There are filmmakers who make films, and then there are filmmakers who seem to have wandered into a film laboratory, knocked over several shelves of chemicals and decided to see what happened.

Yoshihiro Nishimura was very much the latter.

With Geisha War, the Japanese cult filmmaker delivers one final eruption of blood, absurdity, political provocation and gloriously impractical visual effects. It is a film that frequently appears less interested in whether its story makes sense than in whether the next image can possibly be more outrageous than the last.

The answer, more often than not, is yes.

Set in the historic pleasure district of Yoshiwara, Geisha War pits an American gangster and his associates against the local community, led by Kiki, a ramen vendor who finds herself caught up in the struggle to protect the district from outside control. The basic premise provides Nishimura with an excuse to stage a collision between American gangster mythology, Japanese popular culture and his own particular brand of cinematic insanity.

And insanity is certainly the operative word.

Nishimura’s cinema has never been particularly interested in restraint. From Tokyo Gore Police to Helldriver, his films transform bodies into weapons, flesh into sculpture and practical effects into a kind of gleeful visual assault. Geisha War carries that tradition forward with an arsenal of bizarre weaponry, outrageous transformations and fountains of artificial blood. FilmInk describes the film’s visual approach as a combination of solid practical gore and cartoonish digital effects, with everything from chainsaw weaponry to giant scissors entering the fray.

It is less a film than a fever dream with a production budget.

Yet beneath the carnage is something considerably more pointed.

The conflict between Carmine and the residents of Yoshiwara is essentially a battle over cultural ownership. The American gangster sees the district as something to acquire, exploit and reshape for his own purposes. Nishimura responds by turning that clash into an exaggerated piece of exploitation spectacle, where cultural imperialism is answered with severed limbs, weaponised geisha and enough blood to repaint the streets.

Subtle it isn’t.

But subtlety was never particularly high on Nishimura’s list of priorities.

The film’s greatest strength is its willingness to embrace the ridiculous. A conventional action film might introduce a weapon and expect us to accept it as part of the world. Nishimura introduces something completely absurd and then seems determined to make it even more absurd. The result is a cinematic universe in which rickshaws become vehicles of lunacy, weapons emerge from unexpected places and characters can transform into things that would be difficult to describe without sounding like the result of a particularly feverish drinking session.

This is Gallows Horror stripped of the gallows and given a flamethrower.

There is also something strangely poignant about watching Geisha War as Nishimura’s final film. The director died in May 2026, making this an unintentional farewell from one of Japanese genre cinema’s great visual anarchists.

It is certainly an appropriate final statement.

Nishimura never seemed particularly interested in behaving himself. His cinema was messy, confrontational, juvenile, political, horny, grotesque and frequently hilarious. He understood that practical effects could be more than technical achievements: they could be jokes, provocations and punctuation marks. A severed limb wasn’t merely a piece of gore. It was a punchline.

Geisha War occasionally struggles beneath the weight of its own excess. The narrative is skeletal, characterisation is largely functional and the film’s relentless barrage of ideas can become exhausting. For all the visual invention, there are moments when it feels as though Nishimura has several films fighting for space inside the same one.

But perhaps that is part of its charm.

This isn’t polished underground cinema. It isn’t attempting to disguise its seams or convince us that its world is realistic. It is handmade, excessive and proudly artificial. The practical effects have weight; the digital effects deliberately flirt with cartoonishness; the action seems designed around the question of what could possibly make an audience yell what the hell was that?

And then, just when the film seems incapable of slowing down, it finds an unexpectedly reflective note beneath all the bloodshed.

That contradiction is what makes Geisha War work.

For all its ridiculousness, there is a genuine sense of resistance running through the film. Its grotesque spectacle becomes a weapon against the forces attempting to commodify and control its world. Nishimura takes the familiar machinery of exploitation cinema and turns it back upon itself, producing something that is simultaneously crude, playful and politically mischievous.

It is not his most accomplished film.

It may not even be his most outrageous.

But it is unmistakably his.

And as the final film from a director who spent decades proving that there was still room for strange, handmade, bloody and completely unclassifiable cinema, Geisha War makes for one hell of a final curtain call.
