Rain chain

Rain chain with copper Cups

Rain chains (Japanese: 鎖樋, kusari-toi or kusari-doi,^[1] literally "chain-gutter") are alternatives to a downspout. They are widely used in Japan. Their purpose is largely decorative, to make a water feature out of the transport of rainwater from the guttering downwards to a drain or to a storage container. (Rainwater is sometimes collected for household usage.) They can also be found on temples.^[2]

Rain chains are typically either a series of metal cups, chained together with a hole in the bottom of each, or chain links that span vertically.^[2] Rain water run-off gets distributed from a rooftop gutter downward through the rain chain.

Rain chains have also been used in the West. Nordic vernacular architecture often used a simple stick as a rainwater guide, in similar fashion. They have also been used in the Modernist era, to juxtapose metal chains with a concrete or Portland stone facade.
