Examples of Rain Chains Used As Decorative Elements for Buildings
In Japan, the term "façade" is often used to describe decorative exterior elements of large buildings, such as office buildings. It is unclear to me whether the same term is commonly used for decorative exteriors in other countries; therefore, in this column, we define "façade" as exterior decorations for larger buildings.
A façade plays a crucial role in shaping the design and impression of a building. Commercial buildings, where aesthetics is a priority, almost always invest in façade design.
Unlike standard rain chain installations that use one or two chains, a façade consists of dozens or even hundreds of rain chains arranged together in various patterns to create a striking visual effect on the most prominent part of a building. While a single rain chain serves as a linear decorative element, grouping many together transforms them into a surface composition that functions as a façade.
Typically, rain chains are used to guide rainwater, but when incorporated into a façade, they may serve purely decorative purposes without water flow. In some cases, only a few rain chains allow water to flow, while the majority remain dry. Since rain chains can cause water to splash when handling large volumes of rainwater, careful consideration is necessary when determining the placement of functional rain chains in areas where splashing must be minimized.
Of course, it is also possible to channel water through all installed rain chains, turning them into a dynamic water monument. We look forward to seeing more examples of such installations in the future!
Rikkyo University, Niiza Campus
Location: Niiza City, Tokyo
Rain Chain Type: Hammon Silver
Total Number Used: 216 chains
This project features SEO Inc.'s rain chains, specifically the Hammon model in silver. A total of 216 rain chains are incorporated as a façade, complementing the building’s clean and minimalist exterior. Some of the rain chains allow water to flow, guiding rainwater from the outdoors down to the ground.
COOP Kyosai Plaza
Location: Shibuya, Tokyo
Rain Chain Type: Toh Silver, Customized wire spec
Total Number Used: 720 chains
Near the National Stadium, the main venue of the 2021 Tokyo Olympics, there is a building covered with rain chains. A total of 720 custom wire-style Toh rain chains are used, intertwined with climbing plants to form a façade. This rain chain and greenery façade also helps reduce energy consumption for cooling during the summer.
Asanuma Corporation, Nagoya Branch
Location: Shibuya, Tokyo
Rain Chain Type: Toh Copper Model, customized wire spec
Total Number Used: 50 chains
Copper rain chains have been incorporated into the façade of this renovated building, originally constructed 30 years ago. These rain chains not only guide water but also help nourish the greenery adorning the exterior.
When using rain chains on the upper floors of buildings, as seen in the photo examples, standard rain chains may not have sufficient strength. Instead, custom-designed rain chains reinforced with wire are used to enhance durability.
Installing rain chains at high elevations increases exposure to strong winds, which can lead to damage or even the risk of falling. For this reason, reinforced custom specifications are necessary.
