Treasure bag
宝袋 takarabukuro

The bag of treasures carried by the god Daikoku; a takaramono that promises inexhaustible wealth.
Iconography of the god Daikokuten; medieval to Edo period
Daikokuten began as the Indian god Mahākāla, came to Japan with Tendai Buddhism (credited to Saichō), and in the medieval period merged with the Shinto god Ōkuninushi, whose name can also be read Daikoku. His sack recalls Ōkuninushi carrying his brothers' bags in the Hare of Inaba story. From the 14th century he became a smiling figure with mallet, bag and rice bales, and in the Edo period one of the Seven Lucky Gods.
The treasure bag appears in takarazukushi sets and on New Year goods.
