This is a teacup made by Kato Shundai, who was banished from Nagoya Castle during the Edo period, when he opened a kiln in the Imao area of Gifu. It appears to be covered with Oribe glaze, but it is not Oribe glaze, as it was impossible to use Oribe glaze during the Edo period. Later, he returned to his hometown of Seto City and made pottery in the Akazu area. Please check the images before purchasing. Thank you.
