Hard by Asakusa is the theatre street. The theatres are called _Shiba-i_,[35] "turf places," from the fact that the first theatrical performances were held on a turf plot. The origin of the drama in Japan, as elsewhere, was religious. In the reign of the Emperor Heijô (A.D. 805), there was a sudden volcanic depression of the earth close by a pond called Sarusawa, or the Monkey's Marsh, at Nara, in the province of Yamato, and a poisonous smoke issuing from the cavity struck down with sickness all those who came within its baneful influence; so the people brought quantities of firewood, which they burnt in order that the poisonous vapour might be dispelled. The fire, being the male influence, would assimilate with and act as an antidote upon the mephitic smoke, which was a female influence.[36] Besides this, as a further charm to exorcise the portent, the dance called Sambasô, which is still performed as a prelude to theatrical exhibitions by an actor dressed up as a venerable old man, emblematic of long life and felicity, was danced on a plot of turf in front of the Temple Kofukuji. By these means the smoke was dispelled, and the drama was originated. The story is to be found in the _Zoku Nihon Ki_, or supplementary history of Japan. [Footnote 35: In Dr. Hepburn's Dictionary of the Japanese language, the Chinese characters given for the word _Shiba-i_ are _chi chang_ (_keih chang_, Morrison's Dictionary), "theatrical arena." The characters which are usually written, and which are etymologically correct, are _chih chü_ (_che keu_, Morrison), "the place of plants or turf plot."] [Footnote 36: This refers to the Chinese doctrine of the Yang and Yin, the male and female influences pervading all creation.] Three centuries later, during the reign of the Emperor Toba (A.D. 1108), there lived a woman called Iso no Zenji, who is looked upon as the mother of the Japanese drama. Her performances, however, seem only to have consisted in dancing or posturing dressed up in the costume of the nobles of the Court, from which fact her dance was called Otoko-mai, or the man's dance. Her name is only worth mentioning on account of the respect in which her memory is held by actors. It was not until the year A.D. 1624 that a man named Saruwaka Kanzaburô, at the command of the Shogun, opened the first theatre in Yedo in the Nakabashi, or Middle Bridge Street, where it remained until eight years later, when it was removed to the Ningiyô, or Doll Street. The company of this theatre was formed by two families named Miako and Ichimura, who did not long enjoy their monopoly, for in the year 1644 we find a third family, that of Yamamura, setting up a rival theatre in the Kobiki, or Sawyer Street.
