"Her temples and shrines are almost invariably in the neighborhood of water -- the sea, a river, or a pond. She is the patroness of music, the fine arts (dancing, acting, visual), and good fortune in general, and is often shown carrying a biwa (Japanese mandolin) or playing a lute. She is often represented as a beautiful woman with the power to assume the form of a serpent, or shown seated on a dragon or serpent and playing a lute. In fact, the snake is almost always associated with Benzaiten, who was originally a Hindu deity (Sarasvati) who represented learning, music and poetry. Such artistic learning and wisdom often bring prosperity, hence her inclusion in the Japanese group of seven luckies. She also has a jewel that grants desires. Some say it is a jade, while others say it is a pearl."
I think the Bento boxes fit perfectly with Benten - Bento is Japanese lunch box, usually seafood and often made for children, and the name reminds also of the Goddess :-)
