The permanent partitions within the house are made in various ways. In one method, bamboo strips of various lengths take the place of laths. Small bamboos are first nailed in a vertical position to the wooden strips, which are fastened from one upright to another; narrow strips of bamboo are then secured across these bamboos by means of coarse cords of straw, or bark fibre ([fig. 4]). This partition is not unlike our own plaster-and-lath partition. Another kind of partition may be of boards; and against these small bamboo rods are nailed quite close together, and upon this the plaster is put. Considerable pains are taken as to the plastering. The plasterer brings to the house samples of various-colored [pg 32] sands and clays, so that one may select from these the color of his wall. A good coat of plaster comprises three layers. The first layer, called shita-nuri, is composed of mud, in which chopped straw is mixed; a second layer, called chu-nuri, of rough lime, mixed with mud; the third layer, called uwa-nuri, has the colored clay or sand mixed with lime,—and this last layer is always applied by a skilful workman. Other methods of treating this surface will be given in the chapter on interiors.
Many of the partitions between the rooms consist entirely of light sliding screens, which will be specially described farther on. Often two or more sides of the house are composed entirely of these simple and frail devices. The outside permanent walls of a house, if of wood, are made of thin boards nailed to the frame horizontally,—as we lay clapboards on our houses. These may be more firmly held to the house by long strips nailed against the boards vertically. The boards may also be secured to the house vertically, and weather-strips nailed over the seams,—as is commonly the way with certain of our houses. In the southern provinces a rough house-wall is made of wide slabs of bark, placed vertically, and held in place by thin strips of bamboo nailed cross-wise. This style is common among the poorer houses in Japan; and, indeed, in the better class of houses it is often used as an ornamental feature, placed at the height of a few feet from the ground.
Outside plastered walls are also very common, though not of a durable nature. This kind of wall is frequently seen in a dilapidated condition. In Japanese picture-books this broken condition is often shown, with the bamboo slats exposed, as a suggestion of poverty.
In the cities, the outside walls of more durable structures, such as warehouses, are not infrequently covered with square tiles, a board wall being first made, to which the tiles are secured by being nailed at their corners. These may be placed in diagonal [pg 33] or horizontal rows,—in either case an interspace of a quarter of an inch being left between the tiles, and the seams closed with white plaster, spreading on each side to the width of an inch or more, and finished with a rounded surface. This work is done in a very tasteful and artistic manner, and the effect of the dark-gray tiles crossed by these white bars of plaster is very striking ([fig. 25]).

As the fire-proof buildings, or kura, are often used as dwelling—places, a brief mention of their structure may be proper here. These buildings are specially designed for fire-proof storehouses. They are generally two stories in height, with walls eighteen inches to two feet or more in thickness, composed of mud plastered on to a frame-work of great strength and solidity. The beams are closely notched, and bound with a coarse-fibred rope; and small bamboos are closely secured to the beams. Short coarse-fibred ropes, a foot in length, are secured in close rows to the crossbeams and uprights. All these preparations are made for the purpose of more securely holding the successive layers of mud [pg 34] to be applied. As a preliminary to this work a huge and ample staging is erected to completely envelop the building. The staging, indeed, forms a huge cage, and upon this straw mattings are hung so that the mud plastering shall not dry too quickly. This cage is sufficiently ample to allow the men to work freely around and beneath it. Layer after layer is applied, and a long time elapses between these applications, in order that each layer may dry properly. Two years or more are required in the proper construction of one of these fire-proof buildings. The walls having been finished, a coat of plaster, or a plaster mixed with lamp-black, is applied, and a fine polished surface, like black lacquer, is produced. This polished black surface is made by first rubbing with a cloth, then with silk, and finally with the hand.
A newly-finished kura presents a remarkably solid and imposing appearance. The roofs are of immense thickness, with enormous ridges ornamented with artistic designs in stucco, and the ridges terminating with ornamental tiles in high-relief. The fine polish of these buildings soon becomes impaired, and they finally assume a dull black or slaty color; sometimes a coat of white plaster is applied. Upon the outside of the wall a series of long iron hooks are seen; these are to hold an adjustable wooden casing which is often used to cover the walls, and thus to protect them from the eroding action of the elements. These wooden casings are placed against the buildings, proper openings being left through which the iron hooks project, and long slender bars of wood stretch across the wall, held in place by the upturned ends of the iron hooks, and in turn holding the wooden casing in place.
The windows of the buildings are small, and each is closed either by a sliding-door of great thickness and solidity, or by double-shutters swinging together. The edges of these shutters have a series of rabbets, or steps, precisely like those seen [pg 35] in the heavy doors of a bank-safe. At the time of a fire, additional precautions are taken by stopping up the chinks of these closed shutters with mud, which is always at hand, ready mixed for such an emergency. These buildings, when properly constructed, seem to answer their purpose admirably; and after a conflagration, when all the surrounding territory is absolutely flat;—for there are no tottering chimneys or cavernous cellars and walls to be seen, as with us,—these black, grimy kura stand conspicuous in the general ruin. They do not all survive, however, as smoke is often seen issuing from some of them, indicating that, as in our own country, safes are not always fire-proof.
