问题
I'm writting a simple paragraph in both English and Japanese, using only HTML and CSS. The English text breaks lines normally (when a word doesn't fit on a line anymore, it's pushed to the next one).
With Japanese though, not a whole word is pushed to the next line, but part of it only. I've tried setting word-wrap to break-word and normal, but nothing changes (with the Japanese text).
How to I make whole words in Japanese jump to the next line like it happens in English?
回答1:
English separates words with spaces, Japanese doesn't.
Whether characters in Japanese form a word or not depends on context. In many cases, looking for certain grammatical (Kana) particles could be used to separate words - but this wouldn't even be close to being reliable.
Essentially, you'd need a Japanese dictionary / understanding of the language to identify where the words start and end - a browser won't know how to do this.
Alternatively, if you know the start and end of the words, you could perhaps wrap each one in a span - then use CSS to ensure each span wraps to a new line as a whole when it doesn't fit.

Japanese has specific rules that are followed when breaking text. They are called 禁則処理 (kinsoku shori). Here is a link explaining the rules. The rules are mostly concerned with special characters. Have a look at any popular Japanese webpage and you will see that multi-character (kana and kanji) words are often split. I often see です split between lines.
Update: I stumbled across this tool recently. I haven't tried it out yet, but the theory is solid. If someone is looking to improve the line breaks with Japanese text this could be a good solution.

try setting the css property
line-break:strict;

I'm not an expert with Japanese specifically so it's hard for me to tell if things are wrapping correctly, but I just had to solve this problem myself and both word-break: keep-all and white-space: nowrap seemed to solve the issue for me, so those might be worth trying out.
