This is a small charming ceramic Japanese teacup decorated with four beautifully painted sakura (cherry blossom) flowers on its sides. 

The light pink sakura flowers are highlighted on a shiny surface created by a coat of a lustrous glaze. At Tasei Kiln, two skilled female artisans with over 40 years of experience paint intricate and graceful patterns, and coat each item with a luster glaze. Their special technique gives the teacup a luxurious and stylish feel. The sakura designs are masked, and then the remaining surface is given the luster glaze. The glazed surface has a distinct textured glossy glimmer and shines beautifully under light. 

Furthermore, what makes this teacup special is the appearance of a cherry blossom design when green tea is poured into the teacup. You can enjoy the delicate design of a cherry blossom on the outside and the inside of the teacup. 

To create a beautiful sakura theme setting for a tea party, match the cup with the teapot and small plate in the same sakura motif.
