Everywhere, excepting in Yezo, the cultivation of rice preponderates, especially in the northern part of the principal island, mainly because the climate is elsewhere too cold to allow of any other crop being sown during the winter and spring. Barley and wheat are grown mainly in the centre of the great island of Nippon, rye in the western parts of the same island, and also in the two southern islands of Shikoku and Kiu-Siu, the last-named of which produces sweet potatoes in abundance. These were originally imported from Java to Satsuma, and are still called _Satsuma-imo_, or Satsuma potatoes. Tobacco, which was introduced by the Portuguese in the sixteenth century, and which is universally used all over the islands, being one of the few customs the Japanese have retained from their first contact with Europeans, is cultivated everywhere, except, perhaps, in the north. The mulberry-tree grows exclusively in the mountainous regions of the centre, and only in very small quantities in the north. Tea will be met with, on the other hand, only in the plains, and at the foot of the lower ranges of hills. From the windows of the train which passes from Tokio to Kioto, and principally in the environs of this last-named town, as also of Osaka and Nara, one sees extensive tea-plantations lifting their deep, green foliage from the rice-fields. As may well be imagined, owing to the smallness of his tenement, the Japanese peasant is by no means rich, and has to live on very little. In the plains he subsists mainly on rice boiled in water, precisely as do the workpeople in the towns, a little fish seasoned with _soy_, or Japanese sauce, flavours this very simple menu, which also includes a few eggs, and occasionally a chicken, a little game, or a wild duck. In the mountains, where the people are very poor, and rice is considered a luxury, barley and millet are sometimes substituted. The fisher-folk replace this almost exclusively vegetarian diet by the produce of their work. Even among well-off people in the towns the principal dish at dinner consists of boiled rice. During meals the usual drink is hot _saké_, which the guests offer each other in little cups with a good deal of polite ceremony. This very weak form of brandy is distilled from rice, and about 150,000,000 gallons of it are consumed annually. The other great Japanese drink is green tea.
