Interesting, if short, work on the differece between Western/Chinese and Japanese architecture. Ashihara grounds part of his thesis weather, which is reasonable enough, but also bases a portion of it on the Japanese practice of removing shoes within the house, arguing that this creates a "floor-based" architectural style as opposed to a "wall-based" one in Western culture: i.e., walls take more prominence in Western culture because furniture and hangings are removed from the floor, due to it being perceived as less clean than Japanese ones.
Compellingly argued.
