North Korea has built a new facility to increase efforts to educate its people on the "history of aggression" by Japan and the United States.

The National House of Class Education, with about 1,700 photos and thousands of other items showing the "aggressive nature" of Japan and the United States, opened in late June in Pyongyang and was shown Friday to Kyodo News, the first foreign media outlet to see it.

The three-story building has nearly 4,000 sq. meters of floor space and is the first facility in Pyongyang to focus on anti-Japan education, according to North Korean officials.

The first floor is for anti-U.S. education and the second is exclusively related to Japan.

It was said that the facility is especially intended for younger North Koreans who have no direct memories of Japan's colonization of the Korean Peninsula or the Korean War.

North Korea's state-run media has said the center will be a place to help its people clearly realize who their main enemies are and strengthen their will to exact revenge on them.

"If we forget the history of aggression, it can be repeated. We need to teach a new generation not to forget it," Kim Hyong Chol, 60, head of the new facility, said, adding that it has generated a stream of visitors since its opening.
