The Japanese Fairy Book

Long, long ago there lived, in Japan a brave warrior known to all as Tawara Toda, or "My Lord Bag of Rice." His true name was Fujiwara Hidesato, and there is a very interesting story of how he came to change his name. One day he sallied forth in search of adventures, for he had the nature of a warrior and could not bear to be idle. So he buckled on his two swords, took his huge bow, much taller than himself, in his hand, and slinging his quiver on his back started out. He had not gone far when he came to the bridge of Seta-no-Karashi spanning one end of the beautiful Lake Biwa. No sooner had he set foot on the bridge than he saw lying right across his path a huge serpent-dragon.
