This mug was purchased at the Apple Store on the Infinite Loop campus. Apple Store employees indicate that each mug is slightly different, and they are made with a specific firing process by artisans in the historic town of Hasami in Nagasaki Prefecture, Japan.
The squarish handle is an element stylistic of other Hasami porcelain mugs. According to the website: “Hasami began crafting its porcelainware almost 400 years ago during the Edo period, distributing them throughout Japan as well as to Europe through the port of Nagasaki.”
In addition, “HASAMI PORCELAIN was designed by Takuhiro Shinomoto of Tortoise in Venice, CA whose vision was to integrate modern tableware design with the organic quality produced by traditional Japanese manufacturing techniques.”
