Kenichiro was a journalist planning to write a book on the origins of Godzilla. He theorizes that Godzilla is a mutated version of a dinosaur found on Lagos Island in World War Two. He approached one of the surviving members of the military group that was stationed there at the time. After learning about Godzilla from this man, Kenichiro is summoned to the Japanese Prime Minister's office. On arrival, He sees his colleague Professor Mazaki has been summoned as well, and they are both issued in to the office. Once they are inside, they are introduced to Miki Saegusa, another person who was summoned. It is then revealed to them that some humans from the future have asked for them to aid them in their quest to eliminate Godzilla from history. Kenichiro was asked to accompany them due to his publishing a book on the creature. They travel back in time to Lagos Island, and wait for the fighting to die down. Kenichiro has no role in relocating the Godzillasaurus on the island. When the group returns to the present, the Futurians reveal that while they have eliminated Godzilla, King Ghidorah has taken his place. Upon learning this, Futurian Emmy Kano runs away to warn the Japanese government, seeking refuge with Kenichiro. The two are attacked, and Emmy is taken away. Kenichiro is later taken to the Futurian mother-ship to aid Kano in sabotaging its control of the rampaging King Ghidorah. Kenichiro helps to create Mecha-King Ghidorah by supporting the notion that Ghidorah's corpse should be rebuilt with Futurian technology. At the close of the film Emmy Kano reveals that Kenichiro is her ancestor.
