A Java library to transliterate Kanji-Kana-mixed Japanese text into Hiragana, Katakana, or Romaji representations. The Kanada is also useful for text segmentation processing (word-splitting or 'wakachi-gaki') for further morphological analysis.
This is something I wrote (ported from KAKASI) in the early 2000s and hasn't been maintained since then. I'm planning to refine the library so that it become useful for Android app developers.
