Tokyo Blackout
Plot. One day, Tokyo and its metropolitan area are suddenly covered by a giant dome-shaped and electromagnetic "cloud" for an unknown reason, and the whole thing seemed to disappear and all communications with the outside of "the cloud" are cut off. Therefore, governments and scientific researchers in various places were extremely shocked and hurriedly organized to study countermeasures. But people are unable to cross "the cloud" into the Tokyo metropolitan area. The Soviet Navy fleet is getting close near Hokkaido, and the U.S. is forcing Japan to form a new government. So an emergency national governor's  meeting was held, and made the national governor's meeting a transitional agency of state affairs. Scientists outside "the cloud" try to rescue 20 million lives in "the cloud" by using artificial high-power electromagnetic jammers. Release. "Tokyo Blackout" was released theatrically in Japan on 11 January 1987 where it was distributed by Toho. It was released in the United States by Toho International on 29 August 1987.
