Houses commonly use downspouts to transport rainwater towards a drain. If you are not particular with downspout, it is a vertical pipe also known as downpipe connected to the roof gutter.
Rain chains also function the same way a downspout does. It is practically an alternative to a downspout but also more decorative in purpose. A rain chain is typically a chained series of metal cups with holes in the bottom to allow rainwater to drop usually towards a water storage. This is common and widely used in Japan.
Nowadays copper rain chains are commercially produced and sold. It varies in designs and more ornate for decorative purposes.
