I just uploaded a long (45 minute) look at Expo 85 to YouTube.
I hope you'll enjoy this look at what was a fun fair, even if you didn't speak Japanese. Thanks to the tape I now understand some of the shows that had me confused back in 1985.
Thanks to Rick Rann for sending me the VHS tape. I have a few others as well, so if enough people enjoy this one I'll add them.
