In one of the tea-houses a thriving trade is carried on in the sale of wooden tablets, some six inches square, adorned with the picture of a pink cuttlefish on a bright blue ground. These are ex-votos, destined to be offered up at the Temple of Yakushi Niurai, the Buddhist Æsculapius, which stands opposite, and concerning the foundation of which the following legend is told. In the days of old there was a priest called Jikaku, who at the age of forty years, it being the autumn of the tenth year of the period called Tenchô (A.D. 833), was suffering from disease of the eyes, which had attacked him three years before. In order to be healed from this disease he carved a figure of Yakushi Niurai, to which he used to offer up his prayers. Five years later he went to China, taking with him the figure as his guardian saint, and at a place called Kairetsu it protected him from robbers and wild beasts and from other calamities. There he passed his time in studying the sacred laws both hidden and revealed, and after nine years set sail to return to Japan. When he was on the high seas a storm arose, and a great fish attacked and tried to swamp the ship, so that the rudder and mast were broken, and the nearest shore being that of a land inhabited by devils, to retreat or to advance was equally dangerous. Then the holy man prayed to the patron saint whose image he carried, and as he prayed, behold the true Yakushi Niurai appeared in the centre of the ship, and said to him-- "Verily, thou hast travelled far that the sacred laws might be revealed for the salvation of many men; now, therefore, take my image, which thou carriest in thy bosom, and cast it into the sea, that the wind may abate, and that thou mayest be delivered from this land of devils."
