Kyusu -teapot-

Japanese tea pot is called kyusu. “Kyu” literally means "surprise" and  "su" does "use". So it refers to a thing which is used on a surprise occasion.

In old days, kyusu would be used to warm sake in China, coming to be for tea as it is now.

In the past, having a surprise guest, people must have served tea (could be sake earlier) made with kyusu. Nowadays, less people use kyusu unfortunately. When a surprise guest is paid a visit, tea might be served from a bottle. :-(
