A kyusu is a traditional Japanese teapot made from clay. Its iconic characteristic is a single handle. Although in Japan people use the term "kyusu" to refer to all teapots, in the West we use it only for Japanese side-handled teapots.
A standard kyusu is slightly smaller than the average Western teapot. It can be anywhere from 3 - 12 oz. Although people use slightly larger ones for serving Japanese tea to guests.
A traditional kyusu has a handle at a 90-degree angle to the spout, though variations are not uncommon. Many believe that kyusu, compared to Western teapots of the same size, are much easier to handle and are more gentle on the wrists of the person serving tea.
Maintenance:
Rinse with hot water after each use
Run water through the spout to clean built-in spout, if applicable.
Remove lid and allow the teapot to air dry completely before storing.
