Similarly, Japanese spaces tend to focus on structuring interactions, contingency, and connections to other people and to society. For example, traditional tea houses have doors that are narrow and low. This forces guests to lower their head and, historically, for samurai to leave their swords outside by the door. The doors serve to remind entrants of their relationship to the host (their lowered head) and to the broader culture (where weapons are not appropriate). In this way, they build spaces as extensions of culture and values, rather than as places where culture happens.
