Please comprehensively analyze the main reasons why Japanese industry is concentrated in the Pacific coast and the inland sea coast of Seto.

Japan is a world power with winding coastline, numerous good ports and developed economy. However, due to its narrow geographical area and lack of resources, it is a small country with strong dependence on foreign countries. Therefore, its industry is mainly distributed in the narrow strip along the Pacific coast and the inland sea coast of Seto, which is convenient for the import of raw materials and the export of products.

So the answer is:

(1) Japan is poor in resources, mainly engaged in processing trade, importing a lot of raw materials and fuels and exporting industrial products. (2) Island country, with many excellent harbors, winding coastline, convenient conditions along the Pacific coast and convenient import and export trade.
