These Japanese copper cups have been manufactured in Takaoka, Toyama Prefecture, an area that has been popular for its metal cast products since 1611. The company began making iron cast farming tools and gradually advanced to producing bronze cast bells and statues for buddhist temples. The company crafts their products under their “Monozukuri” to deliver the best of copper products to modern customers. Any proper bar would serve their Moscow Mules in a copper cup. The copper’s high thermal conductivity allows the beverage's chilled temperature for a longer period. The red and white color scheme of these cups represents good luck in Japan, which makes these a versatile gift for any social occasion.
