Can you give a more detailed description? Was just a run-of-the-mill Japanese capsule hotel (https://en.wikipedia.org/wiki/Capsule_hotel)? Those were already common in 1991 (https://www.flickr.com/photos/glenhsparky/4820691940), and would have been certainly exotically sci-fi to an early-90s American audience.
> Just the trailer - it's a 5 hour film and hard to find the specific scene on youtube
Wow. some time ago that film connected with me for some reason (why, I have no recollection), so I have a VHS copy (because it was unavailable in any other format). That cut is much shorter.
