Thank you for viewing. This is a blue teacup from the Mijo Kiln (御代窯) of Izumo ware. It's difficult to tell from the photos, but it has a very mystical blue glaze. It's a brighter, more aqua color than in the photos. It appears to have been used very little, but has been stored for a long time. The teacup itself is in beautiful condition, but the box shows its age. Please understand this before purchasing. Height: Approximately 6.8 cm Diameter: Approximately 14 cm
