Film / Big Man Japan

Go To

Dai-Nihonjin, released internationally as Big Man Japan is a tongue-in-cheek 2007 Japanese Toku film written and directed by Hitoshi Matsumoto (of the Downtown comedy duo fame), who also stars as the somewhat-eponymous protagonist. The film utilises a number of styles including Mockumentary, Kaiju and mild satire to build its laughs.

The story follows Masaru Daisatô, an almost-ordinary middle-aged man, and a documentary being made about his life. Why is such a seemingly non-descript man deserving of the effort? Because he is able to take in great electrical surges to become a gigantic warrior whose purpose is to defend Japan from some truly bizarre monsters, that's why.

Sadly, this inherited superpower is no longer treated with the same public appreciation as it once was. Daisatô's senile grandfather is spending his last days alone in a retirement home, and Daisatô himself has been forced to have his fights televised and judged by the unpleasable populace while he lives alone in a rather decrepit house. He rarely gets to see his daughter and it seems he's a target of green activists and others for the collateral damage he tends to cause. Of course, he doesn't have much of a choice in the matter and by the end of the film, it seems his time has come at the hands of a particularly dangerous monster.


The final product has recieved mixed reactions, but many were at least overjoyed with the surreal comic touch of the film, if not perhaps so with the near dramatic elements. Fans of Matsumoto's may be able to see recurring themes re-emerging here, as well as being able to see the faces of some of his occasional collaborators.

This film provides examples of:

  • Affectionate Parody: Matsumoto is an avowed fan of Toku/Kaiju movies and shows and the film deconstructs and parody many tropes within the genre.
  • America Saves the Day: The Super Justice Team ganging up to defeat the devil monster.
  • Apathetic Citizens: Big Man Japan is destined to protect Japan... but who cares about that when the (televised) fights are so boring?
  • Beast with a Human Face: Most of the Kaiju have human faces, yet have varying degrees of intelligence.
  • Advertisement:
  • Big Damn Heroes: Daisato's senile grandfather suddenly appears giant sized to help Daisato fight the Devil Monster. Unfortunately, he fails.
  • Bittersweet Ending: Daisato still has his stresses in life and got the tar beaten out of him by the devil monster whilst being outshine by another superhero force. But he does have some friends in the Super Justice Team who treat him to dinner afterwards.
  • Children Are Innocent: The public gets angry at Daisato for accidentally killing an infant kaiju.
  • Combination Attack: The Super Justice Team invite Big Man Japan to join hands with them in order to fire a beam at a monster he couldn't beat. BMJ moves his hand away briefly and notes that the beam isn't any weaker without him.
  • Corporate-Sponsored Superhero: In-universe, Daisatô is forced to have adverts plastered all over Big Man Japan to gain revenue. He's even told by his agent to be careful when fighting a monster so as not to have an advert obstructed.
  • Curb-Stomp Battle: Big Man Japan versus the devil monster, as well as said monster versus The Super Justice Team.
  • Cursed with Awesome: Daisato and his family.
  • Deus ex Machina: When all seems lost for Daisato at the end, the Super Justice Team pops out of nowhere to defeat the Devil Monster.
  • Dramedy
  • Eagleland: The Super Justice Team is type 1.
  • Expy: The Super Justice Team are basically the Ultra Brothers with a Eagleland flavor.
  • Eyes Do Not Belong There: One of the monsters has its one eye in what's otherwise a more... private area.
  • Gainax Ending: The CGI animation is replaced with People in Rubber Suits, an American superhero family shows up and beats the tar out of the devil monster, and he has dinner with them over the credits. It's supposed to symbolize the decline of Japan's place in the world or something but... What.
  • Hero with Bad Publicity: Daisatô is inundated with criticism, from insulting graffiti outside his house to a candlelit vigil for one of the monsters.
  • He Who Fights Monsters: The opinion of just about everyone in Japan when it comes to Big Man Japan.
  • Kaiju: A tribute/parody.
  • Knight of Cerebus: The Devil Monster is the only serious monster of the film that is a genuine threat to Daisato's life and the tone becomes intense when it enters the scene.
  • Loners Are Freaks: In a more literal way than normal.
  • Magic Pants: Defied. Big Man Japan's purple pants are really that huge, meaning before growing he has to stand inside them while they're stretched out by tall poles.
  • Mind Screw: Perhaps unintentionally at times, but the ending takes it to a more comedic extreme.
  • Our Monsters Are Weird
    • The Strangling Monster: What looks like the unholy offspring between a giraffe and the Michelin Man. It has a comb-over and two arms conjoined by cables, which it uses to squeeze stuff. Also, it defecates harpoons.
    • The Leaping Monster: A human head with one reptilian leg. It leaps around yelling "Sei!"
    • The Evil Stare Monster: It's best described as a headless tarsier with an eyeball on its... earthworm penis.
    • The Stink Monster: Actually two monsters. One looks like a mutant jellyfish with a human head. The other is just... creepy.
    • The Child Monster: A talking fetus with a full head of hair
  • Pokémon Speak: The leaping monster. SEI!!!
  • Stylistic Suck: When the Super Justice Team arrives to save the day, the special effects gets a deliberate and obvious downgrade.
  • Think of the Children! : Big Man Japan accidentally kills a baby monster. People go apeshit.
  • Women Are Wiser: A husband and wife monster duo attack midway through the film. The wife is an lazy but intelligent Deadpan Snarker, the husband an energetic Keet who does not speak.
