Straw Millionaire
The legend of the Straw Millionaire (わらしべ長者, Warashibe Chōja), also known as Daietsu or the Daikokumai, is a Japanese Buddhist folk tale about a poor man who becomes wealthy through a series of successive trades, starting with a single piece of straw. It was likely written during the Heian period and was later collected into Konjaku Monogatarishū and Uji Shūi Monogatari.
