--- Comment #5 from Rafał Mużyło galtgendo@o2.pl --- The only (relevant here) font replacements I have set up are for MS default fontsets (3 Gothic and 2 Mincho) including their Japanese names (I'm not sure if that part is still necessary as over the years there have been a few commits that might have addressed it, but I see no harm in keeping those).
Bug 42606 has a workaround patch and could be tested for by creating a *clean* prefix in the Japanese locale (WINEPREFIX=<whatever>) - that way the cached values will be the Japanese ones.
