The refractory brick factories in Japan are concentrated especially in two districts -Wake and Nobi districts. In Japan, 85% of the factories in this industry are producing the refractory bricks made from clay, and this concentration is because the factories are built in the producing areas of raw material to insure the supply of raw material at low cost (Fig. 1, 4 table 1, 2).<BR>Refractory brick is a kind of the production goods and at the same time a kind of the raw material. And this industry is subordinated to the user of the products, chiefly to the iron and steel industry, producing respectively a little quantity of refractory bricks of different types (Fig. 6, table 3). Such character of this industry gives birth to differrent features of the factories in accordance with each user, and many subcontractors producing low-class refractory bricks (Fig 10). These small scale subcontractors are concentrated in the Nobi district, where both the labour and the material costs are relatively low (Fig 3, 8, 9), while many of the larger factories of high-class refractory bricks are concentrated in the Wake district, situated near the old and large market of Osaka district (Fig 2, 3, 6, 7).<BR>Some other factories are distributed in the market areas ; the eastern Setouchi, Tokyo and its neighbourhood, and Kitakyushu City (Fig 1, 6). Strong demand for the stable supply of the products on the part of the users is the main factor of the distribution of the latter type (Fig 11).<BR>Thus, the above mentioned distribution in the raw material areas and the market areas brings about the dense distribution of the factories in the Industrial Belt along the Pacific side of Japan (Fig 1).
