The Japanese line-break test
Japanese has no spaces between words, so a browser will break a line anywhere it likes — including the places the language forbids. Nobody reports this. A Japanese reader will not write to say your line started with a full stop; they will only feel that the page was not finished, and leave. This page measures it on your own screen, in your own browser, in real time. Paste anything.
The number is the count of visual lines that begin with a character Japanese typesetting does not allow at the head of a line. It is measured from the rendered line boxes in your browser — not asserted by us. Drag the column width and watch it move.
Three rules, none of which appear on anybody's checklist
- KinsokuA line may not begin with 。、)」』〕】!?ー々, and may not end with (「『〔【. The left pane lets the browser break anywhere, which is what a template does when it is told to prevent overflow. The right pane keeps the forbidden pairs together.
- AkiA quarter of an em belongs between a Japanese character and a Latin one — between 日本語 and Framer. Without it the two scripts touch, and the sentence reads as if it were pasted rather than set.
- PaltJapanese punctuation is drawn inside a full square, so a comma followed by a bracket opens a hole the width of a character. Proportional spacing closes it. The right pane has it on; the left does not.
There is a fourth, furigana — the small reading printed above a name — which has no equivalent anywhere in Framer or in plain CSS, and which every Japanese brand needs the moment a founder's name appears.
We wrote the three Framer plugins that fix it, and they are published
Kumihan does the line breaking. Rubi does the readings above a word. Waei does the air between Japanese and Latin. They are on the Framer marketplace, they are free, and they install in one click — so you can check the work on your own page before you speak to anyone here.
If you would rather not do it yourself: we design and build the whole site, in Framer, handed over on your own account. One page from $900, a full site from $3,000, a WordPress migration from $3,000.
Send us a page that has Japanese on it. We will tell you what it is doing wrong, for nothing.
