Mothra vs. Godzilla

Mothra vs. Godzilla , Mosura tai Gojira? is a 1964 Japanese science fiction kaiju film produced by Toho. Directed by Ishir Honda, and featuring special effects by Eiji Tsuburaya, the film starred Akira Takarada, Kenji Sahara and Hiroshi Koizumi. The fourth film in the Godzilla series, it was the first in which Toho began bringing in monsters from other productions, having Godzilla cross paths with Mothra. This trend would continue later in the same year with Rodan, in Ghidorah, the ThreeHeaded Monster.

News reporter Ichiro Sakai and photographer Junko Nakanishi take pictures of a wreckage caused by a typhoon. They uncover a strange, bluishgray object in the debris, not knowing its significance. Later that day, a giant egg is discovered on the shore. The local villagers salvage it, and an entrepreneur of Happy Enterprises named Kumayama buys the egg from the local villagers. Instead of letting scientists study the egg, Kumayama wants to make it into a large tourist attraction. Later, Sakai and Nakanishi are informed that the strange object they found is extremely radioactive. It is later hinted that this is a skin particle from Godzilla.While Sakai, Nakanishi, and scientist Professor Miura are discussing the egg at a hotel, they discover Kumayama checking in. Kumayama meets with Jiro Torahata, the head of Happy Enterprises. They are unexpectedly confronted by tiny twin girls known as the Shobijin and try to capture them. The Shobijin escape and meet with Sakai, Nakanishi and Professor Miura. They explain that the egg belongs to Mothra. If the egg hatches, the larva though they have no quarrel with man will still cause great damage looking for food. The trio agree to help. ........
