seo inc. and jun hashimoto clad JCCU façade with toh rain-chain

rain-chain (kusari-toi in japanese) is a general term used to describe any object which hangs from a residential roof and functions as an eave spout. a japanese style, the functional pieces first started showing up around the azuchi momoyama period approximately 1558-1600AD. at that time, fibers from the outermost layer of hemp plants were woven into a rope, which was then hung on a home’s eaves.

 

UPDATE: the co op kyosai plaza won the ‘office – completed buildings award’ at the 2017 world architecture festival.

a lot has occurred since then, but the rain-chain is still in use, finding its home now as exterior decoration on the co-op kyosai building belonging to the japanese consumers’ cooperative union. created in collaboration between seo inc. and interior designer jun hashimoto, ‘toh’ — rain-chain model — has been installed on the entirety of the front and back of the multi-story façade. the building was designed by tatsuya hatori and nikken sekkei ltd.

  • Would have been nice to see a video of these ‘in action’. So.. are the sections of tubing the active parts ..or simply a variant?
