Launching after the closure of the Heisei series, Godzilla Island was, at heart, a product tie-in. The show did boast an impressive array of kaiju; however, and this is where the show's notoriety comes from, the kaiju were almost entirely "brought to life" by small malleable figures that used the mold from the Bandai toys. Some exceptions included Mothra Leo, Dogora and Godzilla's son.

The show is set in the year 2097, with most of the Earth's monsters being allocated to a island out in the Pacific Ocean. The lead villains are the Xilien, represented by two actresses with their leader being seen as a fiery floating head called the Giant Emperor. Godzilla Island, in general, returned the franchise back to its late 1960's through mid-1970's roots. Godzilla was no longer a monster of solidarity, and would fight alongside kaiju like Rodan and Mothra. The show also saw the return of one of Toho's most famous mechs: the Gotengo, which had a new variation called the Gyotengo featured here.

Godzilla Island's roster of kaiju included: Godzilla, Mothra, King Ghidorah, Rodan/Fire Rodan, Mechagodzilla, Anguirus, Mothra Leo, Gigan, Hedorah, Battra, SpaceGodzilla, Destoroyah, Baragon, King Caesar, Moguera, Mecha-King Ghidorah, Megalon, Gorosaurus, Kamacuras, Dogora, Kumasogami (called Dororin) and more. The show also introduced numerous variations on the pre-existing kaiju, including a medic Jet Jaguar, a black Mechagodzilla ('74) a red Jet Jaguar and a bluish-pink Hedorah.

Godzilla Island, in its entirety, ran for almost a year, playing a new episode every weekday. Each individual show played in a 3 minute time slot, so it would take two full week's worth of episodes to account for a running time close to a normal TV show episode.

Music for the program was both original and comprised of stock music from Toho films, while the title song was done by The Edge.
