Kyūsu
A kyūsu is a traditional Japanese teapot mainly used for brewing green tea.
The common misconception is that a kyūsu always has a side handle. However, the word "kyūsu" merely means "teapot", even though in common usage kyūsu usually does refer to a teapot with a side handle.
The two most common types of kyūsu are yokode kyūsu, which has a side handle and which is the more common type, and ushirode kyūsu, which has a rear handle, just like teapots in other parts of the world; there are also uwade kyūsu.
Tokoname ware is known for its kyūsu. In smaller types, some of the lids can be crafted in such a way that they will not fall off due to water adhesion. The spout also has to be crafted with an angle that no drops will leak back from it while pouring.
