This Japanese Mask has two names, Otafuku and Okame. Otafuku literally means “Much Good Fortune”, and Okame means “Tortoise”, also a lucky symbol for long life. Otafuku represents a smiling Japanese woman who brings happiness and good fortune to any man she marries. She is also known as the bringer of Mirth.

Okame, also known as Uzume or Otafuku is the name for the female half of a traditional Japanese Kyogen theatre pair. She is  frequently seen in Japanese art. Her full cheeks and her merry eyes are quite unforgettable.
