Japanese keyboard: Fedora 15 KDE

[jonetsu]

Hello all,
  
  I've seen a few softwares around to have some kind of keyboard able
to either input romanji based (hiragana based ?) characters or to draw
kanji, but these software seems to be age-old and not maintained
anymore, like anthy.  What is the preferred way to be able to use
Japanese characters in Fedora 15 with KDE ?

Thanks.
