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.

Approximately 100 tons of dry ice and various other materials were used to depict the clouds.  All staff wore dust masks when shooting using fly ash, a building material.  In the scene where people are swallowed by the cloud, high-definition video was used for only 20 seconds.  The EP-3E reconnaissance aircraft is a modification of the P-3C aircraft model used in The Return of Godzilla.

In 1964, Komatsu published the short story Object O (物体O).  The story involves a mysterious ring-shaped object 200 kilometers high and 1,000 kilometers wide, which falls around Osaka, cutting it off from the outside world.  In contrast with Tokyo Blackout, Object O focuses on events within the ring.

Komatsu wrote the novel in serialized form, published among Hokkaido Shimbun, Chunichi Shimbun and Nishinippon Shimbun from December 1983 to December 1984.  The book was published by Tokuma Shoten in 1985 and became a bestseller that year, exceeding 1.5 million copies sold.  This made it the second best-seller for Komatsu after The Sinking of Japan.

While the film emphasizes family ties and human drama, the novel has a strong political focus, emphasizing crisis management and Japan’s vulnerability.^[5]

The novel begins with Tatsuya Asakura, manager of the planning and general affairs section at the S Heavy Industries Tokyo Headquarters, as he has an unusual experience returning to Tokyo on the Tokaido Shinkansen.  Communications and traffic within Tokyo suddenly stop, and the Shinkansen stops at Hamamatsu Station.  Here, Asakura meets his friend, JASDF officer Sakuma.

At 7:00 AM that day, a cloud with a 60-kilometer diameter radiates from the center of Tokyo, completely enveloping the city to a height of 1,500 meters.  Gozo Otawara, an advisor to S Heavy Industries with PHD’s in science and engineering, works with the Central Research Institute of S Heavy Industries and Jonan Medical University to investigate the cloud where Yokohama New Road crosses National Route 16.  Tamiya, a classmate of Asakura’s and editor-in-chief of  Kitakyushu’s local newspaper Seibu Shimpo accompanies the investigation.   

The cloud is discovered to consist of water vapor and high levels of ozone and argon.  It resists all attempts to penetrate it, including bullets.  Humans cannot walk more than 20–30 meters inside before being stopped.  Radio waves also don’t reach inside the cloud, so the condition of Tokyo’s inhabitants is unknown.

That evening, at the Atsugi base near the Central Research Institute, an emergency meeting is held between the Self Defense Force and US Forces stationed in Japan, involving United Nations and Ministry of Foreign Affairs representatives.  The US forces stationed in Japan urge the Japanese to rebuild the government as soon as possible.  Tamiya, inspired by the seriousness of the situation, travels to the Kansai headquarters of A Shimbun and works to rebuild the Japanese government.

10 days after the cloud’s appearance, an emergency national governor’s conference is held in Nagoya, establishing Hyogo Prefecture Governor Komuro as the temporary chief representative.  The organization is formed by a coalition of prefectures and ordinance-designated cities.  It consists of prefectural governors, deputy governors, prefectural assembly chairs, mayors of ordinance-designated cities and representatives of Tokyo, Kanagawa and Saitama prefectures.  The basis for legal legitimacy is emergency evacuation under international law, with the premise that the Japanese government is out of touch, but still in existence.

Simultaneously, the cloud begins emitting powerful particle beams, damaging or destroying any aircraft or satellites passing above it.  An EP-3E reconnaissance aircraft is directly hit by a particle beam, destroying all electronic equipment and killing one crew member from radiation exposure.  The United States researches the cloud’s abilities for military purposes, while the Soviet Union detains a Japanese diplomat to increase external pressure on the country.

In January of the following year, the Soviet Union sends a large fleet to Hokkaido.  A huge earthquake occurs off the coast of Nemuro, and the Soviet fleet is destroyed by a tsunami.

At the end of March, about four months after the cloud’s appearance, an international survey of the cloud is conducted.  It is determined that the cloud is an automated surveillance device sent by intelligent extraterrestrial life.  Shortly afterward, in early April, the cloud disappears as suddenly as it appeared.

Tokyo Blackout was released theatrically in Japan on 11 January 1987 where it was distributed by Toho.^[1] It was released in the United States by Toho International on 29 August 1987.^[1]
