Erotic Journey: Love Affair in Hong Kong - Hirokazu Inoue (1973) - Kai Tak Airport

The final location we see is, fittingly, Kai Tak Airport, as Sumio's ever-suffering sister-in-law decides it is time to return to Japan and leave him to wallow in his sadness. Uncharacteristically, it looks like they have walked all the way there as they pop out of a subway on Olympic Avenue and walk towards the terminal. The subway is still there, the airport is not.
