Hi. migemo is a Japanese incremental search tool for Emacs. You can search Japanese words on Emacs without Kanji conversion. I suggest app-emacs/migemo.

Hum, this seems cjk bug rather than elisp one (it needs Japanese knowledge to test, at least), so I'll take it.
I couldn't find 50migemo-gentoo.el used as a SITEFILE in the ebuild either here and GentooJP BugTrack. Will you create a new attachment here, Matsuu-san?
