station at ten o'clock.

庭に大きな木があります。

niwa ni ōkina ki ga arimasu

There's a big tree in the garden.

Rule 4 — Outside before inside, then close the box

For enclosed characters, draw the enclosing frame first, then whatever is inside, and seal the bottom of the box last. In 国（くに）, kuni, "country," you write the left vertical and the top-and-right corner, then the 玉 inside, and only then the bottom stroke that closes the frame. Same logic for 回（かい）, kai: outer box (minus the base), inner 口, then the closing stroke.

どこの国から来ましたか。

doko no kuni kara kimashita ka

What country are you from?

もう一回言ってください。

mō ikkai itte kudasai

Please say it one more time.

💡

The "close the box last" half of Rule 4 is the one beginners forget. If you seal the bottom before writing the inside, you literally trap your brush outside the character. Frame → contents → floor, in that order.

Rule 5 — Left diagonal before right diagonal

When a left-falling stroke (ノ) and a right-falling stroke (乀) meet, the left one comes first. The person character, 人（ひと）, hito, is two strokes: the left-falling diagonal, then the right-falling one that leans on it.

Kanji	Reading	Strokes	Order
人	ひと (hito)	2	Left-falling diagonal (ノ), then right-falling diagonal

あの人は誰ですか。

ano hito wa dare desu ka

Who is that person?

八人で旅行しました。

hachi-nin de ryokō shimashita

Eight of us went on a trip together.

Rule 6 — Two useful tie-breakers

Two more patterns resolve most of what the first five rules leave open:

A vertical that pierces the whole character is written last. In 中（なか）, naka, "middle," you draw the box first and run the central vertical through it at the end.
A long horizontal that underlines the character can come last (for example the base stroke of 女（おんな）, onna). And center before wings: in 小（ちいさい）, chiisai, the central hook comes first, then the left and right dots.

箱の中に何が入っていますか。

hako no naka ni nani ga haitte imasu ka

What's inside the box?

Putting it together: 木 stroke by stroke

Because 木 combines three rules, it is worth walking through slowly:

Horizontal bar, left → right (Rule 1 direction, Rule 3 says it precedes the vertical).
Vertical running down through the bar, top → bottom (Rule 3).
Left-falling diagonal branching from the crossing point (Rule 5, left first).
Right-falling diagonal on the other side (Rule 5, right second).

Do it in that order a few times and your 木 will come out symmetrical automatically. Do it out of order and the crossbar drifts and the branches fight for space — which is exactly the difference a native reader notices at a glance.

How this connects to radicals

Because components are written as self-contained blocks (finish one before starting the next), stroke order and the radical (部首) system reinforce each other. The water radical さんずい on the left of 海 or 川-adjacent characters is always its own three-stroke unit, written top to bottom before you move to the right side of the character. Recognizing radicals tells you where one block ends and the next begins, which in turn tells you the order.

Common mistakes

❌ 十を縦から先に書く

jū o tate kara saki ni kaku

Incorrect — Rule 3 says the horizontal is written before the crossing vertical.

✅ 十を横から先に書く

jū o yoko kara saki ni kaku

Correct: horizontal-before-vertical when they cross.

❌ 国の一番下の線を、中を書く前に閉じる

ichiban shita no sen o naka o kaku mae ni tojiru

Incorrect — closing the bottom of the box before writing the inside.

✅ 国 = 枠 → 中の玉 → 下の線でふたをする

waku → naka no tama → shita no sen de futa o suru

Correct: frame, then contents, then seal the bottom last.

❌ 人 = 右のはらいを先に書く

migi no harai o saki ni kaku

Incorrect — writing the right-falling stroke first.

✅ 人 = 左のはらいを先に書く

hidari no harai o saki ni kaku

Correct: the left-falling diagonal comes before the right-falling one.

❌ 三を下から上へ書く

san o shita kara ue e kaku

Incorrect — writing the three bars bottom-to-top.

✅ 三を上から下へ書く

san o ue kara shita e kaku

Correct: top bar, middle bar, bottom bar, top to bottom.

The underlying error behind all four is the same one English speakers make most: treating a kanji as a picture to be filled in from any direction, rather than a sequence to be performed. Learn the sequence and legibility, proportion, stroke counting, and handwriting input all come for free.

Key takeaways

Six rules — top→bottom, left→right, horizontal-before-crossing-vertical, outside-then-inside-then-close, left-diagonal-before-right, and the piercing-vertical-last tie-breaker — cover the overwhelming majority of characters.
Order is not optional flourish: it drives proportion, feeds handwriting/OCR recognition, underlies cursive, and lets you count strokes.
Memorize the model characters 一・二・三・十・人・木; almost everything else is these patterns recombined.
