Doraemon: Nobita and the Birth of Japan is the 10th film installment in the Doraemon franchise, as well as the first one to release in the Heisei era.
Nobita and friends have had it with their busy schoolwork, exams, and wishes to take a retreat for a while. To their surprise, Doraemon is on their side this time, after Nobita's parents, the Nobis, brought a pair of guinea pigs into the house, given Doraemon's usual crippling phobia of rodents. One thing leads to another and the gang then decides to hop into the Time Machine in Nobita's drawer, Time Travel to the prehistoric period, and live over there for a few weeks.
And then they rescue a young boy named Kukuru (an Identical Stranger to Nobita) who's the Sole Survivor after his tribal home was destroyed by living robots. Before discovering an ancient, sinister conspiracy threatening to rewrite history.
The film was released in Japan on March 11, 1989. A remake is released in 2016.
This movie provides examples of:
- Actionized Adaptation: The 2016 remake have far more action scenes, fights, and large-scale battles than the manga or original anime.
- Adaptational Badass: Everyone in the 2016 version.
- Gigazombie from the original manga and anime is a rather generic time-traveling villain, but in the remake he's a megalomaniac who wants to rewrite history and has a nuke at his disposal.
- Tsuchidama puts up a far better fight against Doraemon-as-Dorazombie in the finale.
- Nobita in the manga and original anime needs to be saved by the Time Patrol after being stranded in the blizzard, and later reunites with his pets. In the remake he survives through sheer will and awakes before his pets who found him.
- Kukuru (and the rest of the tribespeople) doesn't get to do much in the original story's climax, but in the remake they managed a Slave Liberation and battles Gigazombie's Kurayami Tribe, with Kukuru helping the heroes in the finale.
- Shizuka, Gian and Suneo managed to help in shootouts against Gigazombie's robots with the Instant Adhesive Glue Gun (in the original, Doraemon does all the shooting). Suneo and Gian notably shoots Gigazombie's staff from his hands just in time to prevent him from using it again on Nobita.
- Inverted with the Time Patrol in the remake, who goes from arresting Gigazombie and saving everyone to doing jack squat, arriving after all the action is over.
- Adaptation Expansion: The anime series has an earlier short with a similar premise, where Nobita and friends managed to convince Doraemon to bring them into the past to escape their current life, only to run into volcanoes, natural disasters and saber-toothed tigers. No time-travelling supervillains or clay robots in that one, though.
- Big Bad: Gigazombie is the ruler of the Dark Tribe.
- Big Damn Heroes:
- Nobita actually pulls an impressive one at the end; the only character who escaped capture from Gigazombie's minions, Nobita returns with his pets, the pegasus, gryphon and dragon, and epically barges into the Dark Tribe's lair to save all his friends. Including Doraemon who just lost a fight against Gigazombie.
- The Time Police who serves as The Cavalry in the manga and anime (not the remake), arresting Gigazombie, disbanding the Dark Tribe, and saving Nobita and friends after they're trapped by a cave-in.
- Cool Pet: Nobita, being assign to create "pets" using Doraemon's DNA mixing machine, decide to create a pegasus, a gryphon and an oriental dragon. They serve as steeds and are handy in scaring away minions of the Dark Tribe.
- Deity of Human Origin: The main villain, Gigazombie, was just an ordinary human scientist, albeit one from the 23rd Century. He uses Time Travel to project himself to the prehistoric era, took over the Dark Tribe, and makes himself their ruler as he attempts to enslave entire surrounding tribes to change the world as he sees fit.
- Curb-Stomp Battle: Doraemon vs. Gigazombie, with Gigazombie on the winning side. Why? Because Gigazombie's from the 23rd-Century - a hundred years ahead of Doraemon.
- The Faceless: Gigazombie, whose face is always hidden behind his scary-looking tribal mask, which the Dark Tribe worships as a God. It finally comes off whhen the Time Police arrives to apprehend Gigazombie, knocking him flat and the mask off... and it turns out Gigazombie looks like an ordinary schmuck beneath it.
- Famous Ancestor: According to the 5th chapter of Chinpui, Kukuru is the ancestor of Eri Kasuga.
- Foreshadowing: Noticed how Tsuchidama sounds very robotic and has technology that didn't exist the past? These are a hint that Gigazombie is a time criminal who brainwashed the Dark Tribe.
- Identical Stranger: Kukuru is an exact doppelganger to Nobita.
- Living Statue: The living Dogu statues ruling the Dark Tribe appears to be these... until after Doraemon destroys one and collects a fragment from it, he then discover it to be made of magnetic dust, making them Mecha-Mooks instead.
- Our Gryphons Are Different: The Gryphon sidekick in this film, for instance? It's made by a gadget which can literally create life, by analyzing data from different animals. Nobita decide to insert data from an eagle and a lion at the same time, and cue the baby gryphon's birth.
- Pegasus: One of three pets created by Nobita (the other two being a Gryphon and an oriental-looking dragon) when he's assigned to create animals.
- Pulling Themselves Together: Gigazombie's robots, which initially appears to be clay Dogu statues, turns out to be made of high-tech ceramic magnets - upon being shattered, they instantly reform. The final chase between Doraemon and gang against Gigazombie's robots instead have Doraemon using the Instant Glue Gun to stick them on the spot.
- Robot Master: Gigazombie created his own order of Mecha-Mooks to enforce his rule over the Dark Tribe. Despite looking like ceramic Dogu statues, they're actually mechanical.
- Surprisingly Realistic Outcome : Nobita decides to make a makeshift place to live by using one of Doraemon's gadgets and tries various times to settle his moving house, however, as soon he's installed, he's kicked out and forced to remove his house due to violating land property ownership laws.
