Rain chain is a type of rain spout born in Japan to enjoy when it rains. Many tourists visiting Japan were intrigued by it, and it gradually gained recognition across the world due to those bringing it back with them to their home countries. However, it appears to be called by various names. In places where English is spoken, the most common name is “Rain Chain” or “Rain Chains”.
In my country, Japan, it is called “Kusari doi”, “Kusari toi”, “Toi Kusari” or “Kesho Kusari”. Because the country of origin is Japan, English speaking countries also use the same pronunciation and say “Kusari doi” or “Kusari toi”. Rain chains are for enjoying rain as a drain spout and I am certain that it will be embraced across the world by various names in the future.
