RIO DE JANEIRO (Jiji Press)--Japan will provide a total of 6 billion dollars in official development assistance over three years from fiscal 2013, Foreign Minister Koichiro Gemba said at the U.N. Conference on Sustainable Development, dubbed Rio+20.

Through the aid, the nation will help developing countries establish measures to minimize damage from natural disasters and introduce renewable energy.

Gemba said in a speech that Japan wishes to share its disaster prevention technologies and know-how with developing countries to create communities resistant to disasters. Such knowledge was acquired from the experience of the March 2011 earthquake and tsunami, he added.

The minister stressed, "All countries need to work together toward the transition to a green economy using superior energy and resource efficiency."

He said Japan plans to send about 10,000 experts to developing countries over the next three years to support their transition to a green economy in which both economic growth and environmental protection are realized.

A Japanese pavilion was set up along the sidelines of the Rio+20 conference to showcase the country's reconstruction efforts after the March 2011 disasters. In a separate speech at the pavilion, Gemba said the three hardest-hit prefectures of Fukushima, Miyagi and Iwate are striving to overcome their hardships so they can stand on their own feet again.

It is also Japan's duty to share the nation's knowledge, experience and the process of reconstruction with the rest of the world, Gemba said.

At the facility, local government officials from the three Tohoku prefectures showed video footage of their reconstruction efforts. They also introduced local dishes and sake to visitors.
