04/05 Shitajimado and Renjimado
Enshu liked to stack shitajimado (exposed lath window) on top of renjimado (slatted window), and he has done so in three places at the Yosuitei. This shitajimado has a single sliding paper screen, and the renjimado has double sliding paper panels (fusuma). These small, low-lying sliding panels are the most unique of the Yosuiteiʼs features. When closed, they shut out sunlight like solid walls, and when opened, they create bright and airy openings that transform the room of shadows into a room of light. The placement of the renjimado with its bottom edge touching the floor is an original design idea, and it was likely positioned so low to provide a glimpse of the large pond that the teahouse originally stood beside.


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.
