Die Sieben Masken des Judoka - Heinz Drache (1967) - Hilton Hotel, Central

This location has popped up a few times now and it took a while before I worked out it was an inner courtyard at the Hilton Hotel. No one seems to have been able to confirm or deny it so far, but the fact that it keeps popping up confirms it was a real location and not any kind of studio set. We've already seen it previously in The Million Eyes of Sumuru but it was The Yin and Yang of Mr Go that helped actually place it properly.
