Much of the architecture in Japan is quite boring.  However, almost everyday I manage to find something out of the ordinary and a bit unusual for this city. The Hiro-o Complex has a glass facade with balconies and external stairs that add interest.  The most interesting part is that the glass facade has been put up over a very plain concrete building.  I think this idea should be used more often.  It would create more diversity and provide visual relief from the sameness pervading on every street.
