Windows and craftspeople act as partners in Japanese workplaces where work is conducted by hand. Windows take part in the manufacturing processes by bringing in or expelling elements of nature, such as light, wind, heat, smoke and steam. The properties of materials such as clay, wood, cloth and paper are transformed around such 'working windows,' and craftspeople hone their sensitivity and skills by acutely sensing these changes through their everyday work.Windows hence establish links between various things and their behaviors, and in doing so, they enable us to understand the ecologies that surround us.
