Color-Changing Sakura Sake Cup – Copper

Pour cold sake and watch cherry blossoms bloom. The Color-Changing Sakura Sake Cup is one of those rare objects that is as magical to use as it is beautiful to behold. Made in Japan from copper and coated with heat-sensitive pigments, it reveals a vivid sakura pattern the moment the temperature drops below 16°C (61°F).

Made from copper for exceptional thermal conductivity, the cup chills instantly when cold sake or ice is added, keeping your drink colder for longer. A tin-plated interior lining minimizes any metallic taste, letting the character of the sake come through cleanly. The gently curved drinking spout is shaped to follow the natural contour of the lips, making every sip feel considered.

A gift-worthy piece for the sake enthusiast, the cocktail lover, or anyone who appreciates the intersection of Japanese craft and quiet wonder.

Care & Storage

• Hand wash only with mild dish soap — do not use abrasive cleaners or scouring pads.
• Wipe away any moisture thoroughly before storing, as water left on the surface may cause staining or darkening.
• Avoid dishwasher use, as heat and detergent may damage the heat-sensitive coating.
• Store away from direct sunlight or strong light to preserve the color-changing illustration.
• This cup is designed for cold beverages only — copper conducts heat efficiently, and hot drinks may cause burns.
• Colors may appear differently depending on monitor settings, lighting, and photographic conditions.
