As I mentioned at the outset, this film is available in Germany as an extra on the DVD (Region 2) for The Wild Swans. This DVD has the German dub and the English dub but no subs. I have not found any other legit means of buying / viewing the film. Fans of the song “Nakanaiwa” can find it on Junko Sakura’s Golden Best album.
