This is a Banko-yaki kyusu (teapot). It has a simple design, and the lid is large, making it easy to put in tea leaves. Compared to a kyusu by Seizan Sasaoka, it is made quite thinly. Unfortunately, there is a small chip on the spout (please check the third image), but it can be poured without any problems. It has gained character through many years of use. I think it would be to Hideo Hata's liking. I don't know much about the mark "Hakusan" due to my limited knowledge. It has been used for a long time and has gained character. There is no box. Since there is no Banko-yaki listed, I am listing it as Tokoname-yaki. Height: Approximately 6cm Width: Approximately 7.4 x 11.5cm Lid diameter: Approximately 6.3cm Please only purchase if you understand that this is a used item.
