03 Furosakimado
A furosakimado (lit. “window beyond the brazier”) is a type of window made in the wall behind the brazier used in tea ceremonies, and it is named based on its location. It provides task lighting and ventilation for the area around the tea preparerʼs seat. The opening is typically designed as a shitajimado (exposed lath window) measuring about 55 centimeters in height and 42 to 45 centimeters in width, and it is equipped with a sill set about 23 centimeters from the surface of the floor, a frame with rounded inner corners, and a hanging shelf that partially overlaps the wall and is held together by a bamboo post. The threshold and lintel have a groove for a sliding paper screen, which is pulled towards the kitchen end and opens only about half way.


About the Yosuitei
Japanese teahouses (chashitsu) are unique buildings with small interiors and many types of windows. The Yosuitei is a thatched hut-style teahouse from the Kanei era (1624–1644) of the early Edo period. It was commissioned by Toshitsune Maeda, the second lord of the Kaga Domain, and built alongside a waiting shelter and a reception hall with a dais at the residence of Kakujo Goto, a sword engraver and Maeda clan liege based in Kyo (present-day Kyoto). Designed by Enshu Kobori, the multiwindowed teahouse is also referred to as the Jusansoseki (lit. “Thirteen-Window Tearoom”) based on the fact that it has thirteen windows, which is the most of any extant teahouse. This project aims to extract the subtle, rich behaviors of the Yosuiteiʼs thirteen windows by studying the sounds and movements that they make when opened and closed.



Index of Window Sounds and Movements
The Index of Window Sounds and Movements is a project to observe and extract the sounds and movements of operable windows in order to understand how we perceive windows with our ears and eyes. This is the first research project of Window Products Inside, and it is being conducted as a collaboration between product designer Yoh Komiyama and the Window Research Institute, with videography by Tomohiro Okazaki.


Window Products Inside
Windows Products Inside is a research project initiated by product designer Yoh Komiyama. By extracting and redefining the various meanings that are implicit to the window as an object, the project hopes to uncover what is needed so that windows can create a diversity of new lifestyles, cultures, and new customs.
