kana kanji font フォント

I am searching diligently for a Japanese Unicode web font ( フォント ) with fine ( light or extra-light ) kana (hiragana, katakana and furigana) but strongly stroked kanji so that in a phrase with only few kanji, the effect will be one of the kanji characters standing out.

The alternative is to use extensive markup or to script based on the binary value of the characters.

What approach will I take for web languages which have string types or values, but no char type?
