In Japanese folklore the Takarabune is a treasure ship sailed through the skies by the Seven Lucky Gods during the first three days of the New Year. It is an essential part of Japanese New Year celebrations, the ship carries many treasures including the hat of invisibility, the bottomless purse, scrolls of wisdom and life, the keys to the secret treasure shed of the gods, the magic mallet, the lucky raincoat, the fairy feather robe and the bag of fortune. It is said to dock at Human ports spreading luck and joy and distributing gifts for the New Year.
It is customary to place a woodblock print of the Takarabune under your pillow on the 2nd January in the hopes that you will have a lucky dream. In the event of a nightmare the print must be thrown in a river. This tradition started in the Muromachi Period (1336-1573) and grew popular in the Edo period, it is still a tradition followed today. It is customary to present Children with a red envelope of money emblazoned with the Takarabune symbol.
