This style of teapot is sometimes called a "shiboridashi", and it is generally reserved for brewing high-quality, whole-leaf Japanese green teas (such as gyokuro, kabuse, and light-steamed teas). The proportions create an ideal space for the needle-like leaves to fully unfurl over the course of several steeps, and encourage a higher leaf-to-water ratio.
This piece was made by Hokujo, an artist from the city of Tokoname in Aichi Prefecture who is renowned for the style and quality of his work.
Over time, the porous, unglazed clay will become seasoned with the aroma of the tea, so we suggest reserving it solely for Japanese, non-roasted green teas.
Because each piece is hand-made, please note that some characteristic may differ slightly from the pictures provided.
