That is because your font just doesn't satisfy the requirements of
ja.orth. you can check what glyphs are really missing in the font.

I did write a small tool to do that some while ago.  I don't know if
it still works and need to rewrite it according to some advice but
anyway. see https://bugs.freedesktop.org/show_bug.cgi?id=29312
