The following diff seems to choose the right font:

--- a/src/java.desktop/windows/data/fontconfig/fontconfig.properties
+++ b/src/java.desktop/windows/data/fontconfig/fontconfig.properties

+sequence.allfonts.UTF-8.ja=japanese,alphabetic,dingbats,symbol

 sequence.allfonts.windows-1255=hebrew,alphabetic/1252,dingbats,symbol

This diff intends to choose the `japanese` set before the `alphabetic` set, in case for `ja` locale in `UTF-8` file encoding. I am not saying this is the right fix, but could be a starting point.
