What is MATSRA?

Greetings from the President

Kazumasa Kawasaki

I am Kawasaki, President of NPO MATSRA.
MATSRA is an organization established to operate and manage one of the national government’s demonstration fields, conduct fundamental research in the fishing industry in a sustainable manner, and promote fishery-related science and technology activities, thereby helping to increase the public benefits and promote growth of local community.


As a non-profit juridical organization, we are expected to promote diffusion of energies indispensable to our life and work, and contribute to growth of local community.


As Japan’s first NPO aimed to operate and manage a national demonstration field, we are composed of members from various fields and have a potential to expand our own activities. We may attract increased attention in the near future. We hope this undertaking will make Karats, where an ancient prosperous state of Matsura was located, draw more

Why is the organization named MATSRA?

MATSRA stands for Marine Test Site for Renewable-energy Asia. One of Chinese chronicles, Wei Zhi (the Book of Wei) explains in its chapter of Wa, which is the ancient name of Japan as used by Chinese dynasties, that a state named Matsura covered an area that is currently located in Karatsu City in Saga Prefecture.

Purpose of Foundation

Energy is a lifeline indispensable to our life.

The Great East Japan Earthquake in 2011 made us keenly aware of the importance of energy. People have set a high expectation of recyclable energy, which is the type of energy source that taps energy from nature.

The waters in the Iki Channel facing the ocean off the Kabeshima Island in Karatsu City are the sites of a “demonstration field” for marine energy selected by the national government.


Under harmonious relations among the national government, the Saga prefectural government, and related parties, NPO MATSRA conducts various activities, with an aim to contribute to the promotion of public benefits or growth of local community, and realize such aim through its operation and management of a demonstration field; promotion of science and technology, agricultural, fishing, and rural communities or hilly or mountainous areas, and fundamental research on the sustainable fishing industry.

To operate and manage the national government’s demonstration field, it is necessary to establish cooperation between the fishery, which uses waters, and energy.
It takes a new organization, composed of human resources who are well informed of each of the related fields, or fishery, marine energy, and industry, to contribute to the further growth of local community, in addition to a fair and appropriate operation and management of the demonstration field. Such an organization is mainly engaged in non-profit activities. Hence, a specified non-profit juridical organization (NPO), whose aim is to promote public benefits and growth of local community, is considered appropriate.


MATSRA was, thus, established as an NPO.
