This is a red cup and saucer from Nikko's "Sansui" (Mountains and Water) series. The design is called the "Willow Pattern," and it was a popular design worldwide in the 19th century. The pattern features a pagoda, two birds, willow trees, a fence, three figures crossing a bridge, and a small boat. It is said that this design is based on a love story between the daughter of a wealthy Chinese man and a servant. There are no cracks or chips. Nothing is written on the bottom or inside, so there is a possibility that it is a different item or an imitation, but please understand that it is sold as-is.
