An amazing 38 trillion cubic meters of river water flows into our oceans each year, almost all of which is rainwater, created through the evaporation of our seas. Through the continual circulation of this huge amount of water from land to sea, the many problems carried by rivers are swept straight out to sea without resolve, seriously affecting our oceans and their resources. To return our oceans to the former pleasure of yesteryear is going to require a serious reconsideration of the relationship between them and our rivers.

In the 20th century the Japanese fishing industry sought fishing grounds throughout the world. Now, in the 21st century it is being urged to rebuild the fishing industry in and around the waters of Japan. Perceiving the priceless benefits bestowed in the water that links our rivers, forests and blessed land, leading fishermen are putting their efforts into a "Forests that Cultivate Fertile Oceans" campaign. The topics "Forests: The Oceans Partner", "Fish Possessed by Plantations" and "Forest Building by the Fishing Community" introduce this campaign.

The greatest achievement of waterfront developments is the way they have turned the attention of urban dwellers towards the sea and created a scenic balance between ocean and city. However, such developments up to this day have hardly been undertaken with a true understanding of the environmental features of the shoreline and leave us in much anticipation of a new development phase (water front developments for the next generation). Meanwhile, although Mega-Float has the potential to create new coastal scenery for urban centers, its path to actual implementation will be strictly limited if it is merely characterized as alternative space to land.
