I did some research about how rooms look, what are the views etc.
I found quite a few reviews on Tripadvisor where people were staying in "normal" rooms far away from $5000 per night.
And they had only one window - with a fake balcony (AKA "safety bars"). And the window would not open more than a pinch. And people were really upset about it.
I understand (I think - as I am not a "Japanese type" person

) why they open the windows for people paying $5000 dollars per a night. Who is going to stay in this suite otherwise?
But I also understand that safety concern has nothing to do with it.
Though I also understand that the hotel doesn't really care if people are happy or not, as they say hotels there work at 95% capacity every single day.
