is a 1956 Japanese kaiju film directed by Ishirō Honda, with special effects by Eiji Tsuburaya. Produced and distributed by Toho Studios, it was Toho's first kaiju film to be shot in color, and is one of several giant monster films that found an audience outside Japan. The film stars Kenji Sahara and Yumi Shirakawa. In the United States, it was released in 1957 as Rodan! The Flying Monster!. Plot In the small mining village of Kitamatsu, near the foothills of Mount Aso on the southern Japanese island of Kyushu, two miners have gone missing. The two men, Goro and Yoshi, had brawled earlier that day (the film implies that the two have violently quarreled for some time) and after they entered the mine to start their shift, the shaft had flooded. Shigeru Kawamura, a tunneling and safety engineer at the mine, heads below to investigate and discovers Yoshi's lacerated corpse. Above ground, a doctor examines Yoshi, and discovers the cause of death to be a series of deep gashes caused by an abnormally sharp object. Some of the miners and their families begin to discuss the possibility of the involvement of Goro in the death. Two local miners and a policeman are later attacked and slain by an unseen assailant in the flooded shaft. Their bodies are recovered and examined, and the doctor announces that they were also killed by a sharp object. That night, Shigeru and his fiancée Kiyo are attacked by a Meganulon, a giant species of larval insect at Kiyo's home. The police start hunting the creature, and it kills two officers before escaping into the mine. The police and Shigeru notice that the officers' wounds match the wounds of the murdered. Shigeru, accompanied by police and soldiers, heads into the mine, where they discover the butchered body of Goro and are chased by the insect monster. Shigeru crushes the creature with runaway mine carts, but after another insect monster appears, the tunnel caves in, trapping Shigeru in the mine. The next day, Dr. Kashiwagi identifies the giant insect as a Meganuron, an ancient species of dragonfly larvae. An earthquake suddenly strikes the area, and rumors begin to circulate that Mount Aso might be on the verge of an eruption. When the police head to the volcano to investigate the damage caused by the earthquake, they discover that the only road to the mines has collapsed.
