Onechanbara: Bikini Samurai Squad
What they share
Both films are directed by Yôhei Fukuda, and they both carry the 3am cult mood tag, and they sit in Horror territory. If that's the register that drew you to Death Tube: Broadcast Murder Show, the second film will land in a comparable space — through a different lens.
3am cult
What Onechanbara: Bikini Samurai Squad is
Ruined Tokyo, sometime this century. Rotting flesh and a high, keening giggle. Aya hunts her father's killer, her blade the only thing between her and a zombie horde, her bikini somehow staying on. Peak mid-aughts J-horror knows its audience.
