Thank you for viewing. This teacup was purchased at an antique market about 10 years ago. I was told by the shop owner that it is a Chinese antique. The movements of all the cranes are different, and since there is only one seam in the stamp, it is believed to be pressed with a single stamp. The lines are also fine and detailed. It is a small size, about the size of a sake cup or a "guinomi" (small sake cup). We used it not only for tea, but also with Japanese sake at home. The wide mouth allows for a good aroma, and the rim is outward, making the taste even more refreshing. It's interesting how the taste changes with the vessel. There is a crack of about 5mm on one edge, and another part where the glaze is thin. This is probably a kiln scar. Please check the other details in the images.
