Wow, Urashiman is old even by my standards, dating to 1983. The first half somehow showed up at Hulu, and I found that it had a few DID scenes:
Episode #12, around 20:15 - handgagging (also reported in the handgag folder).
Episode #22, 14:30 - young woman in inverted suspension. Rope is tied to her feet, but her arms are behind her so we don't see the bindings there.
Episode #25, 16:00 - another young woman with her arms held behind her. Starting around 18:00, she's tied with rope to a thin post.
