I believe this is Arita-yaki, but I've disposed of the original box, so the details are unknown. Size: Diameter approximately 9 cm, Height 5.5 cm. There appears to be some staining from the glaze inside (photo 4). It has been stored at home, mostly unused. The teacups in the photo are separate, but I will include them. Please understand that this is a long-term home storage item and has been inspected by an amateur. Thank you.
