probably one of the Buddhist manifestations of Kannon/Guanyin (from the hindu Avalokitesvara) the bodhisattva ("goddess" or Kami) of compassion and mercy Kannon has many female forms including the "thousand armed Kannon" (most famously represented in Sanjusangendo temple Kyoto).
Awesome picture. Something I can carry around with me for good luck, just like how some Buddhists keep a talisman of the deity's image in their wallets for good luck. I just gotta keep in mind not to place this image in particular together with my dollar notes. ^_^;;
