One of the main principles underlying the Basic Act on Ocean Policy and the Basic Plan on Ocean Policy of Japan is 'Comprehensive Governance of the Oceans.' To achieve this principle, it is important to build up a network of far-remote-islands which consist of the core centers of 200-mile radius sea areas first and secondly the artificial bases of floating structures, and thirdly the amphibian plane for effective management of EEZ.

In the Basic Plan on Ocean Policy, much mention is made of the healthy development of marine industries and the securing of maritime transport, but submarine cables are mostly ignored. For the maritime state, as well as the information technology state of Japan, the conveyance of information is of equal importance to the transport of material goods. This article offers a supplementary explanation of the Basic Plan from the submarine cable industry's perspective.

I would like here to introduce the man who laid the foundations for the Japanese Navy.
