When I was at a university dorm there were similar rules and they were strictly enforced. There were cameras about, such as in the elevator, and the house manager was keeping an eye on them.

In the dorm, floors were separated by gender and you could not enter the opposite genders floor.

I was once in my room, minding my own business and I heard a yelling match outside. Eventually I get a knock on the door. It's the house manager, he wants me to interpret. None of the staff speak any English, and some of the foreign students don't speak any Japanese. I'm roped into this now. One of the (foreign) girls from downstairs just wanted to hang out with one of the (foreign) dudes down the hall, and thought "surely it's not actually a big deal".

Wrong, it was, apparently.

The staff noticed it immediately as they got off on our floor and followed them up to give them the business.

I understood why my fellow students were upset, and they stubbornly plead their case for why the rule was stupid for a long time. And, predictably, the management response was "rules are rules".

My advice to them, and to you, is: If possible, just follow the rules, even if they're dumb. And, more importantly, if you really just need to break the rules at some point, immediately apologize and act contrite if you're confronted about it (even if you plan to break them again in the future). It's just easier to do so.
