Several strange occurrences are taking place all over the world including the disappearance of two engineers. Also, former admiral Kosumi is nearly kidnapped along with his secretary, and goddaughter, Makoto Jinguji. The kidnap attempt is thwarted by photographer Susumu Hatanaka and his assistant Yoshito Nishibe. It is later revealed the Mu Empire, which disappeared 12,000 years earlier, are responsible for all the occurrences and are planning to invade the surface world to reclaim their supposed colonies. Also, the Muans manage to steal the I-403 submarine from embittered Captain Jinguji, Makoto's father, and in the process steal the plans for and even greater sub, Atragon (aka Gotengo). As the attacks by the Muans increase the world anxiously asks Jinguji for his help, even his daughter Makoto makes an impassioned plea for him to join the fight against Mu. Unfortunately, Jinguji is still bitter about the defeat of Japan in World War II and won't help. However, the fight becomes personal when Makoto and Susumu, with whom she has fallen in love, are captured by the Muans. Soon Jinguji unleashes his ultimate weapon against the Muans and their giant snakelike guardian Manda. Synopsis by IMDb
[Dodgy](https://nyaa.si/user/DodgyAussie) made a giant 314 GB torrent with 58 Tōhō Kaijū movies in ISO which had this, my favorite movie, in it.
I OCR'ed the subs, deinterlaced and encoded it to HEVC (standard settings, I am not much of an encoder). Audio was copied over. For the production value of the time, it should be more than sufficient. The script was approved on 1963-09-05, merely three months before Tōhō demanded the film be theatrically released. Despite the rush, it was a huge success for Tōhō.
Why do I like this movie? When I was 5 years old, I saw this movie in the kiddie screening of old, cheap B-movies at our local small cinema and fell in love with [Tetsuko Kobayashi, 小林 哲子](https://i.mydramalist.com/kDQ6k_5c.jpg), the empress of Mu. I kid you not, she was my first love. I hope you are as weirded out as I am myself that my first love was someone born over 80 years ago.
DVDrip. Japanese audio in Mono (original) and 5.1, English subs in .srt (default) and vobsub. For feedback, use the comments section below.
