The traditional industrial areas along the coast are

The steel industry of Seto Inland Sea Industrial Zone in Japan belongs to the coastal industrial layout.

In order to make full use of cheap shipping conditions, the industries that set up factories in coastal ports are all coastal industries.

The characteristic of coastal industry is that it needs a lot of raw materials and fuels, and its products are relatively heavy. In the whole production process, freight accounts for a large proportion in the production cost. This kind of industry is located in the coastal port area, which reduces the transportation cost to the maximum extent and obtains the best benefit.

Japan's steel industry needs to import raw materials and fuels, and its products depend on the international market. However, Japan has a tortuous coast, numerous bays, many excellent natural ports and developed shipping. In order to facilitate the transportation of raw materials, fuels and export products and reduce freight rates, Japan has formed a "coastal" industrial zone.
