One thing I notice is that aside from the mess of wires overhead, this all looks so mathematical, like the whole thing is planned to within the millimeter for maximum efficiency with all those straight lines and sharp edges...so at odds with the typical, iconic traditional building style with it's lovely curved roofs I find.
It does seem that way when it comes to Japanese architecture, like its all worked out for a reason, getting as much into such little space. Always amazes me!
