According to UNESCO's website, the site testifies the successful transfer of Western Industrialization to a non-Western nation. From the middle of the nineteenth century to the early twentieth century, Japan was in the rapid industrialization, supported by the key industrial sectors such as shipbuilding, iron and steel, and coal mining.
If the specific sites can speak, it can tell us how Japan has achieved its technological superpower from its humble beginnings-- from trial and error experimentation aided by Western textbooks, followed by the importation of Western technology, until the full-blown industrialization where the Japanese were able to actively adapt the Western technology suited to their needs.
