The Earth is a water planet. Where did the water on the Earth come from? Where did the water of the Moon, another body within the solar system's habitable zone, escape to? Human Spaceology, which studies how the human race might expand out into space, suggests that humans must return to the Moon in order to solve the mystery of its water.

Port and Airport Research Institute (PARI) established the Ocean Infrastructure Research Center on April 1st, 2014, beginning its efforts to provide technological support for "ocean development and promotion of its use." In order to utilize remote islands as bases for offshore development and use, the center looks to support their infrastructure establishment from a technological standpoint, contribute more fully to maritime information within the EEZ, as well as create and develop the fields of ocean floor and deep ocean engineering based on existing port and harbor technologies.

Following the Great East Japan Earthquake, the ocean education activities at Hachinohe City Tanesashi Elementary School were based mainly on conventional classroom learning, but now, study activities conducted in direct contact with the ocean are playing a major role in the school's operations.
Through studies on becoming familiar with, knowing, protecting, and utilizing the ocean, we hope that students will continue to be able to find ways to understand the relationship between humans and the ocean, and realize, think, and take action regarding ways in which humans and oceans can co-exist.
