Thank you for viewing. This is a Marumo Takagi Toki Onkan Sakura Momiji Hirahai (flat sake cup). This hirahai has a special coating that changes the color of the design depending on the temperature. When hot sake is poured into it, the black silhouette of the autumn leaves changes to cherry blossom pink. A hirahai is a shallow, wide-rimmed sake cup used for drinking Japanese sake. Ships the same day.
