Rain chains are a beautiful and functional alternative to traditional, closed gutter downspouts. Rain chains (‘kusari doi’ in Japanese) in concept are not a new idea. For hundreds of years, the Japanese have used the roof of their homes to collect water, transporting it downward with chains and finally depositing the rain water into large barrels for household water usage. Japanese temples often incorporate quite ornate and large rain chains into their design. Rain chains have been spotted in South America, where chain is easier to obtain that machined downspouts.
