This is a railway commemorative teacup purchased in December from an antique shop, marked "Kutani Toko." It appears to be a tea bowl, and a poem is written on the side (in cursive script, undecipherable). Recommended for railway enthusiasts, those who enjoy poetry and want to decipher it, and tea bowl lovers. Please refer to the photos for the size. The weight is 122.7g. There are no tea stains, and it appears to have been displayed rather than used. It is likely Kutani ware. Item... Tea bowl/Rice bowl
