Yoh Komiyama (Product Designer)

Born in 1980 in Tokyo. Founding member of the Window Research Institute. After graduating from Tama Art University, working in an architectural design firm, and as a product designer for a manufacturer, he established Yoh Komiyama Design in 2011, based in Tokyo and Shanghai, a multidisciplinary firm that offers R&D support for both Japanese and foreign
corporations and organizations primarily in the field of product design, develops hardware and services, and handles brand direction. In recent years, the firm has been exploring new forms of craftsmanship and object-making by thinking about the object at hand through protocol and generative approaches and designing a set of rules pertaining to it. Some of his main projects in Japan include the Karimoku Cat series for the furniture company Karimoku, and product design for T Air, the first digital product from Tsutaya Books. His works have
been shown at “TC&D” at the Tokyo Metropolitan Art Museum. Outside Japan, Komiyama has shown his research project “mold” as part of Ventura Projects, at the Salone del Mobile in Milan, at Interni’s “Feeding: New Ideas for the City,” and at the multi-brand boutique Merci in Paris.

Vertical Outward Projecting Window

In this sort of window, either the left or right frame serves as the axis of rotation: it moves to the left or right along a groove or rail attached to the top and bottom of the window frame. The other frame allows the window to open by rotating onto the exterior. The rotation and the horizontal movement occurs simultaneously.

Power Window

Windows that open and close mainly through electric power using a switch or remote control to operate them are called power windows. As they can be opened and closed without touching them directly, they are used in situations where the window is question is rather heavy, or installed in locations where it is hard to reach. In recent years it has also become possible to operate such windows from a smartphone by linking them to internet technologies.

High Altitude Window

Installed in a high place such as the top of a stairwell, this sort of window facilitates “gravitational ventilation” by making use of how warm air rises. They are opened and closed using a switch or remote control, or using ball chains (operated manually). The ball chain mechanism is unique: the axis and chain that open and close the window are connected to each other, so that it opens when one pulls the chain from a distance.

Casement Window

Casement windows open by rotating horizontally to the left and right from the center, taking either the left or right edge as an axis. Some open into the interior, while others open onto the exterior. Both the left and right panels have the same dimensions: those that only open in one direction are called kannon-biraki (“goddess of mercy”), while those where one side is larger than the other are called oyako-biraki (“parent-and-child”). The ones opening in only one direction used in France since the 16th century are known as French windows.

Sash Window

A window that opens and closes by moving two or more parallel panels vertically over two or more grooves or rails is called a double sliding window, where both the top and bottom panels move. These sorts of windows developed primarily in the context of English stone built houses, and are commonly used even today in England as well as North America.

Double Sliding Window

A window that opens and closes by moving two or more parallel panels horizontally over two or more grooves or rails is called a double sliding window, where both the left and right panels move. This sort of window is an ancient Japanese mechanism for opening and closing, and its original form can be traced back to the yarido sliding panels of the Heian era (B.C. 794 to 1185). They are commonly used even today in Japanese homes.
