The Man in the High Castle - S03 subtitles for foreign language parts, where?

I finally got around watching “The Man in the High Castle” and for Season 01 and 02, sources I got had hardcoded subtitles in the video file for the Japanese and German spoken parts.

Now I have started Season 03 and those hardcoded subtitles are missing. No problem I thought, I just get some fanmade subtitles from the usual sites. Turns out it is a problem, none of the sites I checked have any subtitles that cover Japenese or German parts.

Anyone has a hint where I can find those? Even just Japanese would help, I can understand German, even though many actors there speak quite terribly.
