The support for Japanese has been improved in LyX 1.6.x. Due to encoding
reasons, Japanese documents that were edited with LyX 1.6.x cannot correctly
be converted to the format of LyX 1.5.x and thus not edited with LyX 1.5.x.
+To be able to use LyX 1.6 with Japanese, the latest version of the LaTeX
+distribution "platex" must be installed.
+platex provides a Japanese variant of BibTeX named "jbibtex". When LyX is
+configured, this variant is used. In case you have problems with BibTeX-files
+that include Japanese or you need to use another BibTeX program, set it in LyX
+preferences under Output->LaTeX->BibTeX command.
